The Audi airbag impact/crash sensor (OEM 4D0959643A) is a used genuine safety component from a donor vehicle. This sensor, also called the crash or impact sensor, mounts on the left or right side and detects collision forces to trigger airbag deployment. It fits Audi A8 and A8 Quattro models with the 3.7L or 4.2L V8 engines. Because it is a safety part, installation must be performed by a qualified technician. A failing sensor may illuminate the airbag warning light or prevent the airbags from deploying in an accident.
