Autel OBD2 Scanner MaxiDiag MD906 PRO, 2026 All Systems Car Diagnostic Tool

To those who gave this unit one star because you couldn't be bothered to contact customer service to get things figured out: get a life. This scan tool does more than any other scan tool on the market and it does it with flying colors. I've used scan tools from Innova, Actron, OBDLink and other companies, and they don't even come close to the usability and functionality of this tool. You can do live scans, make-specific scans, generic scans, scans on the powertrain module, transmission module, ABS module, body module and more. I've done scans on 1998 Volkswagons through 2013 Audis and it has NEVER failed me. I've probably scanned 50 different cars from the USA, Europe and Asia in the 7 months that I've had this and it is by far the most thorough tool on the market. It catches things that don't even show up on the highest-priced Innovas (even if you use their over-priced make-specific flash modules.) This tool uses software from the MaxiDAS, which many pro mechanics use, so what you're essentially getting is the scan capabilities of the MaxiDAS without the bi-directional capabilities. I was fortunate enough to purchase this right when it came out and was priced around $220. It's since gone up in price significantly, but knowing what I know about this tool, it's still worth what they charge. Now that I'm using the MaxiDiag MD802, I wish I hadn't bought the OBDLink OBD-II USB Scan Tool Interface Adapter (425101) , which after spending $$$ on the tool and the pro-upgraded software, actually ended up costing me quite a bit more. The OBDLink and the pro software only churns out generic info and is so much less capable than the MaxiDiag, that it never leaves the cart anymore. The Autel MaxiDiag finds issues that you will never find using a generic tool, inlcuding factory Bluetooth issues, lock switch problems, factory-specific ABS faults, etc. It lets you clear just about every code your ECU can come up with. This is a very important feature since on some makes, such as Hyundai, you need to clear the codes after you do the fix or the car will continue to think there's a fault and it will not work properly until the code is manually cleared. This is now becoming a common thing with manufacturers since they want you to take your car to a dealership, where it costs $120 just to use a factory tool to clear a code, which only takes a couple of minutes. In this regard alone, the MaxiDiag paid for itself after about four uses. For the sake of full disclosure, I was having a problem updating my scan tool the first time I tried Autel's Auto Update software. It was admittedly my fault, since I didn't follow the instructions in the manual exactly as written. I got in touch with Autel customer service and they fixed it in a day. You can't ask for more than that. The updates have been super easy to do and as of today, I'm running V2.0 of all the makes. There are 47 different makes represented on this tool, if I recall correctly, including Dacia ("GOOD NEWS!"), GM, Ford, Ford (Europe), Toyota, Nissan, Subaru, Holden, Ferrari, Lancia, Chrysler, Suzuki, Fiat, Mercedes, Audi, Volkswagen, Honda, etc. etc. etc. I can't really think of anything bad to say about this tool. It's easy to use, professional grade and to be honest, it's a bargain when you compare it to the next closest thing out there that has the same capabilities. EDIT (November 2016): I've loved using this tool for the past few years. Autel has done a really good job with the software updates and its website is finally up to the level that this tool deserves. I recently paid $100 for another year's subscription to tool updates and am running Version 6+ on pretty much everything (meaning it's good on most vehicles up to the current model year.) As a scan tool, I still think this product is hard (if not impossible) to beat for the price. Since the tool originally came out, Autel has added additional functions like oil change light reset and several other handy functions. Five stars all the way.

Scanner is all systems model, very impressed in initial quality....hope it will last Comes with plastis hardcase, cd, manual,4g sd card, usb cable, obd. Cable. Scanner can be powered from usb cable by computer or charger or by other adapter when away from car. Long review/ important info for some users i have tested it on 2001 crv, 2008 bmw 328 xi , 2005 cadillac and 1997 rav4. on crv: it read srs and abs, it disconnect from crv a few times in abs mode but always reconnects. I was able to see wheel speed sensor live data and other live data and generic obd info on bmw you need to know the car generation or it might appear the scanner does not read your car..IT DOES... The bmw named above is 4th generation so in my case i selected 3 series, then E90/91/92 which is the 4th generation/year range code name and then i get the prompt for specific model and choose 328 xi. Saw over 100 + choices for 3 series, 4 generation alone...Unit scanned over 30 modules in bmw and did show a few faults ( i did not varify faults..but most modules reported ok) and no mil/ check engine light present..just connected for testing. Only module explored was tire pressure, Scanner read sensors. One problem with bmw.. generic obd check froze scanner twice while module check works great....issue may only be this bmw and since you can read the modules otherwise its not a big deal to me On cadi it read modules and even confirmed with more detail what the onboard information center gave such as passenger side open loop on airbag among others 97 rav4 ..scanner reads live data..use to find bad connecter on oxygen sensor and varify fix... i think it will not read modules before 2000 ..i think i read somewhere in manual Unit updates flawlessly with vista pc. Inserted cd to update and was led to wesite wich redirected me to autel new website. I was required to sign up for an account...once that was done i was able to update after providing serial # and register password found in scanner setup section. software is nice in that it shows all possible updates and when you insert your sd card from the scanner in computer reader, it compares what is on the sd card and only shows updates that are not on the card..so you dont have to check line by line...software does it..you choose to install or not..i also like this because i intend to backe up.my sd card...size sent is 4 g.....you will need a larger card..maybe 8g or more to download all car model software and for saving live data scans. CON: none when i capare its ability to read modules as compared to innova and actrons line up, i can live with a few disconnects on some modules. But for information sake: does not read modules before 2000 (I THINK) Pro: like update software and by sd card, went smooth via vista. Can back up card Power via usb cable away from car Read 30+ modules on test bmw Live data works well Note/reminder: for some vehicles..you need to know car generation name...took me over two hours to figure out ..used google after initial failure to scan

I will update this review when and if I am able to get this working (see edit below). First off, gotta love that one-day free shipping with Amazon Prime! Also, the tool comes very nicely packaged in its plastic carry case, which holds the tool firmly and has room for the cables and manual. The manual is out of date, as is the downloadable .pdf copy. It tells you to go to a non-working website (www.maxidas.com) to register and update. The first thing I did, based on reviews here and elsewhere, was to go to the working website at pro.auteltech.com, where I registered successfully and downloaded the PCsuite software, which I had to do because the CD that came with the tool would not read fully on my computer. I ran the software, which installed Autel Update and Autel Printer programs. I ran the Autel Update umpteen times with no joy, only "download failed". Following advice on a forum to another customer with a similar problem, I reformatted the SD card that came with the device and tried again. Unfortunately, (my fault for being overconfident given that the advice was from Autel) I did not back up the existing files on the card before reformatting. I tried umpteen more times to download each of the software versions available on the site, and again no joy. The device came with version 4.4, but the site offered 4.3, 4.4, 4.5, and 5.1, as I recall. I say "as I recall," because pro.auteltech.com went offline last night and is still down, so I have no known way to even restore the software the device came with. I did submit a tech support request via the website before it went down, but have not heard from them. I understand why, as their US branch is NY based (their phone contact info indicates 9AM-6PM Eastern Standard Time M-F availability with a domestic number). It is Sunday, and the storm is severe, so perhaps their server lost power and perhaps they are not able to access it due to the weather. On the other hand, they are apparently being sued for copyright infringement by Ford, which makes me think their site could have been shut down by a court injunction. https://www.eff.org/deeplinks/2015/01/ford-tries-shut-down-third-party-repair-tool-copyright. In any case, the device is completely useless at this point, partly due to my own failure to back up the original software or use a different SD card. I'm glad I bought it from Amazon, because I can always return it, but I didn't buy this to return it, I bought it because I want it to work as advertised and as reported by so many satisfied customers reviewing here and elsewhere. Hoping to update soon with great success and at least a 4-star rating, but as of now, 1 star is the best I can offer. Edit: It is several hours since I posted the above, and I am pleased to discover that the pro.auteltech.com website is up and currently upgrading my card. It does the downloads quickly, but the installs take a loooong time. Not sure if this is because the site is involved, because my computer is normally pretty fast. As I said, I'm using a high speed card with plenty of space. I am a four-vehicle owner who does most of his own mechanic work, not a pro, so it may take a while before I have a large amount of experience with this device (and I hope, of course, not to need much). But I will be reporting how it does with my diesel 2007 Dodge Sprinter, which currently has lit check engine and SRS lights, and needs an oil change reset. As of now, I have upgraded my review to four stars and look forward to changing it again to five if all goes well. Edit: The speed of the SD card makes a huge difference. I used a #10 (fast) card when installing the updates. When it was done, which took several hours, I realized that it would fit on the card the device came with, which is a #4 (slow) card. I hadn't decided which card to use in the device and which to keep as a backup. Now I know that I'll be using the fast card in the device, because simply copying the files from my hard drive to the slow card started last night before I went to bed. I slept for about 7 1/2 hours. The process, according to Windows, is only 82% complete and still has about 5 hours and 45 minutes to go! I'll compare a specific operation with each card later and relate how long it takes using each. Edit: Well, I'm very surprised. I've only done one test to compare SD cards and their working speeds, but here's what happened. I did a scan of all systems of the Sprinter. The #10 (faster) card completed the scan in 3 minutes, 55 seconds. The #4 (slower) card completed the same scan immediately after in 3 minutes 26 seconds. Not a huge difference, but the opposite of the results I had expected. Prior to this speed test, the scans found several faults. I was able to save them to the device and delete from the vehicle computer all but two, which were the only two current faults. One is in the SRS (supplemental restrait system) that was identified as a short circuit in the squib of the driver airbag. I had removed the airbag portion of the steering wheel in an attempt to access the turn signal/windshield wiper switch which caused the SRS dash light to go on (one of the reasons I bought the device, as it has the capability of shutting this off without paying $140 to the dealer). I have yet to remove it again to find the short. The other fault was a short in the light that illuminates the ground and step below the driver door when the door is opened. It gave me a clue as to where to look for that short that I had not considered before. I haven't yet traced that down yet either though. I should add that there is one more fault that is causing the check engine light to go on. The device turned the light off, but I have not resolved the issue in the EGR cooler (I'm sure it's clogged with soot--a full day job for me to remove, clean, and replace, or $250 quoted by a non-dealer Sprinter specialist). If I run the vehicle through another diagnostic cycle by driving it, I'm sure this will come up again until I get the cooler cleaned. But it is good to know I can turn off the check engine light with this device.

Works good but manufacturer does not honor their claims. Initial purchase was based on the fact that there was lifetime update, hence the reason I purchased the unit. The updates stopped after one or two years.

I recently bought a 2008 BMW 650i convertible and it's had a few minor issues. The most recent was an error message that the PDC system (park distance control) had failed. The PDC system is extremely simple -- just some small sensors on the front and rear bumpers, and a control box in the trunk. However, because these are non-returnable electrical parts, you can't just buy a new sensor (they are $200+ each) and swap out parts until you find the cause of the problem. Instead, you need to be able to pinpoint the problem FIRST, before you can start fixing it. To do that, I needed a code scanner that could do more than the basic $30 units. I watched a YouTube video that showed a guy diagnosing a BMW PDC failure using this exact model scanner, so I decided to pull the trigger and buy one. I was slightly nervous because there are apparently two different versions of the MD802 scanner -- one of them is a more limited version that only handles "4 systems", while the other version (which is physically identical) can read "all systems". This made me worry that I'd somehow pick the wrong unit and it would not be able to talk to my car's PDC computer. Well, thankfully everything worked out fine. My code reader arrived today (VERY fast shipping). I simply plugged it into my car's OBDII port and started reading codes (there were a LOT of codes on my car....which is apparently not unusual). Anyway, I eventually found the menu for the PDC computer, read the codes, and sure enough -- it told me exactly which parking sensor on my car had failed (front, center, right). I confirmed this by pulling the sensor, swapping it with one of the other front sensors, clearing the codes then putting the car in gear to trigger another error message. I was very pleased to see that my code reader was now correctly reporting that a different front parking sensor had failed (because I moved the bad one to that location). Now I just need to order a new sensor. Once that's replaced, this code reader will have paid for itself -- I don't even want to think about how much the BMW dealership would have charged for this simple job. So, I have only owned this unit for one day, but so far I am 100% happy with the results.

Full System, All System, Four System, what is it!!! I read the reviews, the Amazon write-up, and the Autel website propaganda. Amazon's descriptions and pricing seem to add to the confusion. Autel customer service helped, a little. According to Autel, they DO NOT sell online, so any Autel code reader bought online is basically a knock-off and could be anything. Further, any sold by a store in the US is legitimate, and is the "all system" version. Autel does not sell the others inside the US. This model is about $150 cheaper than the "all systems" unit on Amazon, as well as those in the auto parts stores (the "real" ones). I needed a code reader and have had generally good support from Amazon, so figured I'd risk it, and send it back if necessary. Some have mentioned that the website would not recognize their unit, or that the updating was painfully slow. This is what I did (mostly, followed directions in the manual, which you can download from Autel's site before you buy): 1. created an account on the Autel website (don't need any information regarding the unit to create an account) 2. registered the unit (with info you find at "setup/about" when you connect it to your PC to power it up) 3. copied the entire SD card (92,XXX files, 3.77 gigs) to my hard drive for a backup 4. copied all those files to a 32 gig card (much more than I needed, but some mentioned the supplied SD card was too small) 5. verified that the unit and website were happy with the substitute card 6. updated - yes it is slow I don't know enough to determine if it will do everything it's capable of, but I suspect it does. I've used it to scan and clear codes on a 99 Neon, to scan and collect live (driving down the road) data on an 07 Yukon, and attempt to scan an 05 Crossfire. The Crossfire is supposed to require equipment that only some authorized dealers have, but I got a basic scan, and the machine found no trouble codes. What the machine told me matched well with known information for the Neon and Yukon. It did not correctly identify rat damage on the Crossfire. I am happy. Lots to learn now. One significant issue. Although the unit looked new, I had to use needlenose pliers to remove the SD card. It had been forced in upside down (relative to the correct position, at least). It appeared to have no damage. It had been used to collect data on a Benz, and when I registered it, I did get a full year access to updates, but only six months warranty. Amazon (NOT another seller) sold me a used unit. That's disappointing, but I risk all the problems again if I send it back. Will update if I have possibly useful info. UPDATE 23 JUL - one email to Amazon, full warranty period will be honored. Issue resolved easily. Much less trouble than returning it. Many potential problems discussed regarding this machine; not have materialized for me. Sorry, forgot to mention - I downloaded the PC suite software from the Autel site, which seems only to let you update (that's important), and PRINT. Some mentioned no success printing. I connected the unit by USB cable and could print from it to the screen, basically a text file. That I could cut and paste and do simple edits, and copy it to a Word file. So, you can generate a printed record and save to an editable file. That's all I know so far.

This unit is shipped labeled as the ALL SYSTEM diagnostic tool. It appears to cover all makes and models since 1996 and mine was loaded with the latest software version. It also includes the Autel Application CD, the OBD II connector and a USB cord to connect to your computer, and the manual. The whole thing comes in a nice hard plastic case. You can download the latest software version online and transfer it to your MD802 with the USB connector. The unit is powered by the USB cord @ 5V DC and by the OBD II connector @12V DC from the vehicle's electrical system. There is also a 3.5 mm plug in the side which will accept an adapter. You can get it on Ebay for about $6 but be sure the power supply is only 12V DC. It has a SD card in the opposite side that you can remove and put in your computer if you have a standard SD slot or USB adapter. Mine has a 8GB class 4 card but I believe it will accept up to 16GB class 10, however I don't know if that would provide much of an advantage. The software is compatible with all windows programs up to version 10. It is apparently not compatible with Mac IOS. The MD802 is easy to use and has so far worked with Ford, GM, and Toyota cars I tried it on. It is not bi-directional but will clear trouble codes easily. For the price (less than $200) it is well worth the money. I would definitely recommend it for the pro or the handy person who owns cars.

Exactly what I needed to read and reset the SRS codes on our 1998 Volvo V90. Finding a modestly priced code reader which accesses the Volvo specific other systems is difficult, but the MD802 did the job. It turned out that I had turned the car on with one of the seat belts out while I was replacing the worn belt and this had set a trouble code. This tool let me read that code and then reset it. Better known code readers like one of the similarly priced Innova scanners just said "sorry, this vehicle not supported for SRS codes". The one strange thing is that the unit doesn't have any built in battery. Reading it, downloading updates and so on require either plugging into an OBDII connector or buying an accessory 12v adapter it didn't come with. Annoying, but something I can live with in return for the comprehensive system coverage on our older Volvo.

Let me start off saying, WOW! Autel makes one of the best diagnostic equipment of the market and i own multiple Autel products. I am a mechanic by trade and i can tell you that this unit can do it all for you for a fraction of the price of other scan tools. I have a Snap-On truck that comes and tries to sell me a scanner costing $2200, not even kidding and it can't even do half of what this scanner can do. I would like to start of saying why i purchased this scanner, i purchased it because of the portability of the small tool and need to scanner a body code of my truck and needed a lightweight professional scan tool. Quick In depth Review: This tool can really do it all for the price! It can read Engine, Transmission, Airbag, EPB, ABS, Chassis codes, Body codes, even more (I have a technician in my shop, he paid $1100 for his scanner and can't even read body codes.) - It can read codes, erase codes, display's live data of all systems (if available by the manufacture.) For example, If you have a check engine light on and you have a misfire code of P0300 (Which is a Random Misfire Detected if anyone is wondering.) You can go into live and determine what actually the engine is telling you not just guessing you might need to replace your spark plugs or wires because not all causes that's what it is. You can accurately determine the problem the first time and not spend countless hours and money trying to figure out the problem. The ability to see and record live data is very helpful to diagnose issues. Adding to that, i can also do some TPMS diagnosis. I had a woman come in wondering why her TPMS light would always come on even though all the tire pressures where correct OEM spec. So i plugged this scan tool in and read the Body and Chassis codes and come up with the TPMS Module code U0127 (Lost communication with TPMS Module.) Ending up the module needing replaced but she wouldn't have known that without the scan tool reading the code. I was even able to graph data of the module when i put the new one it. Amazing! - Anything 1996 to present has OBll (This tool can read OBl, but only has the ability to read a code and is difficult as some manufactures doesn't support it.) This can read anything from American (General Motors, Ford, Chrysler) to European (Volkswagen, Audi, etc,) to Asian (Honda, Toyota, etc) It can read, erase, live data on all modules across many different manufactures. I work with a variety of vehicles and it can do it seamlessly with any manufacture (That being said, just because i can read a certain module of my truck doesn't mean you will be able to read the same module on a different truck. It will not scan every module in the vehicle, meaning it only scans the module your vehicle is equipped with. It will scan only what is available from the manufacture.) In addition, some manufactures won't let you access a module and scan only accessed with a OEM Scan tool for that manufacture. An example would be a 2010 Chevrolet Avalanche equipped with a Heated Seat Module and then plugging in to a 2010 Honda Ridgeline equipped with a Heated Seat Module. Two different manufactures, Honda may not let you access the module but owing a Chevrolet there is not problem accessing it, this is only an example but manufactures want you to take it to them to repair, that's how they get you in the door. - Newer vehicles meaning 2012 - 2018 most likely as i have seen give you more data because the OBll system is more advanced and more specific which also various across each manufacture. With OBlll coming soon which will be the most advanced system on vehicles made it will open up a variety of opportunities of diagnosing repair. - Operating System, The operating system on the tool is fairly basic, click scanning engine codes, scanning the entire body or chassis system, click for settings, etc. It is straight forward. I can say though for the average user that may have never used a scan tool this advanced. It can get complicated, for example when you plug it in to scan the engine light it will ask you which module you want to scan (on my truck i am talking about 2007 Avalanche, it asks me which module meaning the "PCM" or "ECM" . It makes it more complicated because a code could be in either module and producing the check engine light.) It doesn't have that on all vehicles but it just to be aware that there may be one, two, or three depending on the vehicle and you may have to go into each to find the code. It can get complicated if you have never used a scan tool like this before. It goes very deep into the modules of vehicles, but the way Autel has it set up, it basically walk's you though the process. - EPB (Electronic Parking Brake). This is such a useful tool on modern day vehicles because as many are produced they are coming with electronic parking brake instead of cable operated. This is more of useful too for mechanics as this is to deactivate them while servicing the rear brakes so it does apply with servicing them as i have seen it happen because they were unaware and isn't pretty to watch (Expensive meaning). Not the average person using the tool may ever use the feature but is handy in case you ever do need to service the rear brakes but this feature is mainly more for mechanics. - Oil Life Reset, Autel makes a tool just for resetting oil life and as vehicles advance, manufactures and making it harder for people like me to reset something simple as a oil life. It has gotten so complicated that is takes sometimes an hour to reset one vehicles oil life. This tool can reset oil, spark plugs, air filter, and plenty other services on all vehicles. I can say all because it really can, SERIOUS. I reset a oil life for a 2016 Lamborghini then used it for a 2017 Audi Q7 then for a 2013 Chevrolet Spark. It is really simple, plug it into the OBDll port and click oil life and follow the prompts on the tool. Complete. Such an amazing feature too have in a tool because it is getting to painful to spend time figuring out how to reset oil life on every vehicle. - Updates, this tool does come with a year free of updates meaning whenever you buy it. You have a year to update the tool and then you have to purchase additional updates. I am not sure the fee because i am still on my free year updates. I do not believe it is that expensive, but as a tip. Update the tool as soon as you receive it because it probably has been sitting around outdated for a while and Autel produces updates for this tool almost every week so it is never outdated. *Tip* As soon as your yearly free updates run out, update to the latest because in most cases you may not even need 2018 or 2019 vehicles. For me, i would update to the latest and if i really need update i will purchase it but i can't really see a 2018 or 2019 vehicle needing a scan for a engine light. To update the tool, you download the program from Autel to your desktop and the tool comes with a Memory Card that you remove and insert into your computer. 10-20 minutes later your done and inserting it back into the tool. Absolute fantastic! This tool is very advanced for someone that is starting out because it can read so much more that a basic OBll scanner. Most scan tools just read, erase codes and that's it will a few small other features. This tool does it all will do it all, it can scan deep into all your modules which other scanners cannot do. If you are not familiar with one, then this tool may not be for you YET. Buy a cheap basic one then go from there, but if your feeling optimistic about it i say go for it and purchase this tool because it really can do it. Like i said previous, it has a very easy operating system. So your not confused of what your going into. I stated at the top of this review why i bought the tool and i needed to scan my Service Park Assist on my 2007 Avalanche and needed a scan tool to scan body codes. I bought this and plugged it in and realize when i scanned my entire module system i had 11 other codes from Radio to Window to speaker codes. It was absolute amazing of all the codes i pulled, not for my me because it means more money out of my pocket. All this for the price of this scanner is unbelievable i must say, it is amazing. I highly recommend this tool to anyone, i seriously do!

Interessanterweise lag in der Originalverpackung nicht das AUTEL MD802, sondern ein billiges Gerät von Konnwei, das KW808, welches man hier bei Amazon schon ab 30,-€ kaufen kann. So nicht! Das Gerät ging zurück!

arrived on time, works well, requested updates to the seller and language pack. Everything is done, I update, I think it will work great. Faith quality

Quick Review: This tool is simply AMAZING! The ability to scan all 4 systems in great depth is awesome. Reads and clears trouble codes on engine, transmission , airbag, and ABS failures. The ability to see and record Live Data can be VERY USEFUL to diagnose issues. Has the ability to quickly read and clear codes in almost all modules for European, Asian, and Domestic vehicles 1996-present. Be aware it will not scan everything on all models....it will scan what is available to it. Newer vehicles generally give more readings and they are also more specific. It's got learning curve if you never used one of these before but do not let that scare you. Was able to scan and clear MIL from Emission control issue in my 2013 F150....tool even recognizes truck specifics like VIN, engine size, how many valves etc. Also works well on our 2008 Chrysler Aspen. Cleared 2 MIL codes that were also emission related. Can even view information on the radio.....wow! (found 2 faults on speakers 5 and 6 - Open Load Detected) It also noted that 2 of the TPMS sensors are receiving too much voltage...try that with another scanner of this cost. Includes a year of updates..... HIGHLY RECOMMEND THIS UNIT!!!!

修理工場を営んでるお友達がMK808で診断してくれ、 機能とレスポンスの良さは良かったです。 個人使用なので同じものとはいきませんが今後も使う 予定なので同じメーカーのMD802を購入。 日本語化もAUTELサイトに登録してから販売元に シリアルNoを連絡すれば簡単にできました。 SanDisk 16GB クラス10が標準装備されてました。 マツダスピードアクセラに接続し必要な情報は 確認することが出来ました。 他の車種にも活用出来そうです。
