WARNING: This page does not describe the selected car, but rather 7 other vehicles, including the 2014 BMW X6, 2013 BMW X6, 2012 BMW X6, 2011 BMW X6, and 2010 BMW X6. However, it is still accessible from the selected car via links, so may be relevant.
IMPORTANT:
Before removing or refitting, check which generation of wheel modules is fitted. If the electronic wheel module has been removed, the complete valve must be replaced.
NOTE:
There are two different electronic wheel modules. The SP303 electronic wheel module must be used with RDC-01 and RDC-02 from model year 03/06. The Gen3 electronic wheel module must be used with RDC-LC from model year 09/09. If a tyre sealant has been used, replace the electronic wheel module. When a tyre has been removed, do not clean the rim with installed electronic wheel module with high-pressure cleaner. Do not treat electronic wheel module with solvents, cleaning agents etc. If dirty, wipe with a clean cloth only. Before the installation of new wheel electronics with valve, thoroughly clean the valve bore of the wheel rim. Do not clean electronic wheel module with compressed air.
