Here are the integration levels:
2.46.1 and 2.46.2 are E89-12-03-502.
2.46.0 is E89-12-03-500
2.45.X is E89-11-09-506
2.44.X is E89x-11-09-505
2.43.1 and .2 is E89x-11-09-503
2.43.0 is E89-11-09-501
2.42.X is E89x-11-03-511
I suspect that 231E was introduced around 2.45. I just checked my car and it has 220E.
Have been updating a few cars lately... Those of you that want to flash the DME, I can update it in about 10 or 15 minutes. Can also do it remotely.
Thank you. That was just what I was looking for. I have a 05/11 build. I'm going in for service shortly, I'll inquire.
Very much appreciated.
