NoVA_A6

My dealer just cleaned the throttle body and I haven't had the problem since, hopefully this takes care of it.
One thing I noticed is faster acceleration and better throttle response.

How many miles do you have on your car? I used to do this on my last car but never thought to check it with my new C6.

37K, I bought it used and there was a little lag when stepping on the gas, I though that's just how it ran. Now it's like a new car, FAST off the line!
I hope it took care ove the WOT issue, time will tell.

April

the throttle body when temps were very low (think 0F or -18C). Prolonged driving at one speed would bring it out. No issues with the 3.0, 2.7t, or 4.2.

the floor mat stuck under the accelerator every time. All the fail safes for the drive by wire will put the throttle plates closed. Not saying that its not possible but according to most manuals its almost impossible for the throttle to stick open due to a malfunction

allowing you to safely stop the car. Just curious, did this happen, or did the power remain at full throttle while you braked to a stop? If it remained wide open then there is in fact, a problem with the fuel control. If the power dropped back, the problem may be elsewhere.

Yes, it was the mat stuck, seems a bit of a problem from what I've seen here.

He could have made the "sinking" of Audi his final story on 60 Minutes! Glad it worked out fairly simply.

I have an '08 A6 which i just finished breaking in.. The other day i floored the gas to pass, and it remained in downshift mode near redline even after i released the gas, as though it got stuck in that gear. The car may have been in Sport mode, so i figured it may have just been a delayed upshift, but it's a freaky thing because i didn't intend for the car to stay in that low gear at high RPMs.
