Mercedes-Benz B-Class - Mercedes B Class running rough on start - kevf66

Hi,

My wife had a B-class and we have had a number of issues with it.

Tonight she has said there's major engine vibration, almost like a wobble that you can feel through the car... also lights dim slightly as revs go up and down, can stall from time to time when moving and makes a bad noise when revs are fluctuating.

Once warm and run for a bit, all seem to disappear.

All in all dosent sound the best, has two logged faults on an OBD reader P0263 and P0272 but has had these a little while when car ran ok. Engine management light stays on all time plus coil light takes longer than expected when cold to go out.

Any clues on what to do next would be appreciated, Im aware there's quite a few issues here but wondered if there's a common source

Advice much appreciated

It's a 2006 B200 automatic.

Sorry forgot to put that in original thread

Take the car to a good garage and get it checked over. Better to get a inspected and the fault fixed now than wait for it to get worse and go BANG!

Agreed, assuming this is one, a Diesel specialist or a very good MB indy ASAP, this is not a job for a your average garage, nor, unless your pockets are bottomless is it a job for the main dealer either.

You do not want to leave Diesel running problems because massive damage can result.
