Exhaust Peugeot 407

Common exhaust problems on Peugeot 407, especially diesel HDi models with DPF, relate mainly to diagnostics and maintenance. Typical issues include:

• Failure of exhaust backpressure sensors causing incorrect data to the ECU, resulting in jerks or limp mode.
• Electrical wiring problems simulating sensor failures.
• Obstruction and clogging of the Diesel Particulate Filter (DPF) and catalytic converter from irregular maintenance, leading to power loss and gas backpressure.
• Excessive noise due to leaks or degradation without warning lights, causing vibrations and loud exhaust sounds.

Regular maintenance is essential to avoid total clogging and costly repairs.

Exhaust sensors, such as the pressure sensor before the DPF or the lambda sensor near the catalytic converter, provide critical data to the engine control unit (ECU). This data helps regulate engine performance and emission controls. Faulty sensors or damaged exhaust wiring can mislead the ECU, triggering fault codes, performance degradation, or limp mode.

Replacing defective sensors or repairing wiring harnesses is recommended for proper exhaust system function.

DPF clogging is a frequent issue in Peugeot 407 HDi models. It happens when soot particles accumulate inside the filter due to irregular or insufficient maintenance, or predominantly short engine runs that prevent full regeneration. Consequences include:

• Reduced engine power.
• Increased exhaust backpressure.
• Potential engine damage if the problem is ignored.

Proper servicing and periodic regeneration cycles are required to maintain DPF efficiency and longevity.

Exhaust leaks or damage on Peugeot 407 may cause:

• Loud roaring or rumbling noises during operation.
• Vibrations felt in the cabin or under the vehicle.
• Unusual exhaust smells inside or outside the car.
• The absence of specific dashboard warning lights despite noticeable issues.

Visual and auditory inspections by professionals are important to identify and fix these problems promptly.
