DPF Pressure Sensor for BMW 520d 530d 535d 730d E60 F07 F10 F01 13627789219

The DPF differential pressure sensor measures the pressure difference across the diesel particulate filter to determine how blocked it is with soot. The exhaust gas temperature (EGT) sensor measures the actual temperature of exhaust gases at a specific point in the exhaust system. Both sensors are used by the ECU to manage DPF regeneration - the pressure sensor triggers regeneration when the filter is blocked, and the temperature sensor monitors whether regeneration temperatures have been reached.

Both sensor types can cause similar symptoms when they fail. Common signs include a DPF warning light on the dashboard, the engine entering limp mode with restricted power, failed or incomplete DPF regeneration cycles, increased fuel consumption from excessive regeneration attempts, loss of power under acceleration, and a Check Engine light with DPF or exhaust temperature fault codes. In some cases the vehicle may be locked out of further DPF regeneration until the fault is resolved.

Yes - indirectly. If the DPF pressure sensor fails and prevents the ECU from triggering regeneration correctly, soot accumulation will continue unmanaged. Over time an unmanaged DPF will become completely blocked, requiring forced regeneration by a workshop or DPF replacement. Similarly a faulty EGT sensor that prevents the ECU from confirming regeneration temperatures can cause repeated incomplete regeneration attempts that accelerate DPF loading.

Short distances only. A DPF sensor fault will typically trigger limp mode on modern diesel vehicles, restricting power significantly. Even if limp mode is not triggered, driving with an unmanaged DPF blockage risks complete filter failure. EGT sensor faults can also prevent the turbocharger from receiving correct protection data, risking turbo damage under sustained high load. Both faults should be addressed promptly.

Most modern diesel vehicles with a DPF have two or more EGT sensors - typically one upstream of the DPF and one downstream. Some vehicles also have additional sensors before and after the turbocharger and catalytic converter. Each sensor monitors a different temperature zone and feeds separate data to the ECU. A fault code will specify which sensor position has failed. Use the Vehicle Part Finder to confirm the correct sensor for your specific mounting position.

No programming is required. Both are direct plug-in replacement sensors. Clear stored fault codes with an OBD2 scanner after replacement. If DPF regeneration was previously prevented by the sensor fault, you may need to initiate a forced regeneration using a scan tool to clear accumulated soot before returning the vehicle to normal service.
