I called one of the BMW specialty shops recommended by RepairPal for no start. The shop claimed that most likely the battery needs to be replaced. I know from the dealer that you have to program a computer in the car anytime you replace a battery. I told this to the mechanic but he started laughing and said that the dealer probably wants to make extra money. So, I don't know now if you have to or don't have to program the computer. Please answer asap!

I believe the battery has a box on top of cover and if it does then yes it will need to be programmed.

Some really new BMWs do need a reprogram after a battery replacement, they are so overly sophisticated the article I read said the computer wants to know if the battery was replaced so it can modify the characteristics of the charging system. Why do the complicate what should be a simple system.

Can I replace the battery without a visit to the dealer? What is the proper size battery?
