DQ200 DSG Problems: Common Issues & Fixes

Hi there!
Perhaps someone here can help me.

I drive a Seat Altea XL 1.6 TDi CR with DSG (DQ200) manufactured in 2011.

I was driving on the highway today.
Without any prior unusual events, the display showed the error message: "ESP malfunction, visit a workshop," and the DSG (dual-clutch transmission) shifted into neutral.
I then pulled over to the shoulder of the road. I put the car in "P" (park) and turned off the engine.
Then I tried to restart it, but the display showed: "Please insert 'N' or 'P' to start."
I was in "P" (Park) and the gear shift was locked.
Could not shift into "N" (Neutral), "R" (Reverse), or "D" (Drive).
He put it in "P", so it can't be started.
I then called the roadside assistance service. They read the error codes from the car's computer. There are many errors, but none of them could be cleared.
With the emergency release, I was able to switch to "N" to tow the car off the highway.
At home, I then used VCDS to read the diagnostic data.
All the fuses are okay, including the ones in the engine compartment for the transmission control unit.
1.5 years ago, an actuator from the mechatronics system malfunctioned and was repaired by a German company.
Six months ago, the clutches were worn out and were replaced.
I think the mechatronics system is malfunctioning. What do you think?
Please delete the LOG file named "Papa" before starting the process.
The error message regarding the front axle wheel sensors appears because the car was towed using a wheel chock, which caused only the rear wheels to rotate.
File Papa2 is missing after the deletion attempt.
Thank you very much!

"That's actually good news; if there were mechanical issues, we would likely find something."
Of course, the transmission control unit could still be faulty, but a cable or connector problem is more likely.
Therefore, first check all cables, connectors, and fuses related to the transmission control unit!

Best regards, Rainer.

Thank you for the response!
