GT86 TPMS Error

Sounds familiar! I had the exact same problem with my GT86. Have you considered that the sensor battery might be dead? They don't last forever, and that mileage is getting up there...

Thanks! I hadn't thought about the sensor battery. How did you fix it, and did you have the same symptoms, like the speedometer error?

Yep, everything was the same. 'Low tire' warning, the light on the dash – the whole shebang. I'd advise getting it checked at a workshop; they can easily test the sensors and replace them if necessary. It's a pretty common issue, apparently.

Thanks for the advice! It seems like the sensor battery is the most likely thing. I'll book it in at a workshop to get the sensors checked and probably replaced. They quoted around 280€.
