Mine is in at the local dealers & here's the response I got when I asked them to check out updating to the latest ECU & SMG software:
"There is no software update for your car or gearbox. I've been told E46s don't run software."

Replied to you via PM but here's the run down.
There's basically two software version for the CSL - the 0301 version which came on all the cars and the update in early 2008?? with the 0401 version.
There are then sub-variants of each which breaks down roughly as follows:
- National Japan version (for their fuel) - option code L807A
- EOBD version
- Data record without EOBD version - option code S861A
- V-max unlimited versions - option code S231A
Each one carries with it its own ZB (part) number which is matched to the hardware variant for the DME.
Here's a screenshot of all the CSL ZB versions on BMW's WINKFP
And here's the screenshot of the BMW parts number system showing which is which (well .. 3 of them at least) - the main ones
Basically here's what's what - ZB numbers (bracket is software number):
Japan version
- 7837338 (7837339) - v-max unregulated
- 7837336 (7837337) - standard Jap version software
EOBD Variants
- 7837328 (7837329) - standard EOBD version
- 7837330 (7837331) - EOBD v-max unregulated
Data Record without EOBD variants
- 7837332 (7837333) - standard non EOBD version
- 7837334 (7837335) - v-max unregulated
Each of those above are for software 0401.
I haven't bothered looking into 0301 version, but can most definitely do if requested.
