Mercedes Repair Questions? Ask a Mechanic for Answers ASAP
,the 6-liter engines are the most complicated in the MB engine lines to diagnose, repair and maintain. Even perfectly maintained car can have the misfire isssues due to very expencive causes like coilpacks, ignition control modules, oil leakage into engine management components. I recommend to stay away from this engine. 55AMG much more reliable, with similar power output.
