Exhaust Peugeot 407

Common issues reported include faulty exhaust backpressure sensors, electrical harness problems related to exhaust gases, and blockages in the Diesel Particulate Filter (DPF) leading to restricted gas flow and power loss. Unusual noises and vibrations from the exhaust system are also noted without always triggering dashboard warnings.

A failing exhaust backpressure sensor sends incorrect data to the vehicle's ECU, which can cause misfires, power losses, or put the engine in limp mode to prevent damage. Replacing the sensor or temporarily bypassing the sensor harness may resolve these symptoms.

Blockages typically occur due to irregular maintenance leading to rapid clogging of the Diesel Particulate Filter. This causes exhaust gases to back up, reducing engine power and increasing emissions.

• Inconsistent or infrequent regeneration cycles of the DPF
• Low-speed driving that prevents proper DPF burn-off
• Failure to replace or maintain components per manufacturer guidelines

Regular maintenance and prompt servicing are essential to avoid total blockage and costly repairs.

Noisy exhausts can show as excessive rumbling, rattling, or vibrating sounds, especially on HDi FAP engines. Often, these symptoms occur without any warning lights on the dashboard, making diagnostic inspection and acoustic checks necessary.

• Excessive exhaust noise during acceleration
• Unusual vibrations felt through the vehicle
• Potential leaks or holes in the exhaust piping or muffler

Professional inspection is recommended for accurate diagnosis and repair.
