If the above-mentioned problem is detected, one possible cause may be an incorrect/defective tyre pressure sensor.
In such a case, the wrong tyre pressure sensors have been used for the winter wheels.
In order to exclude other possible causes of malfunction, electrical and mechanical system tests (in accordance with vehicle manufacturer specifications) and also a fault code query using a suitable diagnostic unit should be carried out. (Error codes have not been stored in the engine control unit)
If no further malfunctions are detected, the tyre pressure sensor for each tyre (i.e. 4x) (OE No. 5Q0 998 270) has to be replaced.
Please always observe the manufacturer's instructions.
Tip: tightening torque for screw/s on sensor (4 Nm).
Finally, a test drive should be undertaken in order to run a check on the repair work.
High-voltage components - risk of accident and injury (electric shock)!
Please note that such repair work should only be carried out by an authorised specialist workshop and that the vehicle manufacturer's repair and maintenance instructions are to be observed!
