    Battery Coding - Measuring Blocks - A8 (4E)

    Audi A8 - BEMS - Measuring blocks - as in can anyone identify how I can verify that the 'coding' has been properly accepted for a battery change.

    Whenever I try to save I get a 'coding rejected' message, I generate the coding within the tool based on the VAG part number - 000905105DL - 110Ah Battery, I modify the serial by one digit since the battery (a new Varta Silver has no serial number and I fail to see why this would impact the controller anyhow other than telling it the battery has changed)

    If I try to change a second time I get a warning that the 'length' has changed. I have yet to get a success when saving coding on the battery so I want to verify that it has behaved in the measuring blocks - currently it looks like it hasn't and is showing the battery as available capacity 1000 in measuring group 3 which I think is wrong for the part number - and the battery - was expecting to see 1100.

    Can anyone confirm what / where to verify things - if the BEMS has been 'limited' to 100Ah maximum because that's the recommended battery is there an adaptation channel to 'fix' it - I have zero intention of fitting a 100Ah battery that is only pennies cheaper than a 110Ah.

    BEMS coding below - taken before doing battery swap - just noticed part number - going to check that now ... checked - the part number and serial that I entered are saved in the block ...

    So if that data is from before the battery swap (and associated attempts to change coding), how about posting current data so we can compare?
