Hi please help me, I have a Audi A6 1999, 2.8 Quattro, I have two problems, my sunroof work pretty good, when is a hot day and my car is outside, but when my car is in the garage, doesn't work and when I leave my car outside and it is a hot day, sunny day, I can use it well, somebody knows about this?. My other problem is I get a check engine code P1338, I read this is about camshaft, but the weird thing is when I get the light and the beep for gas, after that I start the car again, I get the check engine light on, whrn I put gas and I start the car couple times, then disappears, please help and thanks in advance.
