Hello, I found this error on my Skoda Superb 2018. If I erase memory, immediately this error is back. Can someone help me please?

Is that coding right?   Have you changed anything within central electrics (09) recently?  

You're probably best getting this moved over to the VCDS and Diagnostics board.

I fixed this problem after few months, it was due wrong activation of maneuvering lights
