I've had my A4 for about a month now and I had a couple questions about it since I've never owned a vehicle with a turbo before, and never a car like this (previously drove a Dodge Dakota) If anyone can give me some info on these it would be appreciated.

1) Trouble shifting into 1st gear (manual) very very rarely, only when at a stop. When I try to shift into first it just won't go into gear. I have to either move the shifter back down to neutral and up again, or let off the clutch, reapply and then shift. All other gears are fine, and very smooth. And this only happens rarely, although when it does, since im usually at a light, its a bit of a surprise. Is this something I should take it in for?

2) Driving with the window down and next to a building or something that will reflect sound, when I step on it the turbo sounds like it is sputtering/fluttering, although power is smooth and its not noticeable at all with windows up. Normal?

3) Harder to describe this one, when i first start the car up and I back out of my parking spot and am and then go forward towards the street, the revs/engine doesn't sound as smooth as once i'm driving. Also I know there is the "click" when the door locks engage at 15km/hr, but i also seem to hear another metallic kinda click before/after that. Far as I can tell only happens when the car had been sitting for awhile, does that have something to do with quattro or am i imagining it? I know I'm not running over anything in the parking lot and I assume it's just because the car is still warming up.

EDIT: So as not to give the impression I am displeased with the car, I love it. I've already put 1600km on it since I picked it up mid April, and I don't regret it one bit :P
