Peugeot 5008
Powerful PSA diesel for mid-size and SUV applications. Common rail with turbo. Later versions as BlueHDi with SCR cat and AdBlue.
Punchy family van
163 hp in the 5008 I: effortless even fully occupied. The best engine in the large van.
Engine Weaknesses 7
The plastic impeller of the water pump can disintegrate from as early as 50,000 km. Fragments enter the timing belt drive and cause the belt to snap with subsequent total engine destruction.
Symptoms: Coolant temperature rises unusually, coolant loss without visible leak, faint grinding or squealing from the timing belt drive, sudden engine shutdown when belt snaps
The dual-mass flywheel wears prematurely, especially on the 107 hp variant. Oil dilution from DPF regeneration accelerates wear. The clutch should always be renewed at the same time.
Symptoms: Squealing or clattering when starting and stopping the engine, pronounced vibrations at idle, juddering when pulling away, knocking at low revs under load
Leaking injectors allow diesel into the engine oil, drastically reducing its lubricity. The rising oil level is often overlooked. This can cause piston and bearing damage.
Symptoms: Diesel smell at the dipstick, oil level rises above maximum, strong exhaust smell inside the car, engine judders or knocks more than usual, increased fuel consumption
After switching off a hot engine the oil lines to the turbocharger can coke up. On the next start the turbocharger briefly runs without lubrication. Mainly affects the more powerful DW10 variants.
Symptoms: Increasing whistling or whining from the turbocharger, oil spots under the car in the turbo area, gradual power loss, blue smoke after the engine has been standing
Internal EGR cooler failure routes coolant into the exhaust gases. Coolant disappears without visible external leak. Repair requires 13.2 hours of labour. Cost 800–2,000 €.
Symptoms: Coolant drops without visible leak, white smoke from exhaust, heater won't warm up
The PSA-proprietary additive (Eolys) is mixed into the fuel and enables regeneration at a lower temperature. A defective additive pump or empty reservoir prevents regeneration and clogs the FAP prematurely. Change interval 120,000–180,000 km.
Symptoms: Warning 'particulate filter will soon clog', increased fuel consumption, power loss, regeneration attempts visible as idle speed fluctuations
The EGR valve seizes with soot deposits or no longer closes fully. The result is warning messages, poor cold-start behaviour and increased particulate output into the filter, causing it to clog faster.
Symptoms: Warning 'exhaust aftertreatment system fault', poor cold-start behaviour, light smoke when accelerating, occasional judder under load
Vehicle Weaknesses 7
The AL4 automatic gearbox in the 5008 T87 is the well-known PSA problem unit. Judder and shift anomalies occur. A regular oil change every 40,000 km is essential but is frequently skipped.
A thumping noise from the front axle is one of the most common weak points of the 5008 T87. Top mounts, shock absorbers and wishbone bushes wear comparatively early.
The turbocharger seal on the HDi diesel and THP petrol can develop leaks, leading to oil loss. In endurance testing the turbo seal was replaced at 99,036 km.
The A/C compressor on the 5008 T87 fails at higher mileages. On cars without regular A/C servicing the compressor seizes through internal wear. Compressor problems were documented in endurance testing.
The front brake discs on the 5008 T87 tend to develop lateral run-out and need replacing unusually early. In endurance testing the front discs were replaced due to run-out at just 30,885 km.
The interior of the 5008 T87 develops prominent rattles from trim panels, the centre console and doors with increasing mileage. Material quality is considered a weak point.
The vehicle is prone to sporadic warning messages without a concrete fault from just a few thousand kilometres. Sensor errors and infotainment failures are documented.
