3 known faults with sources

Engines: 1.6 / 2.4 (Petrol)

Applies if: Only the 4008 1.6 (2012–2017); the 2.4 is a different engine.

Sticking piston rings, oil consumption and timing chain on the Mitsubishi 1.6 (4A92)Engine

Engine / equipment: Mitsubishi 117 hp 1.6 petrol (4A92): Citroën C4 Aircross and Peugeot 4008 (also the Mitsubishi ASX)
Period mentioned: 2012–2017
Symptoms: Oil has to be topped up between changes; bluish smoke; chain rattle on cold starts.
Possible cause described: Russia’s Za Rulem magazine (2021) rates the 4A92 the least successful engine of the range: the piston rings tend to stick from as early as about 80,000 km, which raises oil consumption; the timing chain can stretch beyond 100,000 km, and the engine is very sensitive to the oil level, which should be kept at least halfway up the dipstick.
Check for the garage: Measure oil consumption between changes and check the level often; listen for the chain on a cold start; ask for the oil-change history.
Cost cited in the source: No verified estimate; ask the garage for a quote.A rough figure from the original database, not an up-to-date quote.

Engines: 1.6 / 2.4 (Petrol) · 1.6 / 1.8 / 2.2 HDi (Diesel)

Applies if: Only the 4007 (2007–2012), twin of the C-Crosser; the 4008 is a different car.

Clutch, ABS/ESP module and crankshaft seal on the C-Crosser and 4007Known weak points

Engine / equipment: Citroën C-Crosser and Peugeot 4007 (Mitsubishi 2.4 petrol and 2.2 HDi)
Period mentioned: 2007–2012
Symptoms: A failing Teves ABS/ESP module (expensive repair); clutch and dual-mass flywheel failing when towing because 1st and 2nd are tall; a weak battery (warned by a “gong”). On the 2.2 HDi: a crankshaft seal that leaks oil onto the clutch (which slips, also on the DCS gearbox) and the Eolys particulate-filter additive bag exposed next to the rear wishbone.
Possible cause described: They are twins of the Mitsubishi Outlander. Cases collected by Honest John; the maker often paid part of the ABS/ESP and clutch repairs.
Check for the garage: Check the clutch does not slip; read the ABS/ESP fault memory; test the battery.
Cost cited in the source: No verified estimate; ask the garage for a quote.A rough figure from the original database, not an up-to-date quote.

Engines: 1.6 / 1.8 / 2.2 HDi (Diesel)

2.0/2.2 HDi DPF, EGR, turbo and flywheelDPF / EGR / turbo / flywheel

Engine / equipment: PSA 2.0 HDi (DW10) and 2.2 HDi (DW12), including the 2.0/2.2 JTD in the Fiat Ulysse and Scudo and the Lancia Phedra
Period mentioned: 1998–2015
Symptoms: Particulate filter warning and power loss; rough idle from a dirty EGR; vibration and knocks when starting or in low gears (dual-mass flywheel); smoke or hesitation from injectors at high mileage.
Possible cause described: The engine itself is very robust, but the ancillaries are not: the DPF with Eolys additive clogs in town use, the EGR and its cooler fill with soot, the variable-geometry turbo sticks and the dual-mass flywheel wears. The 136 hp versions have more problems than the 138 to 163 hp ones.
Check for the garage: Read the DPF status and additive level, check the EGR and cooler, check the dual-mass flywheel at start-up and measure injector balance rates.
Cost cited in the source: Forced DPF regeneration: €100–150; new DPF: €800–1,500; rebuilt injector: €200–250A rough figure from the original database, not an up-to-date quote.

Mileage cited in the database: 120,000–180,000 km. This is not a maintenance interval and does not predict a failure.
