Audi engine knock sensor OEM part 077905377G is a used genuine sensor from a donor vehicle, also known as the detonation sensor. This part replaces prior numbers 077905377E and 079905376B. When the knock sensor fails, it can cause engine pinging, reduced performance, or a check engine light, as it monitors combustion vibrations to prevent detonation in 4.2L V8 engines—including both diesel and gas variants found in Audi and Volkswagen applications.
