Code my battry?
 

New battery been in for a while, haven't coded it (VAGCOM) because it seems you need to be a cipher expert to do it. I think it's running a bit on the low side... anyone have a non-mysterious way to code it??? It's got the code markings on it. Thanks

D2 doesn't need the battery coding (no BCM in which to enter the info) so probably just needs a proper charge from an external charger. New batteries are often supplied half charged.

Either that or there's another potential cause for any symptoms e.g. poor connection or charging fault

Oh, well thanks for that information. Yeah I've been doing allot of work with the doors open etc.
