My A6QW does not have the Tiptronic, but the regular 4-speed automatic. This is *exactly* how I was told to drive it: stay in 3rd around town, leave 4th for 50+MPH cruising. I do it a lot, but don't have many miles on the car (4K so far). I suspect the only problem will be a slight lowering of mileage. I put 200+K miles on standards driven routinely at 3K+RPM, no problems at all with the engines or trannies. In a hopefully-unrelated question, I've noticed that when I leave it in Drive, if I am "coasting" along with little power, when the 3rd-4th shift happens, the car sometimes selects neutral for between 1/2 second and 5 seconds. Then it drops into 4th with a slight shudder (1/2 second) or a huge KER--THUNK!!!! (5 seconds) given the high revs from being in neutral. Anyone else with a slushbox seen this? -- Andrew L.
