Mercedes-Benz SL550 Problems
Squeaking/Worn Brake Pads May Require Rotor Replacement Also
Due to the size and material used on the brakes of these vehicles, the brakes may start to squeak around the 50 percent wear point. The brake rotor surfaces become uneven, causing a lip to form at the outer edge of the rotor. Because of this, the rotors are usually replaced when the pads are worn (pad life varies depending on driving style and terrain).
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.
Early Versions of Central Gateway Module Have Software Problems
The early versions of the central gateway module (which allows different systems to communicate with each other) have software problems.
ABS Modulator Failure Due to Dirty Brake Fluid
It is not uncommon to encounter premature failure of the anti-lock brake system (ABS) modulator assembly due to dirty brake fluid. Our technicians recommend flushing the brake fluid every two years in order to help prevent this problem.
The Differential May Develop Leaks From the Seals or Cover
High mileage or older vehicles commonly develop leaks from the differential seals and/or cover. Our technicians recommend a complete reseal of the differential unit whenever these leaks are repaired.
