Hi lads, new to Audis here. We have a 2008 b8 a4 s-line 2.0tdi caga. Few lights on dash including: ABS, glow plugs, engine management, traction control.

plugged it in and these codes appeared:
U012100 - Lost communication with abs control module
U1015- Brake control mondule no communication
01316- Brake control module

Have tried changing the abs pump/module and no luck, do these need to be programmed to the car?

Speedometer not working and fuel guage sporadic.

Any help seriously appreciated🙏

It sounds like the instrument cluster is faulty, a not uncommon problem. It can be repaired by a few companies if you remove it from the car and post it to them, or you can pay a great deal more at Audi.

Any comment on this Zoe, or have we both wasted our times putting fingers to keyboard?

To be honest Cliff, I think we have both wasted our time pal 

Agreed, which I'll bear in mind for the future.
