How to code new car battery? VCDS.

When you are changing your car battery for exactly the same you had before in most cases you don’t need to recode it however in most cars battery regulation module might be a bit confused about new battery, why?

When you replacing your battery to a new one, it might have different capacity of pawer, in most cars battery regulation module does not measure current battery level but only taking a measure of consumed power and how much power it deliver (charge) to battery.

Also remember, when you are placing a new battery, make sure it’s charged in 100% before you’ll put in a car and start coding.
