I'm a new member and new to forums too so hopefully I can get some support from fellow BMW fans and owners.
I have a 2005 318Ci for 11 months. Its been towed twice with the engine light on and really bad misfire. In between those events misfires happen but it rights itself. The revs also drop from time to time and a judder or vibration happens on take off.
I had a 1996 E34 before this which was a dream!!!!
History - One coil was said to be faulty and changed by BMW
The second time another faulty coil - BMW said they only replaced one Bosch with the new Bremi and they should have replaced all 4 the first time with the new Bremi so I though problem solved. However problem still occurs and its becoming most upsetting!! I brought it back as it still under one year BMW warranty and guess what. . . . anoher faulty coil changed. At this stage I asked them to explore some other cause that resuts in coils going bad but the garage seems sure all is ok....... has anyone else had this problem??
Sorry for the long winded question.
All the best from the cold Ireland
