2007 Mercedes-Benz C280 4MATIC 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 in the 2005-2008 Mercedes Benz C280 4Matic is known by Mercedes Benz to have issues due to a poorly manufactured gear on the balance shaft (also known as the counter-rotating assembly). Since the balance shaft gear is driven by the timing chain, which keeps the engine rotating synchronously, when it fails, the timing of the engine will change causing:
-Illumination of the Check Engine Light
-Rough Running Conditions
-Loud Rattle or Slapping Noise
-OBD Trouble Code P1200 and P1208
Correction for this issue is replacement of the balance shaft, or balance shaft gear. Replacement of the timing chain and tensioner should be done as well. The Mercedes Benz dealer may cover some or all of the repair cost on select vehicles as a result of a class action settlement.
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.
2007 Mercedes-Benz C280 4MATIC QuestionsI have the failed exhaust camshaft solenoid on my c280 and wanted to know if I can get it fixed under the recall for this problem? (1 answer)
The failed exhaust camshaft solenoid is on the driver side cylinder head and also on the passenger side intake. I was told by a repair pal certified repair shop that this problem is under the recall by Mercedes Benz and would be repaired at a Mercedes Benz dealership.
repair work was done to my 2007 Mercedes c280. The code shows 02 sensors were swapped, or crossed up. Will this affect the computer and cause the cooler fan not to come on.
