A4 B8.5 Avant/Allroad - What’s inside the trunk side panel compartment?

[pinifarina]

Hi,

Yesterday my 2014 B8.5 Allroad 2.0 TFSI suddenly went crazy with several system failure warnings (tpms, parking brake, gearbox, pretty much every drive assistant system, and many more).
After a tow to the local workshop, they called and told me that the side compartment on the passenger side (the side with the cargo net, opposite to the one where amp is) was completely wet.

So, at this point I already know that I have somewhere a water drain issue (perhaps on the panoramic roof or gas cap?) that leaked water into that compartment.
I believe (might be wrong though) that the CCM, rearview camera module and a fuse box sit there, possibly among other electric stuff.

So my question is:
Exactly which electronic components are located in the trunk side compartment (passenger side)?

The purpose of my question is trying to get the full list of the components placed there and to simply assume that all of them are now dead and start a worst case scenario cost estimate to purchase all those components.

Many thanks.

Btw, I don't know if makes any difference, but my car is the European (german) version of the 2014 B8.5 Allroad 2.0 TFSI (224hp, 7 S-Tronic, CNCD).

Its one of the main control modules and fuse panels back there. I think BCM2. It has lighting, door locks, some audio systems. Basically all the stuff that is either entire care or rear end of the car.

This. Fuse panel, BCM2 and the parking brake module are back there. Your rear passenger sunroof drain is leaking down the D pillar.

Exactly I caught it early when I was looking for a MMI fault, the nipple at the sunroof was leaking and the water just followed the tube down

On mine the grease from the sunroof had clogged the drain tube and the water was pouring over the rail where it collects.
