2016 Q70L, flood car - got most of it working, but still trying to solve a few issues:

Backup camera doesn't work - found the computer in the trunk area, all corroded, so will get another one and hopefully that will solve the issue.

AFS light blinks constantly - where is the AFS module/computer located? I have a feeling that it's corroded/fried.

Both front seats do not heat up or cool.. The switches turn on briefly, then turn off. Any ideas?

I would appreciate any tips/suggestions on how to get these issues solved. Thanks.

I'm not aware of any threads regarding computer modules. Newer cars can have as many as 50 different CPU's and miles of wires with countless connectors and harnesses.
Even worse, these CPU's are interconnected and dependant on each other so that a warning light for ABS may be the result of a failed communication with a completely different CPU not related to ABS at all, but due to a failed communication, it results in an ABS light while the actual ABS unit itself is actually fine. In a flood car, you can be chasing electric gremlins forever. Might be worth your while to purchase one of those high-tech 'dealer level' scan tools that reads errors in real time to help you chase down the actual cause of each glitch.

Man, wouldn't it be nice to have such information in a central location!
I have done it for other cars I own, (link 1) and (link 2), but it seemed like the kind of information most people didn't really care for.

My advice would be to refer to the service manual located here - https://nicoclub.com/FSM/Q70/2016%20Q70/2016%20Q70/
Start with the pdf file named IDX. It is the index and will tell you the file name of where everything else is located. The service manual not only shows you the location of all the modules, but also what their spec is and how to troubleshoot them.
It is a lot of work on a normal day, and will be even more interesting with the nature of your project, but it is a very good resource.

For the climate controlled seats, here is a thread that could lead you in the right direction - post6787918.html?#p6787986

Good luck, and keep us updated.

Thanks for this awesome info. The service manual helps a lot, especially knowing where the index is.. I'll keep it handy so I can refer to it for other issues..

Regarding my situation, I'm still trying to resolve the various issues. Over the weekend, I pulled out the driver's seat and checked the connections underneath, all seemed ok (although the frame shows some rusting). The motor that moves the seat up and down is backwards - when I pull up on the switch, the seat goes DOWN, and vice versa.

The AFS light keeps blinking, and I still haven't found the AFS module - based on the service manual, it'll be in the center console somewhere, so I'll try that.

Yes, flood cars are a beast to figure out, and it's hit or miss. I've bought flood cars that had not seen a drop of water, and others that were flooded to the level of the steering wheel (like this Q70).

That being said, I'm limited by not having a computer that the dealer does, to go hand in hand with the diagnostic methods and procedures..
