C250 (W205) hesitating under full acceleration
Took it to a service station and was told that the high pressure fuel pump and an oil-related component had to be replaced although they couldn't find any notable issues when they looked at those parts! Total cost around $7500!
My question is that given the car drives normally in day-to-day conditions, what could be the issue? If the fuel pump is faulty, shouldn't it cause problems regardless of how fast you accelerate? Will appreciate your thoughts
