Idle problems
Looking for suggestions. '96 AFC 2.8 with 106K miles. I'm having an idle problem. All appears normal at 750 - 800 RPM, then it suddenly falls off to 400 - 500 and recovers, or dies completely. Always restarts easily and runs well, but idle is unpredictable. No codes displayed in VAG COM

Re: Clean the idle control valve? Courtesy of Kris Hansen
Thanks for the reply. I had it out and all looks well. Ohms checked okay as well. I didn't pull the mounting flange for the valve. Any recommendation on cleaning the valve? What I could see of the plunger, it looked clean.

I'm not 12valve experienced. If the valve has been thoroughly cleaned and it still doesn't idle
properly, I'd surmise it was either a bad valve or perhaps you have a vacuum leak. Perhaps Kris or some other 12v owner will pop on with some advice. You can also post in the 12v forum ..<ul><li><a href="https://www.audiworld.com/forum/12v.html">https://www.audiworld.com/forum/12v.html</a</li></ul>

Found the tech site Kris has, and along with another input, all the guess work is gone. Will follow their suggestions and see what happens from there.

Re: No there is no idle control valve on the 1.8t. If you have an idle hunting problem it is more li
There "maybe" some confusion in terminology here, there is a Throttle Control Valve on the 1.8t which encompasses the Throttle Positioning Sensor.
Ultimately the throttle control valve on a 1.8t otherwise known as the throttle body is effectively an idle control valve among other things.
