Hi all,

I live in the UK and my battery requires replacement and as my S5 is already getting older, I can't be bothered to pay Audi for a rip off battery price (almost 500 quid apparently) and additional service/fitment costs. So instead I want to buy an aftermarket battery compatible with the OEM one (e.g. Bosch or Varta) and have it fitted for me, inclusive of the required Battery Energy Management coding.

I called Halfords to check if their fitment includes coding but the 2 different folks I was talking about didn't know what I was talking about and the 3rd guy said "No you have to go to the Audi dealer for that".

So anyone has had their battery replaced and fitted by a firm that sells batteries online for a decent price that also will take care of the coding?

Thanks in advance for all suggestions / tips,

M

Any local VAG specialist mechanic will be able to do this for you.

If it's a like-for-like replacement (i.e. the same size and type of battery) then the coding is very basic - just randomly change one digit of the existing serial number. Any DIYer with VCDS can do that.

if you replace the battery without recoding, the battery management will sort itself out, within a week, may be even sooner.
more important is, that you keep the car under power, when you actually replace the battery.

The battery MUST be coded to ensure proper charging. Without coding the system does not register that it is a new battery. The charging management is different and may affect the life of the battery. The "coding" does not need to actually match the battery. The number in the system just needs to be changed.
