error code P1612 on my Audi TT AWP
 

Hi,
Could somebody tell me how can i fix the error code P1612 on my Audi TT AWP engine?

I am using the Vag-Com 409.1 software with a USB cable. The report is:
"
18020 - Engine Control Module Incorrectly Coded
P1612 - 35-10 - - - Intermittent
"
I am having problems with my instrument cluster also. It is showing 99999999 in the mileage display and the gas gauge is not working. Are these problems the same reported by the code shown by the Vag-Com software?

Help me please!!!

Thank you for any help.
