2000 A6 Quattro 4.2l won't start.
 

Alright car has power to all accessories ie windows radio lights sunroof. But no self check on warning lights or power to engine. Starter works through use of a remote starter. Found a black and yellow wire by the relay panel under the steering wheel,that was partially cut last time this happened. Checked the wire. Still no work. And one know what all the relays under the dash are for??

Trouble shot further...
 

Okay trouble shot further. Checked all the fuses to going to ecu, no power to any of them except for fuse 32 I get 4.40volts. Fuse 29 gets 0.01. Fuse 5 4.40 volts.

Fixed....
 

Ignition switch was worn. Too easy.
