EGR valve,
the cam sensor
the MAF sensor
the oil filter
the air filter
the diesel filter.
There is no metel filings in the diesel filter,does anyone have any ideas as im at a total loss,could this problem be caused by the MAP sensor? Thanks to anyone who replies to this message & if i dont reply straight away its because im busy with a sledgehammer & 1 vauxhall vivaro van!
