I'm looking to change the battery in my A6 as its the original one and over the winter failed to start the car on a 2 occasions.

I'm looking at replacing it with a Bosch S6 002, which seems identical to the current Audi branded battery which is fitted, same CCA, AH etc.

Does anyone know if i'll need to recode the car to tell it that it has a different battery, given that the CCA, AH etc is the same?

I'd read somewhere that the battery management system could playup if not told of the correct battery?
Thanks
