B6 Audis have a design problem with their sunroof drains. When they clog up, unknown to you, the water will pool in passengers footwell area. It takes a while to notice this as a person, as there is 4-6" of foam padding between the metal floor of the car, and where you rest your feet . The TCM lives between these layers, and eventually, in the lake that will form, submerging your TCM -- leaving you with yet another reason to hate your Audi. This is early 2000's. Late 200 a8 models had I believe 30+ different "computers" living in the same over metal under foam situation.* I now have secondhand PTSD from reading this, and thinking about the Audi owners who have found out the hard way. Dead leaves caught in your sunroof can make your transmission flake out. I'm sure the owner's manual, on page 935, instructs you to ream out the drains with a pipe-cleaner every 5,000km so that your car can shift properly. The only word I can think of for this is..."perverted".
