Hey guys im after a bit of help, just recently my 320d has developed a power loss at low revs, turbo kicks in fine at around 3000rpm, ive changed the maf and its a little better but still not the way it should be. Ive now also noticed that when i take the car over 3500-4000rpm i get a burst of black smoke and the car starts to judder!!. anyone ever experienced this before? could it need a new map sensor?? im completely clueless.
any help will be much appreciated.
