Finally I desided to change the Audi's original c-casetteplayer to little modernlike dvd-player, and what happend, I connected the new player like is should expect the power from the ign key which I took from blue wire where I found enough over 10 Volts to turn the radio on and.. all seemd to b fine as far as I decided to take a little ride and turned the driving lights on.. then BAM and all dashpanel lights blackouted no smell no nothing more than just a snap.. all meters works fine and even the boardcomputer display is fine.
All dash panel bulbs are ok as I measured and the dimmer for those is ok.. Can anyone help me out??
Fault that founded with diagnostic said
00532 - Supply Voltage B+
07-10 - Signal too Low - Intermittent
but after clearing faults it didn't came back.
I measured the fuses and all were ok, is there more fuses somewhere than at the side of dash at drivers side?
And all other lights seems to be just fine, except the long range lights but those didn't work even before this.
