I have a 01 B5 Passat in the shop that required a replacement ECU. The previous ECU flooded and had heavy corrosion on the board which prevented me from communicating with the ECU. I purchased a matching number (only manufactured 1 day apart) used ECU online from a seller in the N.E. United States (Massachusetts). When I checked the soft coding on the used replacement ECU it shows that the previous car was coded as a 16 ULEV (ultra low emission vehicle). The software coding was 16551 being ULEV (16), FWD (5), automatic trans 01V/09A (5), B-class Vehicle type (1). The workshop coding was 01084. A few years ago I lived in Massachusetts and worked mainly on BMWs and recall very few BMW ULEV cars that were unique with added emissions devices. Those cars were only sold in parts of the north east US and California (perhaps other parts of the world as well).
Since I never had a chance to acquire an auto scan from the car before the customer came in and the ECU was bad, how can I tell if this car should be a (16) ULEV or (07) N. American LEV? Were all North American Passats ULEV? The car is running fine as is with used ECU but I'm tempted to change the soft code to 07551. I am currently unable to post the auto-scan as my netbook is not connecting to the internet for some odd reason. I'm working on getting it resolved. Hopefully, someone can answer the question without it.
