The diesel version of the C1/107/Aygo triplets, built at the TPCA plant in Kolín alongside its petrol siblings. The PSA DV4TD engine is a compact turbodiesel that delivers outstanding fuel economy (3.8-4.2 L/100 km) and can comfortably exceed 250,000 km with regular oil changes. It is a manual-only model, avoiding the SensoDrive gearbox issues that plague the petrol variant. Main ownership concerns centre on turbo wear, injector seal leaks, and DPF clogging on cars used for short urban trips.· more· less
Exceptional diesel fuel economySimple mechanicals, cheap parts
Turbo and injector wear with ageDPF clogs on short-trip use
Buy if: You cover mostly longer drives, can find one with a complete service history and regular oil changes, and prefer a manual gearbox.
Avoid if: You mainly drive short urban trips (the DPF will clog) or the car shows signs of neglected oil changes and turbo smoke.

The small KP35 turbo fails when its oil feed line becomes blocked by carbon sludge · more· less
The DV4TD uses a compact KP35 turbocharger with a small-bore oil feed line. Over time, carbon deposits in the engine oil can restrict this feed line, starving the turbo bearings of lubrication. This typically occurs from 80,000-120,000 km onwards, especially when oil changes have been delayed beyond 15,000 km intervals. Symptoms include blue/white exhaust smoke, excessive shaft play, loss of boost, and increased oil consumption. A remanufactured KP35 turbo unit costs approximately €300-500 for the part, with €400-600 in labour. When replacing the turbo, the oil feed pipe and banjo bolts must also be renewed, and the sump cleaned of residual sludge. The crankcase ventilation membrane should be checked at the same time, as a failed membrane accelerates oil contamination. Regular oil changes (every 12 months or 15,000 km) with quality oil are the most effective prevention.
Injector seal leak and carbon buildup
up to €1,2002 of 6
Copper injector seals fail over time, causing combustion gas leaks and carbon deposits around injectors · more· less
The DV4TD's fuel injectors use copper crush washers that degrade with heat cycles. When these seals fail, combustion gases leak past the injector seat, creating thick carbon buildup visible around the injectors (typically most severe on the end cylinder). Early stages cause a slight diesel knock at idle. Advanced failures lead to hard starting, rough running, and loss of power. Replacing all four injector seals (copper washers, O-rings, and fire rings) costs approximately €200-350 at an independent garage. However, if the injector seats are badly carbonised, the seats need recutting, adding to the cost. If an injector itself is damaged, a replacement injector costs €200-300 each. A set of four can reach €800-1,200 fitted at a specialist.
DPF clogging from short trips
up to €1,2003 of 6
The diesel particulate filter blocks up when the car is used mainly for short urban journeys · more· less
The C1 1.4 HDi is fitted with a DPF that requires regular sustained driving (20+ minutes at motorway speeds) to passively regenerate. Cars used predominantly for short urban trips cannot reach the exhaust temperatures needed for regeneration, causing soot to accumulate until the DPF warning light illuminates. A forced regeneration at a garage costs €100-200. Professional off-car DPF cleaning runs €300-500. A replacement DPF costs €600-1,200 fitted, depending on whether aftermarket or OEM. Removing or disabling the DPF is illegal across the EU. Cars with documented regular longer journeys in their history are far less likely to have DPF problems.
Clutch cable stretch and failure
up to €4004 of 6
The mechanical clutch cable stretches over time and can eventually snap · more· less
The C1 uses a traditional cable-operated clutch rather than a hydraulic system. The cable stretches with use, initially causing the clutch biting point to rise higher on the pedal travel. Eventually the cable can snap entirely, leaving the car undriveable. This is a common issue on all Mk1 C1/107/Aygo models and typically occurs between 60,000-120,000 km depending on driving conditions (city driving with frequent gear changes accelerates wear). Adjustment can extend cable life temporarily. A replacement cable with fitting costs approximately €100-200 at an independent garage. If the clutch itself is worn (typically after 120,000-180,000 km), a clutch kit replacement costs €300-500 fitted, which is relatively cheap due to the simple transverse layout.
Crankshaft damper pulley deterioration
up to €4005 of 6
The rubber layer inside the torsional vibration damper pulley deteriorates and can disintegrate · more· less
The DV4TD engine uses a torsional vibration damper (TVD) pulley on the crankshaft. The internal rubber layer that absorbs vibrations deteriorates over time and with heat exposure. When it fails, the outer ring of the pulley can separate, causing accessory belt misalignment, loss of alternator charging, and potentially leaving you stranded. Early symptoms include unusual vibrations at idle and a slight wobble visible on the pulley. The part costs approximately €60-120 for an aftermarket replacement, with €80-150 in labour. This is a preventive item worth checking at every timing belt service.
Exhaust system corrosion
up to €6006 of 6
Rear silencer and catalytic converter joints rust through, particularly in wet/salty climates · more· less
The C1's exhaust system is known to corrode relatively quickly, particularly the rear silencer (backbox) and the joint between the exhaust manifold and catalytic converter. The catalytic converter itself can crack at the weld points due to thermal stress. Rear silencer replacement is straightforward at €100-200 fitted. A catalytic converter replacement costs €200-500 depending on whether a type-approved aftermarket unit (€150-250) or OEM part is used. Cars from coastal or salt-road regions are most affected. An exhaust inspection from underneath is an essential part of any pre-purchase check.
Reliable diesel when driven regularly, but needs attentive maintenance
The DV4TD engine is fundamentally durable and can exceed 250,000 km without major issues when given regular oil changes and sustained motorway use. The main risks are turbo oil starvation from sludged feed lines, injector seal degradation, and DPF clogging from short-trip use. All are preventable with good maintenance habits. The C1 is mechanically simpler than larger cars using the same engine, which helps keep repair costs low. Avoid cars with unknown service histories or evidence of predominantly urban short-trip use.
Service history
Complete records essential. Verify oil changes every 12 months or 15,000 km. Diesel engines punish neglected maintenance.
Tires
Check tread depth, age (date codes on sidewall), and uneven wear patterns. Small tires wear relatively quickly.
Cold start
Start the engine completely cold. Listen for any excessive rattling, knocking, or blue/white smoke.
Test drive
Drive for at least 20 minutes including varied speeds. The car should pull cleanly under acceleration with no hesitation.
Specific for this vehicle
Check turbo for smoke and shaft play
Accelerate hard from low rpm and check mirrors for blue or white exhaust smoke. Any visible smoke indicates turbo wear.
Inspect injector area for carbon buildup
Remove the plastic engine cover. Look for thick black carbon deposits around the injectors, especially the end cylinder.
Check DPF warning light and driving history
Verify the DPF light is not illuminated. Ask about the car's typical use: regular motorway driving is ideal.
+ 4 more checksShow less
Test clutch pedal feel and biting point
The biting point should be roughly mid-travel. A very high biting point indicates a stretched cable or worn clutch.
Inspect exhaust system from underneath
Look for rust holes in the rear silencer and cracked joints at the catalytic converter. Shake the exhaust to check for loose mounts.
Check boot area for water ingress
Lift the boot floor carpet and feel for dampness. Known leak points are the high-level brake light seal and rear light gaskets.
Inspect crankshaft pulley for wobble
With the engine running, visually check the front pulley for wobble or unusual vibration indicating rubber deterioration.
