Howdy, I have an 1986 E24. I believe the SIGNIFICANT power drain is due to the OBC. I have purchased a used OBC for E24s 1987-1988. Any recommendations on how to remove the current and replace with the used unit ? I believe that the actions to remove it are different than what has to be followed on a 5 series.

Too simple to be true? I had a fellow member bring his OBC over to my car and simply unplug mine and plug his in to see if it would work. He was having some issues and thought it was the OBC. I think it may be that simple, but someone with more wrench time may want to comment.

E24: How do I replace my OBC John, Thanks again ! I would have never thought that I had to remove the center console to free up the part of the dash that has the OBC and radio. The pics on the Soviet web site are great. Jim 86 CSI 64 S-Type Jag 05 Cooper S
Well, I can have the one out of an E28 in under 5 minutes using only the phillips blade on a Victorinox pocket knife. But you coupe guys ... The best site I found was this Russian one. Good pictographic procedure showing you where all the screws are and how the panels fasten. Of course, this car had no power windows, as yours surely does, so plan on popping the switches out and disconnecting them, too. Given that this seems to be about a 2-hour job, I'd first be damn sure the OBC is the source of the drain (Pull the fuse for that circuit and check.). It is not known to be a common problem in the E28 where the unit and chassis are identical to the E24.
I don't know if this will be helpful to your current situation, but here are a couple of links you might find of interest if you are not aware of them: 635CSi electronic troubleshooting manual Big Coupe web site and forum. Regards,
