Ben sorted it all now and it starts fine. In addition I got a full service so spark plugs, pollen, air filter, cambelt, rollers, tensioner, pump, but stupid Audi sent the wrong pads so all front and rear discs and pads will be changed next week by Ben, all genuine Audi parts too. +++

Dead A8 & S8
 

So what did Ben find? Was it a combination of many issues or just to the key lock mechanics?:rolleyes:

Some failed wiring or something, he will probably be along later to tell us. +++
