I've been experiencing some weird acceleration lately. If I get on the pedal to pass someone the car will keep accelerating after I release the pedal. It's not leveling out or coasting but continues to accelerate faster and the pedal will continue to go down on its own. Pretty scary the first time it happened as I was trying to merge into tight traffic. I was like WTF. It seems to continue surging for a few seconds. If I hit the brakes it will stop surging immediately. The other day I was in a tunnel and decided to blip the throttle. I was at about 3k and changed to neutral and i hit the throttle slightly just so I could hear it rev...but then it jumped all the way to 8K and was there for about a second or two. Didn't make any sense...I barely touched the throttle. The pedal did not continue to depress on its on when this happened. It released right away so I didn't expect it to keep revving. Wasn't until I got more surging today did I realize it was probably all related.
Definitely not a floor mat issue. The accelerator is not really stuck, but more like accelerating on its own. Seems like a DBW issue. It feels similar too when you're on cruise control and the accelerator depresses when you're going up a hill to maintain speed.
This is totally screwing up my throttle response feedback.
Search and found some similar reports, but no solutions. Anyone have ideas or know if there is anything I can VAG-Com? Gonna do a throttle body adaptation when I get home.
