Mercedes C220D: I have a mercedes wagon, C220D .. Last 3 months

Customer Question

I have a mercedes wagon, C220D .. Last 3 months i have noticed on light acceleration and deceleration a distinct vibration or friction almost as though something is slightly out of sync. on harder acceleration it is less noticeable but the car feels rougher in general than purring the way it used to! any idea what that may be?

Hi there,
How many kms? 5 years old now.
Diesel, could be number of things.
Quite common these days with Diesels to have injector issues, carbon buildup within the head, including EGR passages, carbon buildup within turbo exhaust housing.
I would change fuel supplier for a while, and see how the car reacts.
Might save you some money.
