My OBC ('85 UK M535i) has been showing PPPP since I bought the car, time and date fns work OK but nothing else.
I'm really struggling to find the relay box for the OBC. I can find the bonger and there's a space next to it in the rack under the steering wheel that I suspect is for the module.
There's a space under it which has the UK/euro alarm (the one that needs a second door keyhole for the magnetic key!), I initially thought it was the relay module until I realised it had too many connectors.
Have tried tracing the wiring but to no avail as yet. I suspect the unit is missing completely.
Can anyone tel me where it should be, even those with left hand drive cars!
