My auto 2.8 A6's have always been slow to shift on cold mornings. It is part of the emissions that delay the shifting untilit warms up They were/are a 95 and 97 - I don't know about the newer ones.

 

yes my car is the 2.7 biturbo well i live in southern california so i dont think i need to warm up my car compared to living in the colder places in the u.s.

 

doesnt matter.. the point here is that your gradually warming up the Oil and Engine Temp as well as the turbos. Anyone on here or any other Audi Forum will tell you that this should be done!!! As I said earlier "you should always warm up your Audi because your turbos need to warm up. You also should limit your boost to not boosting at all if possible (meaning not going above 3k rpms) until the engine fully warms up and the oil temp warms also. Then after long rides let the car idle for about 3-5 mins to let your turbos cool down. Trust me you want to wake up a min earlier to warm up your car instead of paying out the butt for new turbos and labor install later on." You may not have to warm them up as long as me which is anywhere from 5-10 mins but you still should. But its your car do what you want.
