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.
Van with minimal engine
112 hp in the heavy 3008 I is under-engined. The vehicle's weight of over 1,400 kg constantly overwhelms the small DV6.
Engine Weaknesses 6
The 1.6 HDi is notorious for repeated turbocharger failures. Soot particles in the oil alter viscosity, oil lines coke up and the turbocharger runs dry. A second failure after replacement without addressing the root cause is common.
Symptoms: Whistling from the turbocharger, severe power loss, blue or black exhaust smoke, oil leaking from turbo, engine enters limp mode
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 cam-to-cam timing chain between inlet and exhaust camshafts can stretch or snap. Hydraulic chain tensioners fail, causing valve timing shift and in extreme cases engine damage.
Symptoms: Rattling on cold start, rough engine running, engine management light, power loss, in extreme cases sudden engine shutdown from chain snap
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 6
A faulty component in the 1.6-litre diesel engine (DV6F) can cause sudden stalling while driving. In some cases the car briefly accelerates before suddenly stopping.
The 3008 T84 frequently suffers from defective sensors that cause permanently active warning lights in the cockpit. Various systems such as tyre pressure sensors, parking sensors and engine sensors are affected.
Heating problems occur particularly on 3008 models from 2011 onwards. The lifespan of the heating components is limited; first faults often appear after 60,000 to 90,000 km.
On the first-generation 3008 starting problems occur from as early as 30,000 to 50,000 km. Symptoms range from complete failure to start through to weak starter motor cranking.
Vehicles produced from April 2011 to May 2015 are affected by contact corrosion in the electrical connectors. This can lead to sporadic failures of various electrical systems.
The electric door mirrors on the 3008 T84 can fail between 50,000 and 100,000 km. Both the manual and automatic folding function can be affected.
