Does it have a JB4 tuning box on it? The fluctuating fuel gauge is a feature of it for displaying boost pressure. It connects to the CANBUS system so if not installed correctly can cause all sorts of issues.

I had the same and it turned out to be a broken ABS wire.

I have changed the Abs sensors?

Actually now you mention it so did I. Mine is an E82 so am not 100% sure the box is in the same place but I had a broken wire in the passenger side wheel arch that goes into a box hidden there.

My friend had the same warning lights and was a wheel speed sensor.

Mine was a broken wire on the car side not the sensor side it had broken just before the plug

Is there a part number you might remember for it or what is the part itself called.

No part number its part of the ABS loom that goes back to the ABS module. I cut the insulation back from the plug and i could see the broken cable

The two times our e93 freaked out in a similar way:

1. Dsc control unit
2. Alternator
