Screen Flickering - Corrosion to Sirius XM, Aux modules
Hi all,
Long time since I've posted. I had a leak around the windshield and shortly thereafter had faults with the touch screen flickering in and out. I replaced the battery which didn't resolve the issue. I then took the front seat up (E12 socket) to go through the modules underneath. They are the:
-Bluetooth control module
-Sirius XM module
-Aux multimedia interface module
The Bluetooth module looks fine. I inspected the board and there were no signs of corrosion. The others though (metal boxes) are heavily corroded. See photos.
I don't want/need any of these systems. My question is how would I delete them to resolve my screen flickering?
I have not experienced this fault but there are YouTube videos on this.
You can by a MOST jumper cable that just plugs into the module you are checking to see if your screen returns.
Seems to be relatively common from water ingress killing these modules. I have not had this issue on my two SV8's
Cables available on ebay and amazon.
sunroof drains, windshield, cabin air water deflector are the big 3
left side is just a nuisance. when right side is flooded you take out the tpms the adcm and the seat climate controller, crashes hs-can and ms-can which is not fun

Water was coming in from a loose ran tray/plastics around windshield. Prior to that it was plugged sunroof drain which lead to water on passenger side. I removed both BCMs to inspect for water damage, they both appeared fine. I have a host of other issues (TPMS always on the fritz). What are HS/MS can?
Ordered the fiber optic most loop to find out which module is bad. Will report back.
Edit - I now see that the Adaptive Dynamics and TPMS modules are under passenger seat... Neither are working right now so I will be removing the passenger seat as well to inspect. Harsh reminder to clean your sunroof drains.
