It's not the year, it's the fact that it's a V6; those don't use the "universal" 12233 login that the 4-cylinder engines do. The V6s have plethora of different ones.hi looking to adjust my egr settings on my 2004 2.5 tdi v6 (uk model) as the 12233 code doesnt seem to work on this year any idea what it is for this year
I would start by posting an Auto-Scan so people can see exactly what ECU you have, what software it has in it and how it's coded. On those V6s, all of that is important. It's possible someone can then give you a login code that will work (or at least a short list to try) but there are no guarantees.deep joys any idea of how best to find which code is required or is it just try from a list and score off as i go
