This is might sound a bit stupid but these probelms with rough running to serious failure all come down to Fuel Injectors and or Coils, isn't it about time a new part was designed rather than replacing like for like??????
Does anybody know exactly which component has the fault and why!?????
This thread goes back a long time, there must be some advancement in what is exactly causing the issue?
Having said all that, the sun is out and my 320i is running smooth as anything, the occasional blip has dissapeared
