thanks!I don't think it's the actuator itself. After the first time it exceeds 2500 rpm, it behaves normally. so, like no boost for the bottom of 1st gear, but fine from then on, including the following times in 1st gear. odd.
engine temperature plays no role whatsoever. Stiction, eh? hm. occurs with age and bearing coking. I could probably verify that by giving the shaft a little spin by hand. But still, why? Fire it up, no boost till after 2500 first time. Then fine. Shut it off and immediately restart, try again, same thing. I'll see if I can find someone with a VAG and some know-how.Thx!
