Electrical issues with 2008 BMW 520d manual

Smurph
in BMW 5 Series Forum

Featured Replies

Hi,

I was wondering if someone is able to help on this issue...

So I have a 2008 520d which decided to have some electrical issues occur, I had a message pop up to say "electrical malfunction car no longer drivable "

The instrument cluster doesn't light up and nothing works on it, the radio doesn't work, the central locking has now failed on it. The indicators still work alongside the lights but nothing shows up on the dash. The fans now don't work. And the horn doesn't work.

The windows still work also but the horn and window wipers has stopped.

The engine starts and the car still drives nicely, just no idea on speed or fuel left.

I've checked all the fuses and no issues with them, I've plugged in a diagnostics machine and it hasn't shown anything.

Has anyone else experienced this?

    Hi Tegan

    Welcome to the Forum

    My guess would be an issue with either the FCM (Footwell Control Module) or the Junction Box Module. To be sure you will need a diagnostic scan by someone or a Garage that has BMW capable software Autologic, Foxwell, i Carsoft or best BMW ISTA/INPA. There was a recall for the main power feed to the fuse box has that been done ? Worth checking.

    A BMW Dealer will tell you you need genuine new parts and only they can program them that is not so.

    Good Luck
