The moonroof was very poorly designed/built. It clogs very easily and forces rain into the battery area. Other than that, it goes into the footwells and the comfort control module is beneath the drivers footwell. Soaking in water destroyed it. Now the windows don't go up or down. The moonroof refuses to open or shut. The car will not lock or unlock with the key. The car has sat now for too long and will no longer even turn on. The insurance company looked it all over and denied my claim. The vehicle has pretty much been totalled. Even after paying professionals to clear out the clog, there's still massive problems with it.

They have a design defect which allows water to get into the cabin via the moon roof. They also have an electrical motherboard under the drivers feet (comfort control module) that shorts out when it gets wet (which is easy when the rain comes in from the faulty moon roof). Now I cannot un/lock my doors, operate my windows open/closed, etc. And I believe it has negatively effected my ability for brake lights to function properly. This is a widespread issue, not just on mine. They were even class action sued for the same issue with a different year model (and settled out of court, but I was not an owner of the other car year). Please help. Thank you.

The car goes thro high oil consumption, around one qt every 400 miles. The car also burns oil every time accelerating on a small hill- smoke comes out from the exhaust system. Cannot expedite or drive regularly. It seems that it needs piston rings replacement which was defective in the beginning but the previous owner did not care about it. The car has 115.000 miles.

So I opened up the sunroof, took a long wire and started poking. I also removed the wheel arch and cleaned out the outlet. I poured a bucket of water thru and it came out of the bottom nicely. All well I thought. Today it rained for the first time since then, and I was very unpleasantly surprised to feel waterdrops dripping from the hood opening grip next to my feet. Since my car is always outside and not covered against the rain, I had to deal with it right away. I stripped the a pillar cover and saw it had serious water marks. Obviously the water had been dripping slowly for many months already. It just never got worse enough as you can see in the picture the green hose is the drain, and it has a brown stripe down the bottom from long time dripping. The leak seemed to come from all the way up to where it is connected to the sunroof drain pipe. I pulled it loose and the hose is fitted to the pipe with soft plastic connector. The connector slides over the pipe, but the hose is glued to it. Now the glue is exactly what caused the problem! the glue had gotten brittle and had cracked, it seems like Audi used the wrong glue for this hose. I cleaned it, glued it back together and poured another bucket of water thru, but now while the lining was still open and the hose fully exposed. No drip at all! I must say, this problem was a very nasty one, it really bugged me very much to get water in the car, especially because it can do so much damage. Attached is a picture where you see the roof airbag which was totally wet also. A picture where you see the green hose with the drip marks, and a picture which shows the left side of the dashboard with the fuse box exposed, if you look closely, you see the steel is rusted, since the sunroof water draining is a very wide spread Q7 problem I would advise all owners to check the fuse box.

I was driving on the highway and felt an extremely hot drop fall on top of my foot while wearing sandals. The pain was so bad I had to stop on the emergency lane to see what it was. There was a brown oily substance leaking from where the gas pedal is right on my foot. I had a pink mark after I cleaned off and kept driving. Got home about 15 minutes later and never felt it again. 2 days later the same thing happened again, also driving on the highway and this time I almost crashed because of the burning sensation on my foot. Once again it was the same oily substance. I went to my very trust worth mechanic and told me it was the heater core? immediately I knew it was expensive to fix. It's an 8 hour labor job. Took it to Audi and was told they have never heard of that happening on their cars, and seemed to blame me because maybe "I am not maintaining my car well" mean while I am on top of every little thing about that car. They want me to bring it for an inspection on this week, and they said they will have me speak with a service manager after. However in the mean time I am afraid to even drive it again. It was such an expensive car and to have to fix something like this should not be happening. Also the fact that my foot has now been burn twice, this needs to be considered a recall. I almost crashed the 2nd time around and could have injured myself and many others.
