Major Failure on CLE53 for the first time
Hey , During some dynamic driving, during one of the hard accelerations at full throttle, the check engine light came on and the engine started shaking. After turning off the car and waiting a bit, the error was gone, but upon another hard acceleration, the error reappeared and the whole engine started shaking again.
The car went to a Mercedes dealership. So far, the scanned codes show a turbo actuator fault and a misfire on cylinder 6. They’ve been diagnosing the car for 3 days now and still don't know what the root cause is. What I found online is a possible issue with the wiring harness—specifically, it might have melted near the 6th cylinder, which is closest to the turbo's heat shield.
This is definitely not the quality I expected from Mercedes. I’ll keep you posted on what happens next, because I’m probably just the first, but not the last one with this problem. The car has 40,000 km on the odometer, which is about 25,000 miles, I think. So it's a bit much, but nothing crazy.
The funniest part is that in Europe we get a two-year warranty, and this breakdown happened exactly two weeks after the factory warranty expired. Fortunately, I have an extended Mercedes warranty, so I hope it will be resolved free of charge.
