Engine Overview
The Peugeot 307 T5 is available with 5 engine variants — from 54 to 181 hp.
PSA entry-level diesel (1.4L HDi, 50 kW) with common-rail injection and timing chain. Frugal and fundamentally reliable, but with a well-known KP35 turbo issue: the oil feed line to the turbocharger clogs with soot deposits in the oil, and the banjo bolt with its filter screen (037649) blocks up. Injectors seize due to copper seal wear. With regular oil changes and long-distance driving, this engine lasts well.
- !! Injectors seized in the cylinder head from 150,000 km
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 - !! Turbo failure from clogged oil feed from 130,000 km
The oil feed line to the KP35 turbo clogs with soot deposits. The banjo bolt with integrated mesh filter (PSA 037649) blocks and cuts off lubrication. The turbo overheats and bearing shells are destroyed.
Symptoms: Whining noise from turbo, dropping boost pressure, blue smoke from exhaust, engine warning light. - !! EGR valve soots up and jams from 100,000 km
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
+ 5 more engine weaknesses + vehicle weaknesses
The most common PSA diesel (1.6L HDi, 68-85 kW), evolving through many stages from Euro 4 to Euro 6. THE defining problem is the turbocharger: the oil feed line clogs with soot particles and kills the TD025/GT1544V turbo — sometimes as early as 50,000 km. Injector seals, EGR carbon buildup, and DPF issues on short trips are additional trouble spots. With regular oil changes and highway driving, it remains a frugal, long-lasting engine.
- !! Turbocharger total failure from oil sludge from 100,000 km
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 - !! Leaking injectors with diesel in the engine oil from 120,000 km
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 - !! Premature camshaft and chain wear from 130,000 km
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
+ 5 more engine weaknesses + vehicle weaknesses
Powerful PSA diesel (2.0L HDi, 100-133 kW) for mid-size cars and SUVs. Common-rail with turbo, later versions as BlueHDi with SCR catalyst and AdBlue. Fundamentally robust and long-lasting with high torque. Injectors and the turbocharger are the main wear items. Timing belt with water pump should be replaced at least every 160,000 km. DPF regeneration becomes problematic with short-trip driving patterns.
- !! Timing belt snap caused by defective water pump from 90,000 km
The plastic impeller of the water pump can disintegrate from as early as 50,000 km. Fragments enter the timing belt drive and cause the belt to snap with subsequent total engine destruction.
Symptoms: Coolant temperature rises unusually, coolant loss without visible leak, faint grinding or squealing from the timing belt drive, sudden engine shutdown when belt snaps - !! Dual-mass flywheel wear from 130,000 km
The dual-mass flywheel wears prematurely, especially on the 107 hp variant. Oil dilution from DPF regeneration accelerates wear. The clutch should always be renewed at the same time.
Symptoms: Squealing or clattering when starting and stopping the engine, pronounced vibrations at idle, juddering when pulling away, knocking at low revs under load - !! Leaking injectors causing oil dilution from 140,000 km
Leaking injectors allow diesel into the engine oil, drastically reducing its lubricity. The rising oil level is often overlooked. This can cause piston and bearing damage.
Symptoms: Diesel smell at the dipstick, oil level rises above maximum, strong exhaust smell inside the car, engine judders or knocks more than usual, increased fuel consumption
+ 6 more engine weaknesses + vehicle weaknesses
Proven 16V naturally aspirated engine (1.6L, 80-88 kW) with decent power for the compact class and small MPVs. Timing belt every 120,000 km — if it snaps, the engine is destroyed (interference design). Throttle body and idle air control valve get dirty regularly. Ignition coil pack can fail at high mileage. The TU5JP4 with 110 PS in the 206 S16/RC is significantly sportier and correspondingly more stressed.
- !! Timing belt snap causing engine destruction from 120,000 km
The TU5 is an interference engine — if the timing belt snaps, pistons hit valves. Change interval is 120,000 km or 10 years, but is frequently missed. Always ask for proof of belt change when buying used.
Symptoms: Engine suddenly dies and will not restart, metallic crashing noise when attempting to start - ! Valve stem seals worn from 130,000 km
From around 130,000 km the valve stem seals tend to harden. Oil enters the combustion chamber, especially visible as blue smoke on cold start. Oil consumption rises to 0.5–1 L/1,000 km.
Symptoms: Bluish smoke on cold start, increased oil consumption, oil film on spark plugs - ! Thermostat and cooling system leaks from 100,000 km
The plastic thermostat housing becomes brittle over time. Coolant hoses near the water pump are prone to cracking. Engine fails to reach operating temperature or overheats when the thermostat fails.
Symptoms: Engine does not reach operating temperature (stays around 75°C), coolant loss, heater stays cold
+ 3 more engine weaknesses + vehicle weaknesses
Large 2.0-liter naturally aspirated engine (100-103 kW) with 16V technology from the EW family. A timing belt engine, fundamentally robust and powerful. The EW10J4 with 140 PS in the sporty version (206 RC, 307) runs under significantly higher stress. Timing belt replacement with water pump every 120,000 km at the latest — if it snaps, the engine is destroyed. The throttle body gets dirty regularly. A reliable engine with proper maintenance.
- !! Ignition coil failure from 80,000 km
The ignition coils of the EW10 fail regularly and cause misfires. On the 206 there was even a TSB with a wiring modification (capacitor on the connector). Individual cylinders drop out.
Symptoms: Juddering under acceleration, engine management light, increased fuel consumption, rough idle - !! Camshaft sensor failure from 90,000 km
The camshaft position sensor of the EW10 is prone to dirty contacts and intermittent failures. The engine can stall under throttle and requires careful application of the accelerator.
Symptoms: Engine stalls when blipping the throttle, warm-start problems, sporadic fault codes - !! Electric thermostat defective from 80,000 km
The electric thermostat of the EW10A fails frequently and causes overheating issues or too-low operating temperature. Converting to a mechanical thermostat is a well-known workaround.
Symptoms: Temperature gauge fluctuates significantly, engine does not reach operating temperature, overheating warning
