Yefun EL50448 Auto Tire Pressure Monitor Sensor TPMS Activation Tool TPMS Reset Tool OEC-T5 for GM Vehicle Series (Orange)

bought a 3 year old 2016 vauxhall astra k, wheels had been rotated and one wheel registered as two places on tpms display.put car into learning mode, put unit next to tyre valve on tyre, pressed button, car horn beeped, repeat on other 3 tyres, horn beeped twice to confirm tpms learning completed. easy as pie, only took a minute or 2. i inflated tyes, the tyre position now shows correctly on dashboard display, recommend this product easy to use, its put a 9v battery in (note the polarity symbols as easy to insert battery wrong) then press the button next to tyre valve, you need to access tpms on dash and put it into re-learn mode, car then lights indicator next to wheel it wants to learn, front left first, horn beeps then lights next indicator (clockwise round car starting front left passenger side first).

Excellent tool. Easy to use and does it exactly what it is should. Under a minute and all done. 😀👍🏻

Worked on my wife’s meriva and my astra

Works perfectly on my Vauxhall Astra and is a bargain at £12.

Delivered before date due and product is a great tool and works a treat.

Fast delivery, easy to use, I'm happy with this tool.

So Easy to use , in my 2015 Vauxhall zafira tourer. Does need two people , one to put car into tyre pressure learn mode and one to press the tool upAgainst the tyre near the valve but not touching the rim !press the button it will flash for a few seconds and then the horn will beep once to say it’s been read ! Once all tyres are read the horn will beep twice to say complete then all pressures will show up on your dashboard! So happy it’s worked straight away! Can’t recommend enough, and for such a small price , you can’t go wrong! Especially when Vauxhall charges over 75 pounds to do the same job this has done!

Great value and easy to use.
