2004 Audi A6 3.0L - Symphony II radio
Problem started with the radio shutting off every few hours then progressed until it became seconds between power losses. After some troubleshooting it seems to be that I am getting some extra resistance in the circuit. 11.5v with the plug out (K & alarm gnd clipped so only + & - now) and only around 5v in. Suspect would appear to be the relay though I cannot locate a relay diagram without a hefty purchase. Can anybody point me in the right direction?
I ended up taking power from what I believe is the horn relay for both the head unit and the rear amp. Both working well now. After some digging I found a diagram for what appears to be the correct panel with the radio relay.
Aux Relay Panel 1 is 17 (shown in first pic). Looks like it's under the hood.
Central Electric Panel is 16, under the instrument cluster, and where I stole power from.
