[Gasoline Engine] A3 8L AGN: No throttle interruption

Hello!

My brother's 7/96 A3 is giving me a headache again. It's an AGN (1.8L inline-4 engine with 125 horsepower) and the problem is that the engine speed decreases very slowly when I take my foot off the accelerator. He does this while driving and also when stationary.
I've made several logs today, and, in my opinion, the throttle shut-off isn't working.
The logs were created by suddenly pressing the accelerator to full throttle and then immediately releasing it.

Here you can see how long it takes to reach the idle speed:

Does this thing have GRA?

If a short circuit occurs in the GRA-STG, the signal from the speed sensor is suppressed and no longer reaches the MSG. This can also produce similar effects.

The issue with the sender can also occur when an external radio source interferes with the signal.

Hello Roger!

Nö has no GRA. Whether the speed signal is still reaching the MSG, I will check. But only on the weekend, I won't be able to get my hands on it before then.
However, the problem also occurs when the system is running, so is the speed signal then not excluded?

Hello,

I'm having the exact same problem, has it been resolved???
I really need a solution!

Wie sieht es denn mit dem Kupplungsschalter unten am Pedal aus? Gibt es sowas beim Benziner? If so, does it work?

On the Polo 9N gasoline engine without a particulate filter, you can definitely find one. And a defect manifested exactly as described here...
