Battery -A-, REMOVING AND INSTALLING, IN LUGGAGE COMPARTMENT (0K0): Installing

Batteries from the Audi Parts Program have a base strip adapter for conforming to different clamping strips. See the battery operating instructions for information on when and how to use the base strip adapter.

At vehicles using a central venting system hose, this hose needs to be inserted in the respective vent opening at the battery again. The vent opening on the opposing side must be cosed with a blind plug.

-- Push the battery all the way on the retaining bracket -1- -arrow- so that it contacts the battery clamping strip.
