Need some help from the experts

Hey guys.
so i brought my Car in last week for a defective windshield wiper motor which was replaced under warranty. they also said there was another error code that i have seen in the past with Vagcom.
lonf story short my wife picked up my car so i was not able to get a explanation of what they did to fix this. this is what was on my printout from the dealer

sorry for the caps i had a scan of the document and copy pasted it. i was going to post a pic on AZ but then i realized it would be followed by 13 pages of TD1 questions haha. but in case yes it was all covered under warrenty and i did not revert anything to stock.
thank you!
