Anyone know what these are? Are they tyre pressure gadgets? took my Mazda CX7 to local tyre fitters to have my winter tyres changed back to summer tyres (didn't feckin snow once up here - total waste of time!) and noticed this morning that the tyre pressure warning light is on and won't go off - tyre pressures are fine - no flats. When I removed my winter tyres from the boot 2 of these wee 'transponders' fell out of the tyres - they clearly show signs of having 'snapped off' something and the garage have obviously then placed these inside my winter tyres when giving me everything back. What do you reckon? do my summer tyres need to come off and these put back in? Has my local tyre fitter butchered the job? - cheers guys - any help greatly appreciated

Yep. I suspect that should be attached to the top of the valve (or possibly bolted to the inside of the rim somewhere, not sure how Mazda do it).

ETA: I think (not sure) that the pressure light being on is an MoT failure these days, too. Quite a lot of the warning lights are.

Ouch, they ain't cheap either. £50 quid each from the online shops, I'm guessing considerably more from Mazda.
