There is a fault within the wheel electronics.
After removal of the tire, the wheel electronics -A- can be seen at the valve in the outer rim well base.
1. Release wheel electronics from valve using a Torx socket screwdriver T 20 (if necessary, counter with a suitable assembly pin, e.g. steel pin
[diameter] approximately 1.8 mm in bore at valve foot) and remove.
2. Then unscrew union nut and remove valve.
Installing wheel electronics
When replacing the wheel electronics, always use a completely new valve and a new fastening screw!
The tightening torque for wheel electronics/valve is 3 ft lb. (± 0.4 ft lb.)!
The wheel electronics must not come into contact with the tire fitting paste or solvent!
Every tire set or wheel change must be communicated to the control unit. In particular, this includes the case where wheel positions have been
interchanged. For this purpose, in the instrument cluster under main menu > Tire pressure > Adjustments, always select the tire type and tire size.
