HELP
 
The AMP is dead, so very little to help on this one, you can either replace the AMP and get component protect removed or get your AMP repaired https://boserepairexperts.eu/repair-models/
thanks but the only problem y have is that i live in argentina and a new one here costs like $600 and if i send it to repair its probably not passing the controls on the border :(
 
There is no other option, a dead amp is a dead amp! It's either replace or repair but the repair requires specialist knowledge & tools to fix the circuit board.

hey do you know if the board has to be the one that comes whith the car or can be replaced and its a put and go?
 
No the board has component protection, and would need to be removed from an Audi dealer.
