Trying to do a TBA on my 2.0l AQY
« on: 12 July 2010, 15:26 »
As above, did a scan with VAGCOM.

Currently getting the error codes:

  17987/P1579/005497 - Throttle Actuator (J338): Adaptation Not Started

Possible Symptoms
    * Malfunction Indicator Light (MIL) active

Possible Causes
    * Throttle Body Alignment (TBA) not performed

Possible Solutions
    * Perform Throttle Body Alignment (TBA)



  17973/P1565/005477 - Throttle Actuator (J338): Lower Stop not Reached

Possible Symptoms
    * Malfunction Indicator Light (MIL) active

Possible Causes
    * Throttle Actuator (J338) dirty (carbonized)
    * Throttle Actuator (J338) faulty

Possible Solutions
    * Check/Clean Throttle Actuator (J338)


I have tried following this guide:

(These are engines with a physical cable between the accelerator and the throttle, but WITHOUT an ISV.)

Turn the key on but do not start the car.

    * [Select]
    * [01 - Engine]
    * [Measuring Blocks - 08]

Enter Group 098 (Note: Some SIMOS or Marelli ECU's use Group 001 such as ADY & AEE engines)

    * [Go!]
    * [Switch to basic settings]

Once you do this you will see the top right display say ADP RUN. The TB adaptation is being done as soon as you switch to basic settings. You will see the values change and hear the TB cycle for the first few seconds then it will stop. Leave it in Basic Settings for about 30 seconds.

    * Click the [Switch to Meas. Blocks] button and you're all set.

Be sure not to touch the accelerator and make sure the engine is NOT running when you do this!

In regards to the text highlighted in red, I cannot see anything that says ADP run.


Any ideas guys?

Also when my throttle is fully depressed Its only about 85% open

have you cleaned it? butterfly is still probably out of tolerance and preventing a TBA

also vagcom might not show the full info if it's a cracked version or has no label file for your ecu type, but it's odd that you don't get the adp run or even adp err text showing :undecided:
