2011 Mercedes-Benz E63 AMG QuestionsRefine by vehicle
My car is almost unbearable at low speeds and the dealer can do nothing for me. They know what the issue is but won't spell it out, I've learned what the problem is on this site. Since I just got it almost three months ago I can't get out of it without coming up with a substantial amount of money for something else and now my wife who didn't notice it at first now does with a vengeance. I noticed that fuel booster and racing fuel makes it run like silk but its expensive and I don't know if it's detrimental to the car.
