Throttle body failure is not uncommon and can lead to shifting issues with the automatic transmission and other drivability concerns.

Volkswagen Cabrio Shifting/Drivability Issues Due to Throttle Body Failure
Volkswagen Cabrio Problem
Engine Affected: 2.0L 4 Cylinder
I bought my Cab 7 years ago. I'm from California, but when I moved to Maryland a few years ago, it seems that's when all my problems started. The last big expense was the new transmission. I thought that would have solved all the problems. But, after having the car in the garage all winter I went to drive it and it would not start. Had it towed to a mechanic, who got it started, but now I have other issues. It runs very rough and sluggish. Once I get it going faster, it seems to do a lot better. I was told this may be the throttle cable. Maybe it just needs to be cleaned? I hope this isn't going to cost a whole lot of money. I've put too much money into this car the last few years, and I know I can't get what I believe it's worth if I sell it. Maybe the throttle body just needs be cleaned and not replaced!!!??? I'm so frustrated because I can't get the car to pass emissions until this is repaired. I used to love my cute little car...I don't know what to do at this point. Any suggestions of what could be causing the rough idle? Also the engine light flashes on and off. Thanks for any help!
Engine is sluggish on take off and going up hills. Plan to replace throttle body soon. Will let you know what happens.
