Revs pausing when foot to the floor (with video)
I mentioned this in this thread http://www.audi-sport.net/vb/a3-s3-sportback-8p-chassis/78089-help-needed-3-2q-dsg-hesitant-engine-%7E-2k-rpm.html but apparently it doesnt look like my problem is related so just thought I would get some opinions on my particular problem.
A picture paints a thousand words so here's a video (worth a million words?) of my problem. I have my foot to the floor for the duration of both of the short clips in this video, but as you can see the revs seem to just pause at some points. It feels like I have just put my foot on the clutch for a couple of seconds when it happens (and no I do not have my foot right near the clutch!). It only does it if I floor it though, if I just gently accelerate it doesnt matter what rev range I am at it will just get there nice and smoothly. Both of these clips were taken in 5th or 6th gear, cant remember which.
The second clip is the best example of what it does, when it stops just before 3K rpm in that clip. Its not normally as erratic as it was when I took that first clip.
Any ideas what could be causing this?
