Error Code 2ADF??

Has anyone had this code and how did you resolve it?

2ADF : Idle Running Control, Speed

I got that code after changing the front rotors/pads. I cleared it and hasn't come back on since.

I've seen that code caused by a vacccum leak causing a slightly elevated idle speed. The DME tries to reduce the rpm unsuccessfully and triggers that code.

I'm assuming the code is the same if the idle speed is lower as well? I have that problem where idle is under 650 and it vibrates on idle. Still haven't been able to figure it out (unless I'm looking in the wrong areas).

Thanks Shiv, I will check the Vaccuum hoses. I am guessing a good place to start is around the Canisters that control the wastegate?

NOTE: the car runs fine.

UPDATE: Vacuum leak discovered at Rear Turbo inlet pipe. When the dealer replaced my turbos, they did not get the little bracket set properly to hold the inlet pipe on the turbo and it slowly worked itself off. My indy shop smoke tested, found the leak, and the error code has yet to return.
