Peugeot 3008

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

On 3008 models produced from April 2016 to August 2017 the fuel line can chafe against the aerodynamic cover of the fuel tank. The line can be damaged, allowing fuel to escape and ignite.

A potentially defective bolt connection on the front left or right ball joint bracket can lead to a bolt fracturing. This significantly impairs driving stability.

The 1.2 PureTech engine with wet-belt has been recalled multiple times. Poor maintenance and short-trip use cause the oil additives to break down prematurely, degrading the belt. Belt failure leads to engine damage. Affects model years 2017–2020.

Electrical problems are a frequent weak point on the 3008 P84. Failed touchscreens, defective sensors and central locking failures are regularly reported.

The EAT8 automatic gearbox in the 3008 P84 can display unusual shift behaviour in 2nd and 3rd gear. Jerky gear changes, delayed shifts and gearbox warning messages are reported.

The 3008 P84 suffers from disturbances in the ABS and ESP systems where warning lights illuminate without any clear mechanical fault. Wheel speed sensors or ECU faults are often the cause.

From around 80,000–120,000 km, shock absorbers and wishbone rubber bushes on the 3008 P84 show wear. The vehicle weight (approx. 1,600 kg) loads suspension components more heavily than a regular car. Oil traces on shock absorbers are a wear indicator.

The A/C condenser on the 3008 P84 is mounted at the front and is vulnerable to stone chip damage. A damaged condenser causes refrigerant loss. Stone chip damage is often not covered by insurance.
