Zitat von BBMatic;121922...
ps: There is also "ECU: GS 8.55, Engine: M62, Transmission: 5HP24, from 01.05.97 till31.08.97", but again this doesn't appear to cover my Dec 97 car..?
According to the official BMW ETK the GS8.55 is the last version, from 9/1996 till manufacturing stop in 1999.

Even if this would not be the case and your EGS had a newer version (very theoretical...), I don't believe the OBD error codes would change their meaning...
