A Diesel Particulate Filter (DPF) traps the harmful soot produced by the engine, which must be burned off regularly through a process called regeneration. Blockages occur if the car is only used for very short journeys, which prevents the engine from reaching the necessary high temperatures. A blocked DPF severely restricts exhaust gas flow, causing a drop in engine power and increased pressure that can actually damage the turbocharger. The DPF warning light will usually be the first sign that there is a critical problem.

Affected Models:

Peugeot 208, Peugeot 308, Peugeot 3008 (All diesel engine models)

Symptoms:

The orange DPF warning light or the engine management light will illuminate on the dashboard.
A noticeable loss of engine power, or the car enters a restricted limp home safety mode.
Increased fuel consumption as the engine works harder to overcome the restriction.
Black or dark smoke coming from the exhaust pipe, especially under acceleration.

Common Causes:

Frequent short journeys prevent the engine from reaching the temperature needed for regeneration.
Failure of a component like the glow plug or the exhaust gas recirculation (EGR) valve.
Using an incorrect type of engine oil (non-low-SAPS oil) can cause excessive soot buildup.
Faulty sensors within the DPF system can interrupt the important regeneration process.

Solutions:

Drive the vehicle at highway speeds for 30–45 minutes to initiate passive regeneration.
A professional garage can perform a forced regeneration using specialized diagnostic equipment.
For more severe blockages, the DPF must be removed for ultrasonic or chemical cleaning.
If the filter is physically damaged beyond repair, a full replacement of the DPF unit is necessary.

Estimated Repair Cost:

13. Suspension Noise

What Happens:

Suspension noise is any abnormal sound coming from the wheel arches, such as a squeak, clunk, or rattle, especially when driving over bumps. These noises are not usually a problem with the main structure; they signify that a smaller, crucial component has either failed or become severely worn. Ignoring the noise is dangerous because it indicates excessive movement, which places stress on other parts. The specific sound often helps a technician accurately diagnose the actual source.

Affected Models:

Peugeot 208, Peugeot 2008, Peugeot 3008 (Common in most models due to worn bushings)

Symptoms:

A loud clunking or knocking sound occurs when you drive over potholes, bumps, or uneven surfaces.
A constant, irritating creaking or squeaking noise is heard when you turn the steering wheel or get into your vehicle.
A rattling sound is audible when driving on rough roads, suggesting a loose component like a sway bar link.
The steering feels loose, or you notice the car slightly drifting when you are driving straight.

Common Causes:

Failed rubber bushings on the control arms or anti-roll bar, which allow metal parts to rub together.
Worn or dried-out ball joints and tie rod ends, leading to excessive play and a distinct creaking sound.
Failure of the strut top mount bearings, which causes a knocking or thudding noise when you turn the wheel.
Loose or damaged sway bar links that rattle against the suspension components under stress.

Solutions:

A mechanic will inspect all rubber components; replacing the worn-out bushings and ball joints is the most common fix.
You can sometimes use a silicone-based lubricant to quiet a squeak from a dried-out bushing temporarily.
If the strut top mount has failed, you must replace the entire assembly to eliminate the rotational noise.
A proper diagnosis is essential because noises in the suspension often get complicated very quickly.

Estimated Repair Cost:

Anti-Roll Bar Link/Bushings Replacement: ~AED 550–1,600.
Control Arm Bushing/Ball Joint Replacement: ~AED 900–2,200 (Per side).

14. Power Steering Problems

What Happens:

Power steering problems in Peugeots, especially models with Electric Power Steering (EPS), can result in a sudden or intermittent complete loss of steering assist.

Braking System Concerns

15. Brake wear (Brake discs)

What Happens:

Brake wear is a common, expected maintenance issue that refers to the deterioration of the braking components, particularly the discs and pads. The brake system works by using friction to slow your car, which means the brake pads naturally wear down over time and the discs will develop scoring, warping, or an uneven surface. Allowing the discs to become too thin or damaged significantly reduces your car's stopping power, creating a dangerous driving situation.

Affected Models:

Peugeot 308, Peugeot 508, Peugeot 2008

Symptoms:

You hear a noticeable, high-pitched squealing noise when you apply the brakes, indicating the pads are critically low.
A severe, loud grinding sound is audible when you brake, suggesting metal-on-metal contact due to completely worn pads.
You feel a distinct vibration or pulsation through the brake pedal when you slow down, which is a sign of warped brake discs.
The brake pedal feels softer, or you notice that your car requires a longer distance to stop completely.

Common Causes:

Normal operational wear as the brake pads and discs are designed to be friction components that eventually wear out.
Hard braking, aggressive driving, or frequently driving in stop-and-go traffic will accelerate the rate of wear.
Poor quality or incorrect installation of replacement brake pads can quickly damage the surface of the disc.
Exposure to excessive heat, like sustained downhill driving, can cause your brake discs to warp unevenly.

Solutions:

You must regularly inspect your brake pads and discs and replace them when they reach the minimum safe thickness.
A mechanic will measure the disc thickness and surface condition to determine if they need replacement or just light skimming.
Always replace the brake pads and discs as a complete set on the same axle to maintain equal braking performance.
Choose high-quality, reputable pads and discs during a replacement to ensure optimal performance and longevity.

Estimated Repair Cost:

Brake Disc and Pad Replacement (Per Axle): ~AED 1,200–2,500 (Cost depends on the disc type and model).

Cooling & Temperature Control

Proper maintenance and timely repair are crucial for comfort and system health.

Affected Models:

Peugeot 207, Peugeot 307, Peugeot 308, Peugeot 407

Symptoms:

The air blowing from your vents is only warm or humid, or the cooling is dramatically less effective than usual.
You hear loud, unusual clicking or grinding noises when the AC system attempts to engage the compressor clutch.
You notice weak air flow from the vents, even when the fan setting is turned up to a high level.
The system cools better while you are driving at speed, but starts to blow warm air when the car is idling.

Common Causes:

A refrigerant leak in the system, often from worn O-rings, damaged hoses, or a punctured condenser.
Failure of the AC compressor, which is the system's pump and frequently results from low oil or extreme wear.
A faulty electric cooling fan or condenser fan motor, which prevents the refrigerant from cooling properly at low speeds.
Clogging of the cabin air filter, or an electrical issue with a fuse, relay, or climate control sensor.

Solutions:

A certified technician will first perform a system pressure test and use an ultraviolet dye to locate any refrigerant leaks.
You must seal all leaks and then properly recharge the system with the correct type and amount of refrigerant gas.
If the compressor is failing, it often needs a complete replacement to restore the cooling function.
Routinely changing the cabin air filter is a simple, effective maintenance step for maximizing airflow.

Estimated Repair Cost:

AC System Recharge (without leak repair): ~AED 600–1,200.
Compressor Replacement: ~AED 3,000–5,000 (Cost depends heavily on the specific Peugeot model).

17. Cooling System Leaks

What Happens:

Cooling system leaks are a serious issue; they cause your engine to lose the vital coolant needed for temperature regulation, which can quickly lead to overheating and severe engine damage.
