Every morning when I start car, I wait at least 5min. before start to drive it. During that time car is in “P” parking position, and engine sound fine. But, when I start to drive, first 15km car don’t go well. Engine, choke and shake, without power. If I stop (on traffic light- semaphore) and transmition is in “D” drive position, it’s jig and vibrate… After some ride (about 15km) car start to work just fine, engine have it’s power again and car don’t shake and vibrate any more… Problem will be repeat if car stand more then few hours and cool down. I need help; does anyone know what can be problem and how to fix it? My apology, because poor English.

The gearbox is very sensitiv regarding too less or too much oil. You need the stick to check it at the pipe coming up below the brakefluid reservoir. But when you do so the gearbox must be warm, so drive at least 20km before! Do not just fill up, first measure!

I change my oil filter and I regularly check for level of oil in transmission (when engine is warm and running). I think that my transmission work fine, I didn’t notice any problem with shifting and it’s seems that all three modes ( “S”, “E” and “M”) work fine. I felt different in shifting between “E” and “S” mode, but I still don’t know what “M” mode is? I must admit that I’m not experience with automatic transmission. I check on many forums abut automatic transmission and problems that can exist. But I didn’t find any tips abut, maybe some basic rules of driving car with automatic transmission, because I’m not shore that I drive this car in good stile. I also notice, that often when I start engine it’s shut down and after immediate restart it’s work fine (this happened same with cold or worm engine), and I already check and change main air valve (on front side of engine). I check computer but it didn’t show any error. What to do next? Is there chance that “air volume” sensor (I don’t know name of that sensor in English)… on top of intake, after air filter… is bad? And how car go perfect warm and so bad cold (Outdoor temperature here is between 0C and 5C)? Sorry for bothering you, and thanks for all response.

I would try this first, maybe you`ll receive a clue as to wich sensor is misbehaving. You find details as to how this works on the SJM home page. VW/Audi dealers usually perform this service for free or nominal cost, if you happen to have one nearby.

I have a standard (5 speed) version) and on cold starts it runs very rough for about 5 minutes until slightly warm and then it runs perfect. (almost like it was running on 4 or 5 cylinders). To me it sounds like the distributor cap or maybe even the spark plug wires ...which would maybe explain why this is not being picked up by the diagnostic system. Anyone else out there that has had this problem PLEASE HELP!
