Sorry a bit late to the party. I just noticed this thread.
No matter what people say about the problem not being Turbo Lag, after reading all the posts in this thread, there is no doubt in my mind the description of Turbo Lag fits the scenario for many people.
If people care to look on other forums, it happens a lot with the Audi Q5 TFSI (252 bhp UK version) and by being in Sport mode the Lag disappears. Many other 4 cylinder very efficient Gasoline (Petrol)Turbo engines have this problem. So the solution adopted was when waiting to join the traffic flow we always changed to Sport mode. This mapping appears to keep the turbo spinning fast enough to make the throttle pedal more responsive for a quick getaway. Once up to speed in traffic, we changed back to Eco pro/comfort.
