Thank you for pointing out where the old/original coding was. I reused it and all errors are gone!!! You rock!You wrote

It seems to me your coding for [09] is changed.
Please look at the CodingLog.txt found in your C:\Ross-Tech\VCDS\Debug folder and look for the "1K0 937 086 P" number, where you changed coding. If you aren't sure about something in the log file please paste the contents from that log into a new reply and wrap it in Code (explanation showed here)
