Peugeot 207
PSA entry-level diesel with common rail injection. Economical and reliable, but low on power. Timing chain is maintenance-free.
Too weak for the 207
The 207 is heavier than the 206; the 70 hp are accordingly even less adequate. Economical, yes, but it's no fun to drive.
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 9
The manual gearbox on the 207 can develop rattling noises at low revs due to bearing wear, which worsen with increasing mileage. In the worst case a complete bearing failure leads to significant consequential costs.
The dual mass flywheel on the diesel and THP petrol engines wears at higher mileages and needs to be replaced together with the clutch. City driving and frequent pull-aways accelerate wear considerably.
Brake discs on the 207 wear twice as fast as average. TÜV/MOT inspectors flag the brakes above-average frequently. Both braking performance and the condition of the discs regularly attract negative attention.
Springs, shock absorbers and track rod ends on the 207 wear above-average quickly. From the second MOT/TÜV onwards, suspension faults become a problem. Seized bushes and joints on the front axle are typical.
The A/C often fails through a defective condenser or leaking compressor. Refrigerant loss through leaky seals is the most common cause. Sometimes the blower resistor also fails, preventing heater operation.
Vehicles built between 2009 and 2015 were recalled due to faulty seat heating cables. The defective cable can draw current when parked and drain the battery. Non-CC variants are also affected.
Electric window regulators often fail after 70,000 to 90,000 km, particularly at the rear windows. Worn motors or defective switches are usually to blame. This is among the most common electrical faults.
The 207's exhaust system is poorly protected against corrosion and rusts through above-average quickly. The rear silencer and flex pipes are particularly affected. TÜV/MOT inspectors flag the exhaust significantly more often than on comparable vehicles.
Failed bulbs and lighting problems are among the most common TÜV/MOT failures. Dipped beams, indicators and rear lights fail above-average frequently. TÜV inspectors flag lighting significantly more often than average.
