Default Clutch makes clunk on first engagement after cold start

I recently got a 2002 A4 3.0 Quattro,
When I either back up, or pull forward in 1st (or reverse) when the car is cold, the clutch makes this funny clunk when it's nearly all the way released.

When I start backing up, with the clutch pushed 3\4 to halfway, in... it's normal feeling, but when I get to like 1\4- 1\8th pushed in, it makes a noise. In addition to the noise I can feel a sort of clunk. Often times, I backup, and never fully release the clutch, then throw it in 1st, and when I get close to releasing it in 1st, I hear\feel it then.

Only does it once per cold start - not on warm starts or anything like that.

While this does not worry me, I want to know why it does this - i've not had a car do this before.
Is this normal? Does yours do this too?
I drove 1.8T and didn't notice it.

Thanks
Rob

is the clunk from the rear of the car?

Tranny Fluid is most likely cold and does not provide sufficient lubrication until it is warm. I would check your fluid to see if its low and inspect your clutch plates.

After driving it again, it sounded like a Crunch. I will listen more carefully in the morning and see if I can tell where it is coming from. It is very reporducable, it happenes every morning without fail.

Brake pads - sounds like that could be it. Oddly enough, I tried to feel more carefully, and I felt it in the gas pedal more than the clutch. Also, by engaging extra slow, I was able to make go crunch after it was fully in gear (1st), it made the crunch when I accelerated. Also, it's not just when cold -- I got it to do it after the car was sitting for about 5 min. Perhaps it's some sort of "test" that runs every time you start moving?

Thanks
Rob
