2007 Mercedes-Benz SL550 Problems

Wear causes noise at vario roof seals on high mileage vehicles
On higher mileage vehicles, wear causes noise at the vario roof seals. Lubricating the seals can usually cure the problem; in most cases, the seals do not need replacement.

Mercedes-Benz has released a service bulletin outlining specific repair instructions depending on fault codes stored.
