T5 GRA spinnt

Unfortunately, I haven't had a chance to investigate the cause yet.
Currently, the T5 has developed a new symptom: the GRA (presumably a system or component) is malfunctioning.

Manchmal lässt sie sich gar nicht einschalten. Ich dachte, das läge daran, dass der Motor aufgrund des Unterdruckproblems in den Notlauf geht. Doch dann ließ sich der Tempomat wieder aktivieren. Dastrange:

When you turn on the left blinker, it turns off!

Can someone explain this to me?
Could it be that the entire electrical system is malfunctioning due to the faulty air quality sensor?

Here's the log:

Before you drive much further as described above, please check the intercooler system. This should be relatively quick and will help extend the lifespan of your vehicle.

GRA: Use VCDS to check all the switch positions. Possible faults include a defective steering column control stalk or wiring problems. These two errors are unrelated.

In that case, you can be almost 99.9% sure that the lever is broken. It's not uncommon...

I have moved these posts from the original thread because they are not related to it. We would appreciate any feedback you may have on our answers and suggestions.

Hi Matthias,

Thank you for your suggestions!
Here are some questions I have regarding that:

Charge air duct: This refers to the supply of air from the turbocharger onwards, correct?
Then there was also talk about the vacuum system: From the tandem pump, which lines should I check?

"Check switch positions with VCDS": Are you referring to actuator diagnosis from the turn signal lever? I'll be able to find that...

Oops... But definitely better than a defective control unit!

Great, thank you very much!
