I just experienced this error "
Electrical Networks failure: Stop!" on the way home form San Francisco to Oakland thankfully I was already over the bay bridge. After the car stopped I put on the hazards put on the break and turned the car off I had to do about 5 attempts to turn the car off, while still in the car I locked the car then re opened it with the key fob and pushed the start button the car came back to life and the dash read "READY" in green. I was then able to drive the car home. I called VW of Oakland and will drop it off tomorrow they said they don't give out loaners which
sucks :-(
Update: I decided to take it to the dealer today instead of waiting until tomorrow no point in wasting a day. The error "Electrical system failure: Stop!" happened again 3 times each time I was able to turn of the car wait and turn it back on again althought it drove it definitely felt wrong and I kept it under 25mph.
VW of Oakland said they have not seen this issue which is strange since one person here mentions taking their car to them with the same issue.....
