So, 1 cant just drop a battery in? Needs VCDS / OBD coding?
Just drop it in and recalibrate windows comfort closing (below).


The battery management in T6 is an old-fashioned one, so it doesn't have any history data. It's true that even this one keeps track how much charge is going in and out - on a short term view. Good news is that it adapts the "ageing" parameters (internal resistance and it's derivatives) based on what it actually sees.

The coding indeed immediately resets "ageing" parameters to ones of new battery. However, the self adapting gradually will correct itself to the same what they would have been immediately by the coding. Certainly the adaptation won't happen overnight but it will catch up in a few weeks.
 
Paid £170 for stop start battery last summer, straight swap, no issues what so ever T5.1
