The turbo went on my 320d back in july. i got my old turbo reconditioned along with the injectors, ever since its been very hard to run, an the MPG guage in the dash goes of it head when rev'd over 2k? boost doesnt seam to come into around 3k? an when you rev it hard on boost it pumps out black smoke, i check boost pipes no leaks ect, i was told to block off the small pipe that goes into EGR an see if it stop smoking, it didnt smoke as bad but still didnt fix the problem, iv had it plug in an nothing came up. has anyone any idea what could be wrong with it?
