Self Leveling Suspension, Components and Installation Locations

Self leveling Suspension, Components and Installation Locations

Note:
^ During model year 2004, the Level Control System Control Module 7L6 907 553 A/B (200 Hz) was replaced by the Level Control System Control Module 7L0 907 553 F/* (800 Hz).
^ As of the implementation of new control modules, the wheel speed sensors are no longer installed, and the vehicle level sensors were adapted.
^ If a 800 Hz control module instead of 200 Hz control module is installed, also the vehicle level sensors must be replaced. The wheel speed sensors remain in the vehicle for the purpose of sealing the line.
