Level Control System Components and Component Locations
Level Control System Components and Component Locations
• During MY 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 is installed instead of a ( 200 Hz ) control module, the level control system sensors must also be replaced. The wheel speed sensors remain in the vehicle for the purpose of sealing the line.
