I pulled the UIF for my car (2007 e92 328i 6sp, prod 10/2006). It reads 7602220. Confirmed by other id's pulled with inpa. This should then be 12 14 7602220 for the full bmw part no. Well, that pulls as a 5- or 6-series or x5 (realoem). wtf ?

is this just a mistake in realoem ? if not, is it even possible ? I guess why not, the engines were the same but still...

the latest DME number at least matches that showing up for my VIN (12148613000) so that is some relief. I also ran winKFP the other day at it does pick up the correct ZB no. and suggests an upgrade...

7602220 is the last program version used on the 328i. Newer MSV80 cars use 8613000, but there aren't any 328i calibrations built for that program variant as far as I can tell.

Even when you upgrade to ZB# 8608330, it will still use 7602220 as the program variant, and that's the part number the DME will show up as. Perfectly normal.

So what you are saying is that realoem is incorrect to list the 12 14 7602220 as only for 5- or 6-series or x5. It should show up as 3-series as well ?

7602220 is a part no. not a program anything, not sure that we are talking same thing here...

I know programming it to later ZB no. will not change the part number. (and BTW I get 8608332 suggested, not 8608330. currently have 7603378)

[Terraphantm]

It is part number that refers to the software installed on the DME. 8608330 (or 8608332 - they're both valid 328 files) refers to the calibration or "maps".

8619542,7598080,8613000,A,8619543DA,0FFFFFFFFFD,000,1 S

Notice how 8608332 uses HW-NR 7602220 and 8619452 uses 8613000

If the 328 had a software variant available for 8613000, then the DME would be flashed with the 8613000 software and that's what the software number would be reported as. But it doesn't, and 7602220 is the what you'll get.

[DaanBMW]

Sorry, the fact that 7602220 is MSV80 is clear, that it shows up in realoem only as a part no for 5/6/x5 and not for 3-series that is what I'm not clear as to why.

[Terraphantm]

Who knows. Probably the 5/6/X5 databases didn't get updated. The part number you order just refers to the software that comes preloaded on the DME. When the DME is reflashed during installation, it gets overwritten, and INPA will reflect whatever was flashed to it.

Can anyone confirm this ? My understanding is that the "Part No." is the part no (as in physical part), not a software no. The software number does get revised upon flashing, but not the part no.

...confused...

I knew I read this somewhere, see FAQ 5 here: http://www.e90post.com/forums/showthread.php?t=1196830

So the 12 14 7602220 should be the actual part not anything that changes. Yet that part no. shows for other bmw models not 3 series, and mfg date From:09/01/2009, whereas my car is 10/2006. Go figure ! Maybe DME was replaced before I got it (in 2011) ?

[Terraphantm]

Both the software and hardware numbers get updated. I've reflashed BMW DMEs hundreds of times. Obviously the sticker on the case itself doesn't change, but what the DME reports does change.

In fact, since you have a 2007 328, I guarantee that the part number on the sticker of your DME will be different from even 7602220.

trust me Terraphantm knows very well what he is talking about
and of course he is correct

[DaanBMW]

well... I gotta say if this is true and it seems it is... I for sure learned something today. A first for sure as (at least for me) the possibility of a part no. (or hardware no.) to change via a software intervention is... novel
