Control unit internal error VW Passat B8?

Hello there,

Today I went to the MOT and didn't pass. They found this error (PICTURE)! I then read all the control units at home with OBD Eleven. The device didn't find any of these errors!

Can anyone give me some advice, other than saying that I don't have to take the car to a VW garage because it's really expensive to have a new control unit installed?

Thanks in advance.

Who says you need to trade ECUs? The impermissible wheel size alone can already explain all three errors.

But in doubt, you can also drive to VW and only read the error codes without having to repair anything.

Then let VW read and see what’s really going on.

Without the exact error code, all searches don’t bring you anything. Before you exchange the control unit, there are countless other points in the repair guide that you control beforehand.
