Hi all.

I have a problem with the on board computer on my '92 325i convertible, on everything but the time and date screen I keep getting 'PPPP' on the display. In the owners hand book it just say's to refer to BMW. I had the same problem on my E34 530i but I can't remember how I fixed it. Anyone out there got any idea or know how to reset it?

I think if you disconnect, then reconnect the OBC with the ignition on, it can clear the PPPP fault code.

pull the power to the unit then plug it back in with the ignition on and it clears the problem .

or...

you can remove the instrument cluster (8 screws?) and pull the yellow OBC loom connector out from the back centre (and reconnect it)

make sure the OBC fault has cleared before you put the cluster back :D
