Battery Replacement

[Battery replacdement]

BMW say it will not work satisfactorily unless installed by them at a large cost.  Can that be right?

Sorry for the very late reply. 
depending on the car model, the later ones need the battery coding to the car so it can monitor levels. I think anything before 2005 is just swap and start the car.

battery coding will be part of the installs process at bmw, so costs will be high. 
 

google bmw battery coding and see if your model needs it, there are various how to guides if you have the correct software.

Morning Geoffrey

As Stu has said later cars need the battery coding, the charging system needs to know whether the battery is AGM or Lead Acid plus what it's capacity is to ensure correct charging. 

Any good garage with Auto Logic software or better still a BMW Specialist (Google BMW Specialists) will be able to do the job for a lot less than a BMW Dealer. If you have or know someone with Inpa or Carly then you can DIY

Good Luck
