Hi. New to 545i ownership. I want to change ignition coils, but confused as to which type as I am seeing 2 types listed, either 8 straight items or 8 with a central 'lug.' am I just being thick? Any advice appreciated
They are for the rear, and are the B6's. I believe the B4 is pretty much a direct replacement for the OEM shock, so the B6 will be an upgrade. B8's are listed for the rear of the Touring, but oddly the part number is the same as the B6, so guessing this is a typo!
Alternator could be the culprit of the electrical gremlins,mine was very similar with the radio and I would also hear the gearbox message and tyre pressure loss on random occasions.
as for the power loss I had exactly that issue and it was a hole in one of the vac hoses
