Thanks for the reply. Are you sure you had the same problem with your reps? Just find it strange that TPMS sensors on the X5 affect traction system. How is it related?

Shouldn´t the TPMS sensor warning light be on if the sensors are not detected? I have a Lexus IS350 as well with aftermarket wheels and no TPMS sensors. The TPMS sensor warning light is continuously on, but it does not affect traction control system.

Did you swap TPMS from original wheels into the reps or did you get a new set of TPMS ?
