2008 Mercedes-Benz SLK280 ProblemsCheck Engine Light and Engine Noise
The engine in the SLK280 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.
Vehicles equipped with a 7-speed automatic transmission may develop a rough shifting condition, most commonly going up from first to second gear and going down from third to second or second to first gear. Our technicians tell us this is due to an internal component failure. Mercedes has released updated parts; the transmission will need to be removed and disassembled to complete the necessary repairs.
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 SLK280 RecallsDriver's Frontal Air Bag Inflator Ruptures And Sprays Metal Fragments
The driver's frontal air bag inflator may deploy the air bag with excessive pressure, resulting in the inflator rupturing and causing metal debris to be sprayed onto vehicle occupants. Dealers will replace the driver's frontal air bag module free of charge to resolve the concern.
Transistors used in the front signal acquisition and actuation module (SAM-F) may have been damaged during module assembly. As a result, the module could fail without warning, increasing the risk of a crash. Dealers will inspect and replace the affected modules as necessary. This recall is scheduled to begin on May 2, 2008. The Mercedes-Benz recall number is 2008 030005.
