I just replaced my fuel pump as the original packed up. Everything seems ok but im having issues under acceleration. It seems that eveytime i put my foot down and hit 5k rpm, the car doesn't wanna rev any more? Now this only happens under full throttle. If i dont floor the peddle the the revs climb but obviously not so much power is being delievered? does anyone have any idea what could be causing this??

It does sound like it's fuel delivery related. Was is definintely a high pressure Z3M pump? as it's unique to the 3.2 as it runs at 5BAR, the rest of the Z3s are 3bar but I imagine they would both fit each other.
Did you replace the fuel filter also? Could be a blockage in that (not likely but worth a check).Last edited by c_w; 24-10-2012, 09:04 AM.
