Hi, first post here. I found the following online:
https://www3.epa.gov/otaq/cert/docum...ied-models.xls
Which shows the 230 models as certified.
My 230 xdrive is currently on the Undine, scheduled to arrive in NJ on 7 Sept.
I hope the above-mentioned "diagnostic hold" will not apply to all incoming 230's (perhaps it really is a diagnostic problem on that specific vehicle).
Good luck!
