Follow instructions on initializing Run Flat Indicator Initializing Run Flat Indicator (RPA).





Labelling of wheel electronics
1 - Transmitting frequency of wheel electronics
2 - Large Torx socket
3 - BMW part number
4 - Tightening torque of Torx screw and union nut
5 - Width across flats of union nut
6 - Identification code of wheel electronics
7 - Date of manufacture of wheel electronics





Removing wheel electronics
Release Torx socket screw (1).
Remove wheel electronics (2).





Check filter surface (1) for pressure measurement for contamination.

Note:
Wipe filter surface with a clean cloth only.
The wheel electronics must be replaced if the filter surface is contaminated.
