How did you figure out it was the control unit? Did the error code specifically point to that?

The error code indicated a general communication fault on the data link. The mechanic suspected a faulty connection and, after checking the cables and plugs to the control module, found a defective one. I'd suggest taking it to a workshop; they can pinpoint the exact cause.

Alright, I'll get it to a workshop ASAP and have them check the control unit connections. It actually was a defective plug. Repair cost was around 95€. Hopefully, this solves the problem!

I had similar symptoms on my 2018 Opel Insignia. It was a control unit communication error. Did you try to read out the error codes? It could be a defective cable or plug connection.
