Battery Interrupt Igniter, Removing And Installing: Notes

WARNING: This page is about a different car, the 2024 Audi S6 and 2024 Audi A6 Quattro. However, it is still accessible from the selected car via links, so may be relevant.

If, after a collision, a fault in the airbag system is shown in the instrument cluster, check if the crash data is saved using the => Vehicle Diagnostic Tester . If this is the case, check if the fault "Resistance too high" is stored in the DTC memory for the Battery Interrupt Igniter -N253-. If this is the case, the Battery Interrupt Igniter -N253- must be replaced.
The Battery Interrupt Igniter -N253- interrupts the electrical circuit each time an airbag is deployed. The Battery Interrupt Igniter -N253- must be replaced after a deployment.
