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

Dave

      X3 2.0 automatic

      hi , I had very similar problem a while back, and after a lot of testing with vista, it turned out to be a front R/H wheel , speed/wheel sensor. when it all was happing lots of codes were coming up gearbox, diff front and back, transever box,plus many more, didn't look good, but there was one code that repeatedly came up at the top of the list, at this point it was becoming undriveable ,it just didn't seem that a wheel sensor could cause all these codes. So I went got two wheel speed sensor, replaced driver side front, the problem never came back, the sensor controls so many systems ,cleared all codes, happy days, I could have pulled the car apart for nothing, and got nowhere, except an empty wallet. hope this helps you or someone.

      105C thermostat replacement

      As I understand the wiring diagrams and operation Item 9 on the thermostat housing is the sensor which sends its signal to the ECU for interpretation with information from the map sensor. Information from item 12 (1st drawing ) is also used to provide average temp across the cooling system. As far as I am aware the Thermostst is independent of the sensors and operated by expanding wax material internally

      BMW 318i boot locked can’t get into

      Errr not clear here Donald Plastic "L's" with short rubber hoses ??? Distilled water/Ionised water should only be used in an old style lead acid battery. The Rad and engine coolining system should be filled with the correct coolant mix to prevent cavitation and the danger of freezing in low temps. Coolant should be part of the cars regular maintenance and changed every 3 years or so. At that time all hoses and connectors should be inspected and changed where necessary to keep everything in tip top condition. Changing parts can cause as many problems as you may think your solving
