Please please help.
I'm totally new to this kind of site but need some help.
I have a 2004 320d e46. 130k. Black smoke appeared on acceleration and a loss of power around 2000 revs. The fuel consumption has reduced a lot, there is also a strong fume smell around the car. The car has always been serviced regularly. I noticed that if I unplug the MAF filter whilst it's slower the smoking and hesitation stops....great I thought so a new bosch air flow meter was fitted,...no difference at all.
I was hoping someone out there may of had the same problem. Please forgive me as I'm not a mechanic just can't afford to pay BMW rates at the moment.
