Suspicious Battery Drain in Audi Audio / DashCams / Electronics / Security Posted June 22, 2020 I had similar problem on my 2004 B6 S4. Turned out to be faulty radio head unit internals. Try removing the fuse for the radio - preferably while monitoring current (drain) on the battery with a multimeter.
