Even afer reading the "outrageous battery" thread (and many more) I see that the battery VO code has been listed in the format of:

"B B090" as in this post:

"$B090" as in this post:

"+B090" as in this post

and "-B090" from your post here

Sorry, but that was confusing for me, and may explain why there so many battery threads- there is no one thread that explains it simply enough for a shadetree mechanic like myself.

I used "-B070" for my 70ah wet cell when I coded my car (which had an existing code of "A090") but please Surly, don't tell me if I did it correctly I will continue to , and find my own answer.
Sorry, Cadman, I was not trying to be a douche by my comment. I had limited time and everything you needed was posted in another post authoured by me. I didn't have time to link you to it but I was hoping you'd find it if you knew it was out there.

I feel your pain on the variation in information you find online which should be very specific.

I'm nowhere near my car or coding stuff, but the "-B070" is what I recall you would need. The "-Axxx" codes are AGM, the "-Bxxx" codes are flooded wet cell.

You need to remove all battery options but the correct one and push the VO/FA to CAS and (N)FRM IIRC. Then you need to change the CAS coding to the proper string (KLASSE_BATTERIE to "70ah") like you already have. Then you'll need to re-register the battery. I used INPA but it looks like there's about a half dozen ways to trigger a re-register.

Then if you use INPA and go into the IBS screens and display the second bank of info (it's F2 in my INPA) you should see the odometer reading for the "first battery change" matching (or close to) your current odo reading. You should also see the charging plan as 70.0 (changed from the 91.0 you would have had before).

Unfortunately my INPA is almost all German right now (something I'm working towards improving) so I don't know any of the exact wording you'd be looking for. My F-key shortcuts could also be different than yours.
