Peugeot Expert: common problems and points to watch out for

The Peugeot Expert is a popular van chosen by many professionals and families thanks to its versatility and practical load space. This compact van combines French quality with modern technology and is available as both a diesel and an electric version. However, the Expert also has a number of common issues. Owners and potential buyers should take these into account. This article highlights the main points of attention for the Peugeot Expert, so you know what to look out for.

Why the Expert is a good choice for professionals

The Peugeot Expert is a modern, reliable van for business use and family transport. The van offers space for up to 9 passengers in the combi version and up to 6,100 litres of load volume in the pure cargo version. The Moduwork system allows a flexible layout with a folding passenger seat and a through-loading hatch for long items up to 4 metres. Standard features such as the i-Cockpit interior with 10-inch touchscreen, digital instrument panel and hands-free sliding doors make everyday use comfortable.

The Expert is available with economical 2.0-litre diesel engines producing 120 to 150 bhp, or as the fully electric e-Expert with a 75 kWh battery and a range of 314–370 kilometres according to WLTP (Worldwide Harmonised Light Vehicle Test Procedure, the new European test method for consumption and emissions). Still, it is wise to familiarise yourself with possible car problems with Peugeot, because this popular van also has certain weak points that occur regularly.

Engine problems that Expert owners encounter

The diesel engines in the Peugeot Expert are known to be reliable and economical, but some components can start causing issues over time. The EGR valve (Exhaust Gas Recirculation, a valve that recirculates exhaust gases to reduce emissions) is a frequently mentioned point of attention. This valve recirculates exhaust gases to lower emissions but can become clogged with soot deposits. This leads to loss of power, irregular idling and sometimes the engine warning light coming on.

The turbo can also be prone to wear at higher mileages, especially when maintenance is not carried out on time. Signs of turbo problems include whistling noises, smoke from the exhaust or sudden loss of power. Injectors can likewise become contaminated, leading to poor starting, higher fuel consumption or rough engine running. Regular use of quality fuel and timely replacement of air and fuel filters helps prevent these problems.

With the electric e-Expert, motor problems are rare, but software updates may be needed for optimal functioning of power management. Owners report that acceleration above 50 km/h in Eco or Normal mode is limited, which affects driving characteristics.

Transmission and clutch may require attention

The Peugeot Expert is available with a 6- or 8-speed gearbox, both manual and automatic. With manual versions, the clutch can show signs of wear under heavy use and at high mileages. This is especially true when the van is regularly heavily loaded. Symptoms include engine speed rising without acceleration, vibrations when shifting or a slipping clutch when pulling away.

Automatic gearboxes generally cause fewer problems, but jerky gear changes or delayed responses can indicate contaminated transmission oil or software issues. Have the transmission oil replaced according to the maintenance schedule, even if this is not always explicitly listed as a service item. This prevents unnecessary wear and costly repairs.

Main transmission points of attention

• Check the clutch for wear when buying second-hand
• Watch out for jerky shifts with the automatic gearbox
• Have transmission oil replaced on time according to schedule
• Heavy loads accelerate clutch wear

Electrical faults and systems can be tricky

The Peugeot Expert is equipped with modern electronics and safety systems such as Lane Keep Assist, automatic emergency braking and a 360-degree camera. These systems rely on sensors, wiring and the BSI unit (Body Systems Interface, the central module that controls all electrical systems in the vehicle). These components can sometimes suffer faults. Problems with the BSI unit do occur and can lead to failure of electrical functions such as central locking, lighting or the infotainment system.

Sensors for parking assistance, blind spot monitoring and tyre pressure can become dirty or fail, causing error messages on the dashboard. Wiring in the load area or at the rear doors is vulnerable to damage from heavy use, especially with frequent loading and unloading. This can lead to failure of the rear lighting or sensors.

It is sensible to have electrical problems diagnosed quickly with professional equipment. Fault codes are often stored which immediately point to the cause. When buying a second-hand Expert, have all electrical functions thoroughly tested, including sliding doors, lighting and safety systems.

Suspension and steering require periodic checks

The suspension of the Peugeot Expert is solidly built to carry loads, but components wear due to heavy use and poor road surfaces. Shock absorbers can weaken over time, leading to reduced comfort and less stable handling. Signs include sagging when loaded, rattling noises over bumps or uneven tyre wear.

Control arms, bushes and drop links in the front suspension are prone to wear, especially at high mileages. This can cause knocking or banging noises when steering or driving over uneven surfaces. Have these components checked during services and replace them in good time to prevent further damage and unsafe situations.

The steering rack and power steering generally cause few problems, but leaks in the steering system or heavy steering can indicate a fault in the pump or pipework. The brakes show normal wear, with discs and pads needing replacement according to the wear indicators. Check brake fluid regularly and replace it according to the maintenance schedule.

Bodywork and interior: what to look out for

The bodywork of the Peugeot Expert is robustly built, but certain areas are prone to rust, especially on older models or with intensive use in winter conditions. Check the wheel arches, bottom of the doors and the load floor for rust formation. Small paint damage should be treated immediately to prevent further rust.

The interior is functional and durable, but with heavy use seat upholstery, dashboard buttons and handles can show signs of wear. The sliding doors and rear doors have hinges and runners that must be lubricated regularly to keep them operating smoothly. Contamination or damage to these parts leads to creaking noises or sticking operation.

With combi versions with multiple seats it is important to check the anchorage points and rails of the seats. These must be firmly secured to guarantee safety. The Moduwork system with folding seats and through-loading hatch requires maintenance of the hinge points and locks.

Inspection tips for bodywork and interior

• Inspect wheel arches and doors for rust formation
• Lubricate hinges of sliding and rear doors regularly
• Check anchorage points of seats in combi versions
• Treat paint damage immediately to prevent rust
• Thoroughly test the hands-free function of the sliding doors

Prevent problems with proper maintenance

Preventive maintenance is the best way to minimise problems with the Peugeot Expert. The recommended service interval is every 20,000 kilometres or annually, whichever comes first. Always have maintenance carried out according to the manufacturer’s schedule, including replacement of engine oil, filters and fluids.

For diesel versions, regularly replacing the air filter and fuel filter is important to prevent engine problems such as contaminated injectors or EGR valves. Use quality fuel and consider a periodic fuel additive to keep the fuel system clean. For the electric e-Expert, maintenance is more limited, but have the brake fluid, coolant and air conditioning checked according to schedule.

Driving style also plays a role in component lifespan. Avoid aggressive driving, especially when fully loaded, and allow diesel engines to warm up before accelerating hard. This protects the turbo and extends the life of engine components. With the e-Expert, economical driving in Eco mode helps extend the range and preserve the battery.

Recognise symptoms and have them diagnosed in good time

Many problems with the Peugeot Expert announce themselves in advance with warning signs. The engine warning light on the dashboard indicates that fault codes have been stored in the system. Have these read immediately at a garage with professional diagnostic equipment. This prevents small problems from turning into expensive repairs.

Unusual noises such as knocking, banging, whistling or squeaking often indicate wear or defects in the suspension, engine or drivetrain. Do not ignore these signals, but have them checked. Vibrations in the steering wheel or body can indicate balance issues, suspension wear or problems with the driveshaft.

Changes in driving behaviour such as loss of power, increased fuel consumption, heavy steering or poor braking require immediate attention. These symptoms can have various causes and must be professionally diagnosed. Look for a specialist garage with experience of Peugeot commercial vehicles for the best diagnosis and repair.

What to look out for when buying a used Expert

The Peugeot Expert is popular on the used market, but it is important to check carefully before you buy. Always ask for the full service book and check whether all services have been carried out according to schedule. A complete service history provides certainty about the condition of the vehicle and helps avoid surprises.

For diesel versions, check the operation of the EGR valve, turbo and injectors. Ask the seller whether these components have recently been replaced or cleaned. Thoroughly test the engine when cold and warm, listen for unusual noises and watch for smoke from the exhaust. For the e-Expert, the condition of the battery is important. Ask about the remaining battery range and have it tested if desired.

Thoroughly test all electrical functions: lighting, central locking, sliding doors, rear doors, windows, air conditioning and the infotainment system. Also try all safety systems such as parking sensors, cameras and driver assistance systems. Faulty electronics can be expensive to repair.

Checklist for pre-purchase inspection of a used Expert

• Check the service book for completeness
• Test the engine on a cold and warm start
• Listen for unusual engine noises
• Inspect bodywork for rust and damage
• Test all electrical functions and systems
