Peugeot 2008
PSA entry-level diesel with common rail injection. Economical and reliable, but low on power. Timing chain is maintenance-free.
SUV looks without SUV power
68 hp in the pseudo-SUV 2008: heavy, wind-resistant, zero pulling power. The styling promises more than the engine delivers.
Engine Weaknesses 6
The injectors on the DV4 can seize in the injector bore due to carbon deposits and corrosion, making them impossible to remove without destruction. Forced removal risks damage to the cylinder head.
Symptoms: Increased fuel consumption, rough idle, black or white smoke from exhaust, engine management light, power loss under acceleration
The EGR valve on the DV4 soots up heavily from carbon deposits, particularly during frequent short-trip use. Adaptation after replacement requires PSA diagnostic software (PP2000).
Symptoms: Engine warning light, noticeable power loss, rough engine under part load, elevated emissions, rough idle, fault codes P0409/P0490/P1459
The DPF on the DV4 blocks up during predominantly short-trip use because exhaust temperatures for regeneration are never reached. Ash accumulates and can permanently clog the filter.
Symptoms: DPF blocked warning on instrument cluster, significant power loss, increased fuel consumption, engine enters limp mode, exhaust smell inside the car
Defective thermostat won't open correctly: engine stays below operating temperature in city traffic or overheats. The cooling fan relay/thermostat can also fail. Repair cost 80–250 € including parts.
Symptoms: Temperature gauge fluctuates wildly, engine overheats in city/stationary, cooling fan cycles intermittently
The injector copper seal fails: exhaust gases escape from the combustion chamber, a sticky black deposit forms around the injector. Carbon deposits in the cylinder head are dangerous for the turbo. Repair cost approx. 450–900 €.
Symptoms: Sticky black soot deposit visible around injectors, burnt oil smell, occasional warm-start failure
The oil feed gallery sits too close to the outer edge: the head gasket tends to leak on the timing side. Symptoms similar to the TU engine. Worth addressing during a timing belt change.
Symptoms: Oil film on the front timing side, slight oil loss, oil smell from the engine bay
Vehicle Weaknesses 6
On PureTech 110/130 models (03/2013–04/2017) timing belt wear particles can affect the vacuum pump and impair brake servo function.
All model years of the 2008 I stand out at inspection with above-average brake disc wear. Pads and discs need replacing more frequently than on competitors.
The exhaust system on the 2008 I shows a clearly above-average defect rate at inspection. Leaks and corrosion at the joints appear earlier than on competitors.
Track rod ends and ball joints on the 2008 I wear at higher mileages and get flagged at inspection. Cars used predominantly on rough roads are affected earlier.
Headlight alignment on the 2008 I fails inspection above-average rates. The headlight levelling system and bulbs show premature failure.
The exhaust system on the 2008 I shows an elevated defect rate at inspection due to corrosion. The rear silencer and centre pipes are particularly susceptible, especially on cars predominantly used for short trips.
