BlueTec Sprinter DPF Differential Pressure Sensor – 3.0 L/2.1 L Vans

SKU: 6429050200 - qty 1

Keep your BlueTec Sprinter’s emissions and exhaust after-treatment system working correctly with this genuine 6429050200 Differential Pressure Sensor — a critical component for maintaining diesel particulate filter (DPF) function and overall engine health:

• Essential for DPF maintenance and exhaust health: This sensor measures the pressure difference (front vs. back) across the Diesel Particulate Filter (DPF), allowing the engine control unit (ECU) to monitor soot accumulation and trigger regeneration cycles when needed. 

• Prevents costly DPF failure and engine damage: A malfunctioning or clogged pressure sensor may prevent proper regeneration — leading to filter clogging, increased exhaust back-pressure, soot mixing with oil, decreased fuel efficiency, and possibly engine damage over time. 

• Direct OEM-spec replacement: The 6429050200 sensor (often listed with OEM/MPN A 642 905 02 00 or supplier code 0281006213) is a genuine replacement part compatible with many Mercedes-Benz / BlueTec Sprinter models. 

• Ideal for diesel Sprinter vans (cargo, transport, high-mileage use): If your Sprinter is used heavily — for delivery, cargo, long distance, or frequent stop-start driving — a healthy DPF system (and thus a functioning pressure sensor) is especially important for emissions compliance and engine longevity.

• Maintenance tip: Replace the sensor if you observe exhaust-system error codes (often related to DPF pressure), frequent regeneration warnings, black smoke, or reduced engine performance. A working sensor ensures that exhaust soot is properly monitored and cleared before it causes damage.

Typical issues this part solves:

• Prevents DPF clogging due to missed/failed regeneration

• Avoids decreased fuel economy, black-smoke exhaust, “limp” mode, or engine warning lights

• Maintains diesel emissions compliance and protects engine from soot/oil contamination

Fitment note: Always confirm the Sprinter’s VIN, engine type, and emissions system before ordering — this sensor is designed for vehicles using a DPF-based exhaust system (common on BlueTec diesel Sprinters).
