I just swapped nozzles on my 1999.5 TDI. This is the first performance mod I have done on the car in the 6 years I have owned it - bone stock. Just went with the small increase to the .205 Bosch nozzles. Got everything in and fired the car up. Idled really bad, so I logged into my vag-com 303.1 using the 12233 code. I then went to adaption like the how to says to do, and dropped the value and the car started idling perfect with the injection qty at 2.2 mg/R. I then saved the value, exited out and took the car for a spin. Everything was great. Later I started the car back up and it was idling like crap again. Logged back in and checked the idle injection quantity and it was back to the factory amount... For some reason, when I shut the car off and start it back up, the value keeps going back to the factory setting. Anyone have any ideas on how to fix this?
