Think it’s to do with making sure the ‘smart’ alternator etc work correctly together with new battery.

Can be done using Carista if you have that.
Just done mine with VCDS, went to 80ah AGM from 70ah EFB+. Coded it ok (AGM = "fleece" for battery construction), but then spent the last 24hrs having to monitor and adjust my Victron DC/DC charger due to the change in Smart Alternator output. TBF, I am being lazy and can't be bothered to run a wire to the charger and using Engine Shutdown DetectionGuessing you know about ‘coding in’ the new battery?
I don’t know how, but know it’s a ‘thing’.
Seems ok now though
Update on battery change.
So after reading in here the post by @ greybeard about the new battery having to be recoded and doing a google search,Thank you Greybeard. I had to ring the near to me from work tyre and battery place with details of van. I asked them about recoding and they said not needed and they don’t do it, and don’t have the decoder etc and I should maybe take it to VW. I said the T6 forum and google says it should be done. I also rang the guy that used to look after our car and motorhome who is really a trusted garage and friend. He got his top bloke to ring me back and said the same it needs to be done and explained why.
As it’s my daily I need it right and was stuck at work until 5pm so decided when I left work to go via Halfords and ask. The guy was really helpful and very knowledgeable in all things battery’s and vw. So I got it done there and then. £147 fitted and coded with five year guarantee.

Not a bad price
There was 10% off both fitting and battery for on demand service which means ruck up and get it done on the day.
