Seems like the tumbler. Have you contacted any Audi dealerships to see if they’ve seen this before? This seems like the type of problem that is so unique a tech would recognize the issue if he’d seen it before. Maybe ask Jimmybones on AZ?
Let’s get this figured out. It’s been getting really bad recently. See video:

The miss-fire makes me ;D
^hahaha, holy shit, that last video really shows it. Send that shit to AoA!
Joe, that has to be somthing electrical installed in the car.
Check your head unit, and since you got the car used, check the wireing going to the cluch peddle.
My 05 Denali will do the same thing, but I also have revelco installed in it. I pop fuses in the fucking truck, AC/ heater controls, but my setup isn’t even connected to them.
try turning the car off with the key in the ignition…wait a sec…then remove
bet it doesn’t happen (the running on thing) when you do it that way. bet a Coke. Seems like you’re flicking the key out of a 8 year old cars weakened ignition switch/lock
then when it doesn’t run on, and i’ve cured your ‘issue’, will you please stop bumping this boring ass thread? 
Yeah I do have an aftermarket stereo but it has been doing this since I got the car. At that time it had the stock radio
You owe me a coke motherfucker

SHIT
^^^LOL. You guys are hilarious.
Joe check out this thread: http://forums.fourtitude.com/showthread.php?5371346-Still-runs-with-key-out-VCDS-gives-little-clue
Seems similar to what you’re going through
Great find, I hope this solves Joe’s problem.
Haha, how funny would it be if it was just that one screw causing this issue.
Hopefully that solves it, good luck Joe.
Thanks apat, I will check that as soon as I get home. Wow if that’s the problem that would be awesome.
Thanks guys
Thats 2 coke bets you have lost now…
Did it solve the issue Joe
Haven’t had a chance to look at it. Busy with work/school. Monday I’ll take a look
If it fixes it Saki owes me 3 cokes… ;D
at this rate, Saki better have shares in Coke!!
UPDATE.
Figured out that my aftermarket head uni or my valentine 1 must have been causing the issue. Removed the radar detector and put the stock radio back in and the issue is gone. Weird
figures. This is why dealers deny warranty coverage for everything when you modify anything.
Looks like I won a coke!
I used to have the exact same problem. Dealer had to reprogram the ECU. This eliminated the issue.
find a priest and exorcise the demons. that should always be the first step.
