Somerset (but I'm a Landanna)
I managed to clip a kerb while driving in Snowdonia at the weekend (Ok, I was looking at the scenery!) and the fuel gauge instantly stopped working. It just reads empty and I get the "Low fuel" warning.
It has failed in the past but then come back to life. This time it seems to be more permanent.
Someone said check for EPB fault codes as these can affect it, which I'm about to do, but can anyone else offer any suggestions?
Thanks
 
No codes from the EPB as such, but the instrumentation ECU gave the following 2 codes:

B100D - Steering column lock plausibility
U0128 - Lost Communication with Park Brake Control Module (PBCM)

I'm guessing the fault is related to the second code.
 
That would be very odd even though not impossibe when it comes to a D4 but the seder is connected directly to the BCM which manages the gauge, IMO it can be as simple as the sender or it's circuit to be at fault

I’ve just had exactly the same issue - how did you solve this Bukko?
