Hi all. Please can someone give me a definitive answer to what Battery I need for my A6 (C6) 2.4 Quattro Avant 2007. It is a 110 Type

Also do I need to recode the car to accept this. Do I need a battery with BEM code.

There seem to be many views on this hence coming here !

Cheers

Hello Richard, 

It’s usual to simply take all the details (Ah, cold cranking current etc) and dimensions off the existing battery and replace with the same specification and physical size. However, the downside of that is a previous owner may have fitted a non standard replacement. 

Having recorded all the detail, have you talked with the specialist on line suppliers such as Tanya, Battery Megastore etc. and taken their advice? Reg. no will also be required. Could be an AGM type battery, but possibly too early for that. I now only buy premium batteries by Varta or Bosch, selecting their grades which have at least a 4 year warranty. 

Perhaps you could let us know who you have enquired with to date. 

Kind regards,

Gareth. 

Hi, Many thanks for reply

The battery fitted is not the original nor OEM.

Have tried Tayna, GSF and some others who give long lists of options.

My biggest query is do I need to recode the car to my new battery. If so I need a BEM code which doesnt come with all batteries. Lots of forums talk about it and some say dont bother ?

Cheers

Hello Richard,

I would have thought your first concern would be to establish which of the options is the correct one for your car. Hopefully someone on here will advise what battery fits their same-model-as- your car. 

Code for battery? I wouldn’t have thought so on a 13 year old car. 

Kind regards,

Gareth. 

My rough knowledge, I believe if the battery is the identical spec it won't need coding.
