1. Dual Mass Flywheel (DMF) Failure

Peugeot Expert Volksmaster Van Centre

A common weak point, particularly in models that have regularly carried heavy loads or tackled a lot of stop-start city driving.

• Symptoms:
  • Loud, aggressive clunking or knocking noise when idling or switching off the engine.
  • Excessive vibration through the clutch pedal, gear stick or floorpan.
  • Clutch judder or shuddering, especially when pulling away in first gear.
• Causes:
  • Wear and tear of the internal springs and damping mechanism due to high torque or heavy strain.
  • Premature failure exacerbated by excessive heat or oil contamination from a seal leak.
• Fixes:
  • Replace the Dual Mass Flywheel, often alongside a full clutch kit (part number varies – confirm with VIN).
  • Replace the rear main oil seal if any oil contamination is detected.
  • Quick Tip: When pulling away, release the clutch smoothly and avoid riding it unnecessarily to reduce stress on the DMF.

2. Exhaust Gas Recirculation (EGR) Valve Blockage

A regular culprit in modern diesel vans, especially those used for short journeys that prevent the engine from reaching optimum temperature.

• Symptoms:
  • Illumination of the Engine Management Light (EML).
  • Noticeable loss of power and reduced acceleration.
  • Stuttering or lumpy idle, sometimes leading to the engine stalling.
• Causes:
  • Carbon and soot deposits building up in the EGR valve, causing it to stick open or closed.
  • A faulty EGR solenoid or electronic control element.
• Fixes:
  • Clean the EGR valve using a specialised chemical cleaner or ultrasonic cleaning.
  • Replace the entire EGR valve assembly (part number varies – confirm with VIN).
  • Quick Tip: Once a week, take the van for a 30-minute run on a motorway or fast A-road to get the engine hot and help burn off deposits.

3. Turbocharger Failure (Common in 1.6 HDi)

Peugeot Expert Engine

The 1.6 HDi engine fitted to many Experts can be prone to turbo issues if not diligently maintained.

• Symptoms:
  • Excessive blue or black smoke from the exhaust.
  • A distinct, loud whistling or whining noise under acceleration.
  • Severe loss of engine power, often referred to as ‘limp mode’.
• Causes:
  • Oil starvation or contamination due to poor maintenance schedules, clogged oil feed lines, or a worn oil sump strainer.
  • Internal seal or bearing failure from overheating or excessive wear.
• Fixes:
  • Replace the faulty turbocharger unit (part number varies – confirm with VIN).
  • Critically, ensure all oil feed pipes, the oil sump strainer and the intercooler are cleaned or replaced to prevent immediate failure of the new unit.
  • Quick Tip: Always use the correct, high-quality engine oil and change it strictly according to the service schedule. Allow the engine to idle for a minute before switching off after a long run to cool the turbo.

4. Worn Front Anti-Roll Bar Links/Bushes

The front suspension takes a lot of punishment from carrying tools and navigating Britain’s pothole-riddled urban roads.

• Symptoms:
  • A persistent, loud clunking or knocking noise from the front of the van, particularly when driving over bumps, speed ramps or uneven surfaces.
  • A feeling of looseness or imprecision in the steering.
• Causes:
  • Wear and failure of the rubber bushes or ball joints on the anti-roll bar links (often called ‘drop links’).
  • Constant heavy loading exacerbates the natural wear of the suspension components.
• Fixes:
  • Replace the worn anti-roll bar links/bushes (e.g., replacement link part number Delphi **TC1191** or equivalent, but confirm with VIN as lengths vary).
  • Inspect all associated suspension components (wishbones, shock absorbers) for secondary damage.
  • Quick Tip: Have your van’s suspension visually checked at every service; small repairs like these are far cheaper than replacing major components.

5. Diesel Particulate Filter (DPF) Blockages

Another issue for diesel vehicles, especially for tradespeople whose work involves frequent short journeys.

• Symptoms:
  • DPF warning light illuminated on the dashboard.
  • Engine entering ‘limp home’ mode with severely restricted power.
  • Increased fuel consumption and the cooling fan running constantly.
• Causes:
  • Insufficient regular driving at high speeds/temperatures needed for the DPF to self-regenerate (burn off collected soot).
  • Using the incorrect oil type (low-SAPS oil is essential for DPF-equipped engines).
• Fixes:
  • Perform a forced DPF regeneration using diagnostic equipment.
  • Professionally clean the DPF, or replace the DPF unit if severely blocked (part number varies – confirm with VIN).
  • Quick Tip: If the warning light comes on, drive the van for 15-20 minutes on a motorway above 40 mph to try to trigger an automatic regeneration before consulting a mechanic.

6. Notchy or Difficult Gear Shifting

Peugeot Expert Dashboard

Some models can develop problems with gear engagement, making driving a chore, especially in busy traffic.

• Symptoms:
  • Difficulty selecting gears, particularly first and reverse.
  • A general ‘notchy’ or stiff feeling when moving the gear stick.
  • Excessive play or looseness in the gear lever.
• Causes:
  • Worn or stretched gearbox selector cables or linkages.
  • Low or contaminated manual gearbox oil.
  • Internal gearbox component wear, often related to the clutch release bearing or synchro rings.
• Fixes:
  • Replace worn gear linkage cables and bushes (part number varies – confirm with VIN).
  • Drain and refill the gearbox with fresh, manufacturer-specified transmission fluid.
  • Quick Tip: Avoid resting your hand on the gearstick while driving, as this can place unnecessary wear on the internal mechanism.

7. Electrical System Gremlins

Like many French vehicles, the Expert can occasionally suffer from minor, yet frustrating, electrical faults.

• Symptoms:
  • Central locking system malfunctioning (e.g., doors failing to lock or unlock on the first try).
  • Erratic behaviour from the dashboard instruments, infotainment system or interior lights.
  • A drained battery with no obvious cause.
• Causes:
  • Damp or corrosion in wiring looms or connectors, particularly in door cavities.
  • Faulty door lock actuators or a weak battery/alternator.
• Fixes:
  • Thoroughly inspect and clean/reseal any corroded wiring harnesses.
  • Replace faulty door lock actuators (part number varies – confirm with VIN).
  • Quick Tip: Keep the area around the battery and fuse boxes clean and dry, especially during wet weather.

8. Excessive Front Tyre Wear

Owners often report that front tyres wear out prematurely, costing more in replacements over the van’s lifetime.

• Symptoms:
  • Tyres wearing heavily on the inside or outside edge.
  • Need for frequent replacement of front tyres compared to the rear.
• Causes:
  • Incorrect wheel alignment (tracking) due to hitting potholes.
  • Worn steering or suspension components affecting the vehicle’s geometry under load.
  • Constant heavy loads placing extra strain on the front axle.
• Fixes:
  • Have a full four-wheel laser alignment (tracking) check performed and adjusted, particularly after suspension work.
  • Replace any worn track rod ends or ball joints.
  • Quick Tip: Check tyre pressures weekly—running even slightly under-inflated will dramatically increase shoulder wear.

9. Fuel Pressure/Pump Issues

Peugeot Expert Manchester

A less common but serious issue that can manifest as severe power loss or stalling.

• Symptoms:
  • Engine fault warning light and a sudden, complete loss of power under acceleration (limp mode).
  • Engine sputtering, difficulty starting, or unexpected stalling.
• Causes:
  • Malfunction of the low or high-pressure fuel pump.
  • A clogged fuel filter or contaminated fuel.
  • Faults in the associated wiring loom or pressure sensors.
• Fixes:
  • Diagnostic check of the fuel pressure system to isolate the failing pump or sensor.
  • Replace the faulty fuel pump and always replace the fuel filter (part number varies – confirm with VIN).
  • Quick Tip: Only refuel at reputable filling stations and ensure the fuel filter is changed at the prescribed intervals to protect the pumps.

10. Clutch Wear and Judder

While often related to the DMF, the clutch itself is a major wear component, especially when the van is towing or carrying a maximum payload.

• Symptoms:
  • Engine revs rising disproportionately to road speed (clutch slip).
  • A burning smell (especially after hill starts or reversing).
  • Difficulty getting into gear, even when the pedal is fully depressed.
• Causes:
  • Worn friction plate or pressure plate.
  • Aggressive driving or constant heavy-duty use.
• Fixes:
  • Install a new clutch kit, including the pressure plate, friction plate and release bearing (part number varies – confirm with VIN).
  • Quick Tip: When stationary, place the gearbox in neutral instead of holding the clutch down—this prevents unnecessary wear on the release bearing.

11. Steering System Heavy or Clunky

A noticeable change in steering feel indicates an issue that needs immediate attention for safety.

• Symptoms:
  • Steering feels heavy or requires excessive effort to turn.
  • A clunky noise or feeling when turning the wheel at low speeds.
  • Warning light for power steering on the dash.
• Causes:
  • A seizing universal joint (U-joint) in the steering column, often near the footwell.
  • Failure of the power steering pump or a fluid leak (in hydraulic systems).
• Fixes:
  • Inspect and replace the steering U-joint if seized.
  • Top up or replace power steering fluid, or replace the power steering pump (part number varies – confirm with VIN).
  • Quick Tip: If your steering is hydraulic, check the fluid reservoir for the correct level and look for any weeping pipes monthly.

12. Starter Motor Issues

Peugeot Expert Tameside

Especially noticeable on cold, frosty mornings in the North West.

• Symptoms:
  • Engine fails to turn over, resulting in a single “click” when the key is turned.
  • Slow or laboured cranking of the engine.
  • Requires multiple attempts to start the vehicle.
• Causes:
  • Worn-out starter motor solenoid or carbon brushes.
  • Poor electrical connection to the starter motor or a weak battery.
• Fixes:
  • Test the battery and electrical connections; clean or replace corroded terminals.
  • Replace the faulty starter motor unit (part number varies – confirm with VIN).
  • Quick Tip: Ensure your battery is fully charged and in good condition before winter arrives; a struggling battery puts extra strain on the starter motor.

13. Premature Brake Pad and Disc Wear

Owners report that the brakes can wear quicker than expected, especially when the van is used for heavy-duty work.

• Symptoms:
  • Squealing or grinding noise when braking.
  • Vibration through the brake pedal when slowing down (indicates warped discs).
  • Brake fluid warning light illumination.
• Causes:
  • Consistent heavy loads placing maximum strain on the braking system.
  • Overheating caused by frequent braking in traffic or descending steep hills.
  • Inferior quality brake pads or discs.
• Fixes:
  • Replace worn brake pads and discs with high-quality, OEM-equivalent parts (part number varies – confirm with VIN).
  • Ensure brake calipers are functioning correctly and not sticking.
  • Quick Tip: Whenever possible, use engine braking (shifting down a gear) on long declines to save your service brakes.

14. Engine Management Light (EML) Faults

Volksmaster Peugeot Expert Service

A common electronic warning that requires specialist diagnostic equipment to accurately interpret.

• Symptoms:
  • The orange EML stays illuminated, sometimes flashing.
  • Often accompanied by the van entering ‘limp mode’ with reduced power.
• Causes:
  • Faults can range from a simple loose fuel cap to serious issues like DPF blockages, lambda sensor failure or injector problems.
  • Often, the fault code points to a sensor reading outside of expected parameters.
• Fixes:
  • Have the vehicle scanned immediately using a professional diagnostic tool to retrieve the specific fault code.
  • Follow the diagnostic procedure to replace the faulty component (e.g., a lambda sensor or injector) based on the specific code (part number varies – confirm with VIN).
  • Quick Tip: Never ignore the EML; although it may sometimes be a minor sensor issue, it can quickly lead to costly engine damage if the root cause is ignored.

FAQs: Your Peugeot Expert Questions Answered

We know you have questions about keeping your van in top condition. Here are some of the most common queries we receive about the Peugeot Expert’s maintenance and repair.

1. How often should I service my Peugeot Expert?
   For most modern Expert models, a service is recommended every 12,000 miles or annually, whichever comes first. Heavy-duty use, like regular towing or maximum payload, may warrant more frequent oil changes.
2. Is the Peugeot Expert generally reliable?
   Yes, the Expert is considered a solid, reliable van, highly favoured by trades. Most common issues are wear-and-tear items exacerbated by heavy use or high mileage, such as the DPF and DMF.
3. What oil should I use in my 1.6 HDi Expert?
   It is crucial to use a high-quality, low-SAPS (Sulphated Ash, Phosphorus and Sulphur) engine oil, typically a 5W-30 synthetic, which meets the manufacturer’s specific OEM standard (e.g., PSA B71 2290). This is vital for DPF longevity.
4. What should I check before buying a high-mileage Expert?
   Inspect the clutch and listen for DMF noise (clunking when switching off), check for excessive blue/black smoke (turbo/DPF), and look for receipts confirming cambelt changes and regular servicing.
5. How much does a new clutch/DMF replacement cost?
   Costs vary greatly based on the component’s model year and engine, but expect a full clutch and Dual Mass Flywheel replacement to be one of the most significant repair bills for the Expert.
6. Does the Expert have a cambelt or a timing chain?
   Most Expert models utilise a cambelt (timing belt). The replacement interval is typically between 70,000 and 100,000 miles or every 5 years, but you must check the exact schedule for your engine type (e.g., 1.6 HDi or 2.0 HDi).
