Mercedes-Benz engine knock sensor (OEM 2709050900) – a used genuine part from a donor vehicle. This knock sensor monitors combustion for detonation and sends a signal to the ECU to adjust timing. When it fails, you may see a check engine light, reduced power, or excessive engine noise. It covers numerous Mercedes models with inline-4, V6, and V8 engines (including turbocharged and naturally aspirated variants). Genuine OEM ensures proper sensitivity and fit.
