Mercedes Sprinter DPF Differential Pressure Sensor – Bosch OEM | OM642 3.0L | #6429050100 (2010–2018)

DESCRIPTION:

The DPF differential pressure sensor is one of those parts that gets ignored until it triggers a check engine light or causes a failed emissions test. When this sensor fails or reads incorrectly, your Sprinter's ECU loses the ability to monitor soot loading in the diesel particulate filter — leading to missed regeneration cycles, DPF clogging, and potentially expensive exhaust system damage. This is the genuine Bosch OEM replacement that restores accurate DPF pressure monitoring and keeps your emissions system functioning as designed.

What This Part Does

The differential pressure sensor monitors the pressure difference across the diesel particulate filter (DPF), giving the ECU real-time data on how much soot has accumulated. When soot loading reaches a threshold, the ECU initiates an active regeneration cycle to burn off the buildup and restore filter flow. Without accurate pressure data, the ECU can't trigger regeneration at the right time — leading to progressive DPF clogging, increased exhaust backpressure, reduced power, and eventually a blocked filter that requires costly replacement or cleaning.

Common Symptoms of a Failing DPF Pressure Sensor

• Check engine light with DPF or exhaust pressure fault codes
• Reduced power or limp mode activation
• Incomplete or absent DPF regeneration cycles
• Increased fuel consumption
• DPF warning light on the instrument cluster

When to Replace It

Replace when fault codes indicate DPF pressure sensor failure, after any DPF cleaning or replacement service, or when regeneration cycles become irregular or stop occurring entirely. Always verify the sensor before condemning the DPF itself — a failed sensor can mimic a blocked filter.
