My A6 has developed an electrical fault. It suddenly cuts out for no reason and stops. Diagnostic tools will not work because the whole system goes down. Has anyone experienced this fault? Is there a quick fix!

If The Vag-Com is not working when connected it may be signs that your cars ECU is on its way out???

Have you had an Audi dealer Vag-com it or independant ??

Independant garage is investigating. I am no expert what is a ECU. I guess electrical central unit! Is that correct?

Yes its the cars electronic brain(computer) that controls pretty much everything electrical...

What was the problem with yours?

Audi cut out

It turned out that my car had been "chipped" and eventually had to have a new computer!! Expensive but not something I could have known when I bought the car
