But that seemed to have already been concluded in the thread and the talk had switched to a replacement battery. There seems to be issue with what battery you actually have in the car. Along with the question about the PR code (if you have your PR codes sticker on hand) and whatever info is on the top of the battery, what part number is programmed in the adaptation value (CAN Gateway, adaptation channel 04)?
I did find the part number actually: It is the 92aH battery from Varta. Is it really worth it to put an AGM battery in here though as opposed to just getting a regular flood battery?
