Peugeot 3008
Most widespread PSA diesel. Went through many evolution stages from Euro 4 to Euro 6. Economical and long-lived with regular servicing. Prone to DPF issues in short-trip operation.
Too weak for the SUV
100 hp in the 1,500 kg SUV 3008 II is wholly inadequate. The engine is overwhelmed; the driving experience is frustrating.
Engine Weaknesses 4
The copper sealing rings on the injectors wear out, allowing combustion gases and diesel to enter the cylinder head. Oil dilution by diesel can lead to engine damage. Affects all 1.6 HDi variants.
Symptoms: Diesel smell at the dipstick, rising oil level, black deposits around injectors, rough engine running, hissing noises at the cylinder head with engine running
The plastic impeller on the water pump breaks away early and can damage the timing belt or cause engine failure. Engine damage documented from as low as 70,000–88,000 km. Always replace the water pump at the same time as the timing belt.
Symptoms: Engine overheating, timing belt snaps without warning, fan noise, coolant loss
During short-trip use DPF regeneration fails regularly. Deposits in the EGR and throttle body additionally prevent correct regeneration. From 160,000 km complete replacement is frequently needed.
Symptoms: Warning 'particulate filter filling up', noticeable power loss, increased fuel consumption, engine judders under acceleration, limp mode
Leaks around the injector sealing area let exhaust gases into the cylinder head. A gel-like oil residue forms in the head chambers (especially pre-2006 build). Professional cleaning takes around 10 labour hours. Turbo damage threatened by oil contamination.
Symptoms: Turbo damage, power loss, black oil paste around injectors, engine oil contamination
Vehicle Weaknesses 8
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 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.
Plastic trim panels and decorative strips in the 3008 P84 interior can start rattling. The dashboard, door trim panels and centre console are particularly affected.
