Peugeot 3.0 V6
3.0L V6 from PSA. Smooth and dependable, but high fuel consumption. Timing belt replacement laborious and expensive.
V6 power in the family van
The 3.0 V6 makes the 807 the fastest van in its class. Effortless pull, but high fuel consumption tempers the fun factor.
Engine Weaknesses 6
Leaking camshaft or crankshaft seals allow oil to reach the timing belt. The oil degrades the rubber, the belt slips and valve timing shifts. Valve damage is a real risk.
Symptoms: Uneven engine running, compression loss on individual cylinders, engine warning light, in the worst case engine damage
The ES9 V6 is strongly prone to oil leaks at the camshaft covers. Escaping oil can reach the timing belt and cause belt slippage or even engine fire. Regular inspection is mandatory.
Symptoms: Oil spots in engine bay, oil smell, visible oil traces at cylinder heads, burning smell
The six individual ignition coils of the ES9 V6 are prone to failure, leading to misfires on individual cylinders. The problem often develops gradually.
Symptoms: Juddering at certain RPMs, engine management light, noticeable power loss, increased fuel consumption
The plastic thermostat housing and the difficult-to-access coolant line between thermostat and water pump become brittle and crack. Disassembly is extremely laborious due to poor accessibility.
Symptoms: Coolant loss, overheating on the motorway, temperature gauge above 110°C, steam escaping
The V6 3.0L valve stem seals harden and allow oil into the combustion chamber. Blue smoke on cold start is typical. Repair without removing the cylinder head is possible but laborious. On the V6: approx. 8 hours of fitting work.
Symptoms: Blue oil smoke on cold start, oil consumption 0.5–1 L per 1,000 km, spark plugs with oil film
Individual ignition coils fail at higher mileages. The V6 has 6 separate coils, which can explain sporadic cylinder misfires. Replacing individual coils is cheaper than a full set.
Symptoms: Engine misfires, engine judders under acceleration, misfire warning for individual cylinders
Vehicle Weaknesses 6
The BSI control unit of the 807 is extremely failure-prone. Moisture and corrosion in the central electronics area can cause a complete failure: window regulators, display, radio, wipers and central locking all fail simultaneously. Recoding is often required.
The notorious AL4 automatic gearbox of the 807 is known for jerky gear changes and limp modes. Defective solenoid valves and insufficient gearbox oil changes are the main causes. Regular oil changes every 40,000 km delay the problems.
Peugeot recalled 807 models because water could enter the vacuum system of the brake servo under certain conditions. This can significantly impair braking performance and create dangerous situations.
The electric sliding doors of the 807 are failure-prone. Defective drive motors and dirty guide rails cause malfunctions. The auto motor und sport long-term test documents sliding door electronic problems after short usage.
The auto motor und sport long-term test documents pronounced corrosion in the 807's engine bay after only a few years. Bumper mounting points and subframes rust through. Poorly fitting body panels accelerate paint loss and rust.
The long-term test documents pronounced interior rattles in the 807. Loose trim pieces on doors, dashboard and headlining produce irritating noises over road irregularities. A quality issue on early production years.
