2007 Mercedes-Benz SL550 ProblemsCheck 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.
The engine may develop a stalling and/or no start condition due to a failed crankshaft position sensor.
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.
