3611533 Removing and installing/renewing tire pressure control wheel electronics (2nd generation)

WARNING: This page does not describe the selected car, but rather 11 other vehicles, including the 2011 BMW 323i, 2010 BMW 335xi, 2010 BMW 335i, 2010 BMW 328xi, and 2010 BMW 328i. 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 (See BMW parts catalogue)
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 tire sealant has been used, replace the electronic wheel module.

When a tire 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.

IMPORTANT: Before the installation of new wheel electronics with valve, thoroughly clean the valve bore of the wheel rim!
Also make sure that the valve bore is free of burrs

Installing electronic wheel module

Insert new square-head bolt (1) in wheel module (2).

Screw single-use valve insert (3) three turns onto square-head bolt (1).

NOTE: Make sure the square head screw (1) fits exactly in the holder for the electronic wheel module!

Screw on sleeve nut (1) by hand as far as it will go.

Tighten sleeve nut until the inner strip-off ring breaks. Breakage is perceptible audibly and tangibly (momentary drop in torque resistance).

Then fully tighten sleeve nut (1).

Tightening torque 36 11 1AZ .

IMPORTANT: Fixing must not under any circumstances be retightened!
The square-head bolt should be located precisely in the wheel module holder.
After tightening, the electronic wheel module must fit snugly on the rim!
