Hi all,

My car - Audi A8 (2004) 3.0TDI

I wonder if someone is able to advise how serious Local Databus failure is? I have run VAG-COM scan and the report shows the following fault:

The low voltage reading did seem to go after a battery re-charge (as advised by "A8TECH" but reappears now and again so not sure if this is somehow related to the databus fault.

If anoyone has any ideas your comments would be very much appreciated, as i cannot seem to get to the bottom of the fault. The car seems to drive normally, but some times the MMI shuts off when starting the car.

thanks again for any help/comments to assist.
