BKN startet nicht | Posts 16+

Hello everyone,

A quick update. First of all, thank you for the tips, especially to Autoservice!
The engine is now starting normally. The cause was a loose ground cable connected to the MSG (Main System Module), which was located behind the coolant reservoir.

Now, the car is still having problems with the turbocharger boost pressure. The boost pressure is exceeding the limit (maximum pressure exceeds 2600 mbar at 3200 RPM), and we had to replace the wastegate control valve.
Now, the question is, is there a "default setting" for this?
I couldn't find that information in VCDS.

Thank you very much for your efforts!

Best regards.

P.S.: If needed or desired, more logs can be provided.

Okay, I'm ready. Please provide the German text you want me to translate.

Hello everyone,

Here's the solution to the problem described above.
There are several different control units for the turbos in the BKN.
Of course, it was incorrectly installed for the turbocharger that was fitted.

After replacing the control unit, everything works.

Thank you very much for your efforts!

SG Christian.
