Battery Interrupt Igniter -N253-, REMOVING AND INSTALLING, 12 VOLT: Installing

WARNING: This page is about a different car, the 2022 Audi SQ7 and 2022 Audi Q7. However, it is still accessible from the selected car via links, so may be relevant.

Install in reverse order of removal and note the following:

Make sure the connectors are pushed in all the way and that they engage audibly.

-- Check and erase the airbag control module DTC memory because faults can be stored from when the connectors are disconnected. Use the Vehicle Diagnostic Tester.
