Audi VCDS new battery coding instructions

In most circumstances, you don’t need to recode your old battery when you replace it with one that is identical to the one you had before. However, the battery regulating module in most cars could be slightly puzzled by the new battery for unknown reasons.

In most cars, the battery regulating module only measures the amount of power that is consumed and the amount of power that is delivered (charged) to the battery. This means that when you replace your battery with a new one, it may have a different capacity of power.

In my view, you should always recode it when changing batteries.

Also keep in mind that before installing a replacement battery in a car and beginning any coding, make sure it is fully charged.

How do I code an Audi new battery?

You’ll need VCDS, the VAO code from the new battery, and the serial number to do this. Only when you purchase a battery from an Audi service will you receive a VAO code; we have a list of frequent codes you can use in VCDS.

You need to visit the in cars with battery regulating modules for:

[61 – Battery Regulation] in some cars it might be also in [09 – Cent. Elect.] or in Gateway – so if you don’t have Battery regulation try to find them in other modules.

[Coding – 07]

[battery Coding Assistant]

Choose the second choice, which is your battery, from this menu.
