Hello everyone,

I'm new to this forum and was hoping to get some help. I have a 2018 Q5. I gave it a wash yesterday and when I started it today, the blind spot monitoring system, parking sensors, and right reverse light is not working. I'm thinking water might have entered the parking control module and wanted to see. However, I can't seem to find where it is. I opened the compartment in the rear right but couldn't find anything resembling the parking control module. I've spent some time on here using the search function but didn't really come across anything for 2018+ Q5's. Don't know if I'm searching for the wrong keywords or what. I did find this post below but its from the previous generation and it seems the location is different ( I've included the link below). Any help would be appreciated.

Never mind. I finally found it. Turns out there's another compartment on the rear left that has the module.

If there's water in that area, you should look up "Sunroof drain issue" in this forum - It can really mess up the vehicle since the BCM is located in that rear-left compartment.

Thanks. Seems dry when I felt around. So will be taking it to the mechanic to get it checked.

Wanted to give an update. Turned out an animal decided to chew some wiring by the bumper light. My mechanic reattached them and all is well.
