Sunroof / Moonroof Drain: Service and Repair

Water Drain Hoses, Cleaning






Front hoses

The front drain hoses are routed through the "A-pillars" and end just above the lower front door hinges. The hoses are cleaned by working through the sunroof opening.


Rear hoses

The rear drain hoses are routed through the "D-pillars" and end at the sides of the body behind the bumpers. The hoses are cleaned from the bottom end of the hose.


Note: For cleaning, a self-manufactured cleaning probe (speedometer drive cable, or equivalent), approx. 2.3 m (7.5 ft) long, is recommended (e.g. Part No.321 957803 AF).
