Audi A4 B6 1.8T Avant

Throttle body not being aligned.
Getting the following error in VCDS:
17987 - Throttle Actuator (J338)
P1579 - 001 Adaptation Not Started

Gives same/similar error on the VW/Audi software at dealer.

Throttle Body will only aligned once this error is removed.
When ignition is turned to ON position the throttle body makes a scratching type of noise.
Have removed throttle body & cleaned with carb cleaner.
Still not working.
I have tested current on plug to throttle body.
- Pin #2 to Ground gives me recommended 5V.
- Pin #2 to #6 gives me recommended 5V.
Also done continuity of wires from plug to ECU & they check out fine.

Car starts but dies seconds after that. When unplugging the Mass Airflow Meter/Sensor car idles fine & can drive, but i'm guessing it will be heavier on fuel. ESP light stays on, but i'm guessing that's due to MAF being disconnected.

Any one have any ideas of what I can do to fix?

Morning, I am planning on doing a throttle body cleaning on my 06 A3. I was saw this video and found it helpful. in your case if you watch the video he makes mention of having to reset the throttle body. Its about 6 minutes into the video hope it helps. He does also say that disconnecting the the battery that can work. its about 8 minutes into the video.


Hope this helps
