Peugeot 2008 A94

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

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

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
