REMOVING AND INSTALLING/REPLACING A TIRE PRESSURE CONTROL ELECTRONIC WHEEL MODULE (GENERATION I)
Notes
IMPORTANT: Before removing and installing, check which generation of tire pressure control electronic wheel modules are fitted (see BMW Spare Parts Catalogue).
If the electronic wheel module has been removed, the complete valve must be replaced.
These instructions describe how to install the (old) 2-time operating valves.
These can be used if still in stock.
1-TIME OPERATING VALVES , see repair instruction.
NOTE: 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.
Before the installation of new wheel electronics with valve, thoroughly clean the valve bore of the wheel rim.
Do not treat electronic wheel module with solvents, cleaning agents etc. If dirty, wipe with a clean cloth only.
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 Torx socket screw (1) in electronic wheel module (2) and secure firmly.
Twist new valve insert (3) by hand approx. 3 turns onto screw (1).
NOTE: Do not tighten screw; electronic wheel module and valve insert must be loosely joined together.
