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.

Check engine comes on all the time. Code check p0025 an p0015. Dealer says $800.00 to investigate issue. It is totally not necessary as it is well reported that this is a major engine flaw. Very disappointed in the quality and the reaction of the MB dealer

Check engine light came on. I have noticed that shifting was louder and less smooth. Replacement of Camshaft Solenoids costing $475.00, including parts, labor & tax.
