It lies behind the pocket on the passenger side of the trunk (hidden behind plastic in this picture) and has three cables (circled) going into it. The grey connector came disconnected in my new to me 14 B8.5. When I try to turn off the soundaktor via VCDS or do an auto scan, the A9 (structure borne something) module is unreachable and I'm wondering if that could be the cause.
Also, is the coiled cable OEM? I'm guessing not, but I can't see where it comes from or goes to. The car came with an aftermarket sub, but it is connected to the stock wiring.
