Mercedes-Benz SL550 Problems

Poor AC performance Due to Evaporator Temperature Sensor Failure

The evaporator temperature sensor can fail, causing the AC compressor not to cycle. If the AC compressor does not turn on, the AC system will not blow cold air. If the compressor is stuck on, the air will be very cold at first, before warming up.

Active Body Control System Can Leak Hydraulic Fluid

The active body control system can leak fluid from numerous areas, including the tandem pump, hydraulic lines, struts, and/or seals. If it is not repaired, the vehicle ride height could drop too low and cause damage to the undercarriage.

Check Engine Light Due to Faulty Camshaft Adjuster Solenoid

The camshaft adjuster solenoid (which is related to the variable valve timing system) may fail or timing chain/balance shaft components may wear, resulting in illumination of the Check Engine Light and various drivability issues. Mercedes-Benz has released a service bulletin outlining specific repair instructions depending on fault codes stored.

I love mine...It's the best car ever!!!
I purchased the SL in 2010, it had 10,400 miles on it. It now has just over 31,000 miles on the odometer. About 6 months ago a valve in the suspension malfunctioned. The extended warranty covered the valve replacement but I ended up paying $600 for fluid replacement. A month ago a hydraulic line in the suspension broke spraying fluid every where. A sensor periodically malfunctions displayi...
