Bit of history first.
I had my car serviced about 1800mi ago (2 months) and and at that service they replaced the PCV.
About 2 weeks after that service, I started noticing a slight intermittant flat spot at 2000rpm. I don't know if flat spot is the correct term for this, but basically if I had lifted off for a few seconds then reapplied throttle, nothing would happen for about 1/2 a second then the car would suddenly come alive and I could accelerate again. Have been suspecting it was the multitronic, but I took it back to Audi and they keep telling me there is nothing wrong with the car, even after I showed them the flat spot. (It seems their attitude is if there is no error from the computer, there is nothing wrong)
This morning when I got to work, I put my car into Park and noticed that the revs rose to about 1100-1200rpm and sort of hovered around there.
I revved to 2000rpm, the revs would drop back down to 800rpm for a second or two and then rose back ro 1100rpm.
I revved to 2000rpm again and the revs dropped to 800rpm, but idle was very lumpy...the whole car was shaking slightly, then the idle became smooth, and then after a second or so, the revs were hovering between 1100 and 1200rpm.
Didn't do this when I was leaving home and the engine was cold.
I'll go do a VCDS scan during lunch to see what errors pop up.
I suspect the idle issue is PCV, but could it also be creating a flat spot at 2000rpm?
Maybe the car is just trying to tell me to get a younger model...perhaps something with an 'S' in the name
