Question about 2001 BMW 325
I can't locate a ground prblem in my 325i. The check engine lift flickers on and off - and the headlights will flicker at the same time. The engine also runs rough - seeming to miss with each flash. Would this be a grounding problem and if so, where should I check?
First point of call is the alternator, BMW decided to use Valeo alternators on 1992 - 94 cars, these do not have replaceable brush and regulator packs like the Bosch.
You will more than likely be able to pick up a good refurbished unit on E-Bay for half the price of the local motor factors or main dealer.
Make yourself familiar with the routing of the drive belt and the spring/hydraulic tensioner before attempting the job.
Apply copious amounts of WD40 to the alternator mounting bolts days before you attempt the job, as they are frequently seized.
Disconnect the battery before you get anywhere near the alternator with a spanner.
Removing the Alternator cooling duct, air filter box and the airflow meter make life so much easier! (you'll see what I mean) :)
Apply grease to the threads of the bolts on refitting.
