- registered new battery via ista
- also registered via tool32
- when i check on ista as well as inpa, it says 86 AH (it was previously written 90) even though it's coded in NCSExpert CAS as 60
any ideas?
thanks 
**update
Changed VO in CAS and NFRM
Was only able to change to A070 (70ah)
Tried 55 and 60 didnt work
Then i recoded the CAS. Tried 55, 60 and 70
Then registered it after each time
When then checking battery info in inpa and ista, when i code CAS to 55 or 60, it reads 86. When I code to 70, it reads 70.
Seems to me you can't code a lower AGM value.
Anyone have anything to add or suggest that is different so the car sees the proper 60 ah value?
Thanks again |

You might be able to get away with 55ah.
