Hello,

After the engine check light illuminated, I read a fault code of 9129, which indicates that the throttle valve is stuck in the closed position.
After the error is cleared, it reappears after a few hundred kilometers.
Now I've bought the intake manifold flap and the throttle valve.


Now I want to install them, but I can't find the option in the basic settings that allows me to calibrate them.


Where can I find this option on the VCDS software?

Hi,

How do you know that it needs to be calibrated?

Have you ever watched "Security Access"?

Autoscan?

Best regards, Rainer.

It clearly states on the packaging that it needs to be paired/configured.

It's also written on the Pierburg website.

When I navigate to the security code field, the security code that I would need to enter is not displayed, unlike with other control units.

I found a code, T5 T6 27971, and I entered it, and it was accepted.
But even then, I couldn't find anything in the basic settings.

For various applications, there is a specific device from the VAG group. The electric actuators for the turbocharger should also be affected.

Intake manifold flap & throttle valve: Pictures?


Autoscan?

The control elements of the turbocharger can be readjusted; this option is available.
Attached are the Autoscan results and images of the parts.
