Schematic needed

Hi all,
I have a 2008 Audi Q7 that has the Bang & Olufsen system in it. I recently has an amp failure in the rear passenger/cargo compartment due to water ingress. (Sunroof drains) So I opened the amp and cleaned up the PCB, still doesn't work. Under significant magnification I can see a few of the VIAs on the PCB have corroded to the point that connection may have been lost to the internal traces. It is too difficult to see the internal traces, so I need a schematic/diagram for the PCB to attempt a repair.

I have called B&O and they referred me to Audi. I haven't called Audi yet, but I can imagine the response I'm going to get from them regarding internal amplifier schematics.

So, I'm here. If anyone has any ideas as to where to look next, please let me know, thanks.

Audi part #: 4L0 035 466

Numbers on PCB:

3 120 143 019
H06 1000
