Maybe your ECU is expecting some communication with a transmission control module, which as a 5-speed manual, it doesn't have.

You need to get the codes read via VAG-COM . Then do a search for what the codes mean.

Transmission codes are not part of OBDII so you are wrong

Buy/ borrow a VAG.com and recode the ECU for manual transmission.

Most folks doing maintenance on their own cars won't have or need all that factory test equipment to recode the ECU the way AudiMick explained. A diagnostic scan cable, and a computer with licenced VAG-COM does it.

If one is going to work on their own car this is a must and a cheap tool.

If you post in the local forums either here on AW or the other audi forums you will probably find someone local with a VAG-COM
