Ahh..I would hope he knows that . I'll call him t'moro just to make sure. Thanks for the info. By the way, is resetting a simple job?
Manually check and correct all four tyre pressures - then get in car, turn on the ignition, wait for all the warning lights and seat belt warning to go out - then press and HOLD for at least 2 seconds (and watch the speedo at the same time) - you should see the TPMS warning light briefly flash in the speedo, and hear a 'bong' to confirm it has been set. If this doesn't work, then the TPMS will need to be 'initially adapted' - same as before, but hold down BOTH the TPMS and the ESP buttons at the same time - for about 5 seconds.
You can try this yourself.
