2008 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.

2008 Mercedes-Benz SL550 Questions

have a squeak when driving (1 answer)

squeak appears to be behind me when driving, louder on rough roads and almost silent on smooth roads. squeak with top down or up; not as loud with top down.

it appeared to be locked in a lower gear. (1 answer)

I left a store and the car was very slow and the RPM's were up to 4000 plus and going nowhere. i shifted to N and back to D and it then started acting normal. I drove it back home next day about 200 plus miles and had no issues. Would it be a fluke or bite me later?

Has the Mercedes SL550 models had problems with the convertible top brackets? (1 answer)

We have a 2008 SL550 with less than 19,000 miles and the convertible top stop working. The service dept found that the brackets were bad. The mechanic stated they have replaced them on several other cars.

My car has 27,000 miles and starts shaking and making a funny noise. I have a 2009 GL 350, the display panel is not working. I really feel that Mercedes is no longer selling top quality cars that they use too.
