Peugeot 208 A9

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.

+ 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

+ 5 more engine weaknesses + vehicle weaknesses

Small 1.0-liter three-cylinder PureTech (50 kW) without turbo — the base engine option in the 208 A9. Frugal and adequate for city driving, but overwhelmed on the highway. Shares the oil-bathed timing belt (wet belt) design with the EB2 — the Stellantis warranty extension to 10 years applies here as well. Lower thermal stress without a turbo makes the wet belt somewhat more durable than in the turbocharged variants. Strict oil change intervals are essential.

• !! Oil-bath timing belt swells and disintegrates from 80,000 km

  The EB0 uses a timing belt running in an oil bath. Chemical additives in the engine oil attack the rubber — the belt swells, sheds fibres and blocks oil channels. In extreme cases engine damage from oil pressure loss. Stellantis has extended the warranty to 10 years/175,000 km.

  Symptoms: Oil pressure warning, metallic noises, engine power loss, coolant possibly contaminated with oil; often no warning before total failure

• !! Increased oil consumption from 90,000 km

  The EB0 tends towards excessive oil consumption, especially when unapproved engine oil is used. Incorrect oil specification can lead to piston ring coking. Regular oil level checks and oil changes every 10,000 km are mandatory.

  Symptoms: Oil level warning between services, slight blue smoke on cold start, oil consumption above 0.5 L/1,000 km

+ 2 more engine weaknesses + vehicle weaknesses

Naturally aspirated variant of the 1.2-liter PureTech three-cylinder (56-60 kW). Simple technology without turbo, a solid base engine for city driving. Shares the inherently problematic oil-bathed timing belt design — Stellantis extended the warranty to 10 years/175,000 km. With regular oil changes (max. 15,000 km intervals) and some highway driving mixed in, this is an uncomplicated engine. Later production years from around 2022 onward use a timing chain instead.

• !! Wet belt (oil-bath timing belt) premature wear from 80,000 km

  The naturally aspirated EB2 also uses an oil-lubricated timing belt (wet belt). When oil changes are neglected or the car is used mainly for short trips the oil degrades faster, the belt swells and starts to break up. Rubber particles clog the oil pump strainer and VVT solenoid valves. In the worst case the belt snaps and pistons hit valves — total engine failure.

  Symptoms: Engine management light, rough running, oil pressure warning, sudden engine shutdown

• !! Crankshaft axial play from weak thrust washers from 100,000 km

  The crankshaft thrust washers (half-rings) are undersized and wear prematurely. When axial play exceeds 0.5 mm the timing belt can jump off its sprockets — valves collide with pistons and the cylinder head is destroyed. The thrust washers are not available separately; the entire block must be replaced.

  Symptoms: Knocking noises when pressing and releasing the clutch, engine rattling, sudden catastrophic engine failure

• !! Crankshaft thrust washers wear quickly from 90,000 km

  The crankshaft thrust washers wear particularly quickly and cause axial play. From 0.5 mm of axial play Stellantis recommends replacing the complete engine block. Affects all EB2 generations up to build year 2022. Repair costs potentially 2,000–8,000 Euro.

  Symptoms: Vibration at idle, metallic knock on load changes, oil pressure warning, engine noise that varies with rpm

+ 4 more engine weaknesses + vehicle weaknesses

Compact 1.4-liter naturally aspirated engine (70 kW) from the Prince family — a PSA/BMW joint development. Timing chain instead of a timing belt, but the chain stretches from around 80,000 km when oil changes are neglected. Oil consumption from piston ring wear is the second known weakness. Intake valves develop carbon buildup from oil mist deposits. The plastic thermostat housing cracks. With careful maintenance, a frugal and long-lasting engine.

• !! Timing chain stretch and tensioner failure from 100,000 km

  The Prince engine suffers timing chain stretch from defective tensioners. Rhythmic rattling from the driver's side is a warning sign. A jumped chain risks severe valve damage.

Revised THP with 156 PS (115 kW) — slightly more powerful than the EP6DT. The timing chain remains the main problem: a full chain kit replacement costs 1,000-4,000 EUR depending on the extent of damage. Piston ring coking leads to increased oil consumption starting from 50,000 km. VVT solenoid valves clog from oil degradation. The turbocharger (Borgwarner K03) and high-pressure fuel pump are additional cost drivers. Only operate with short oil change intervals.

• !! Timing chain stretch and tensioner failure from 80,000 km

  The hydraulic chain tensioner jams or fails; the chain stretches from around 70,000–90,000 km. Rattling on cold start that briefly subsides after warm-up. Continued operation risks catastrophic engine damage from incorrect valve timing.

  Symptoms: Rattling on cold start at around 2,000–3,000 rpm, disappears after warm-up. In advanced stage: rattling on every cold start, engine management light

• !! Increased oil consumption due to coked piston rings from 80,000 km

  Piston rings coke up from deposits and lose their sealing effect. Oil consumption of 1 L/5,000 km is still considered normal by PSA; consumption above 1 L/1,000 km indicates compression problems. Poor oil quality or long oil change intervals are often the cause.

  Symptoms: Blue exhaust cloud on cold start or under load, dropping oil level between change intervals, smoke when revving

• !! High-pressure pump wears out prematurely from 90,000 km

  Design weakness of the HP pump: excessive pressure against the shaft seal leads to premature wear. Fault code P0087 (rail pressure too low) is the typical result. PSA acknowledged the problem and offered goodwill coverage up to 150,000 km / 7 years.

Most powerful THP variant (1.6L, 153 kW/225 PS) for the 208 GTi by PS and RCZ R. Revised twin-scroll turbo technology with significantly more torque than the base THP. The timing chain was improved compared to early THP variants but remains a concern at high mileage. HPFP seals and VVT solenoid valves wear faster under the high load. Valve carbon buildup from direct injection is inherent to the design.

• !! Timing chain stretch under extreme turbo load from 100,000 km

  The EP6FADTX is the most highly loaded variant of the Prince family (225 hp). Despite the improved chain, stretch occurs from around 100,000 km. The start-stop system generates additional load cycles on the chain.

  Symptoms: Chain rattle on cold start, rough engine running, valve timing fault in OBD, power loss; if chain jumps: catastrophic damage
