I thought Toyota had an extended warranty if you had regular servicing with them. Sounds as though you are given the brush off. They have a reader to check for wheel sensor faulty. Read thread for EV tyres for more on wheel sensors

No need to remove these at all , not even for the mot .

I thought that no dismantling of any kind was permitted for a MoT :-)

We told them it had a problem with the tyre pressure warning light, which was refusing to go out after a recent puncture

There's a reset button somewhere that most folk can't find, you'll have to RTFM. My 2014 Yaris doesn't have rear wheel arch liners, although a main dealer did manage to 'lose' my GB plate.

All cars with the TPMS will have the reset option if it won't reset you have a problem. I don't know want has gone on with the Toyota dealer may be they just ran out if time. Whatever very poor communication with the customer. I personally hate having to deal with garages, The modern car is just too complicated for its own good. Unless you have what must be an expensive TPMS reader you cannot tell what the problem is. You would think that your car at the very least would be able to tell you which wheel has the problem

It is an MOT fail if the warning wont reset

We’ve been back to the dealer today to get things sorted. It turns out that Kwik Fit had fitted a sensor which wasn’t compatible. The dealer have been helpful in that they’ve given us the sensor that Kwik Fit fitted and have written on the paperwork that it’s not suitable, so I will be off to Kwik Fit later ….
