2 known faults with sources

Engines: 2.0 / 2.2 (Petrol) · 2.0 / 2.2 HDi (Diesel)

Applies if: Twin MPV of the Citroën C8, Peugeot 807 and Fiat Ulysse (same base and engines).

Ball joints, rear tyres and belts on the C8, 807 and UlysseKnown weak points

Engine / equipment: Citroën C8, Peugeot 807 and Fiat Ulysse II (petrol and diesel)
Period mentioned: 2002–2014
Symptoms: Front suspension ball joints that fail (and replacement shortages); excessive rear tyre wear; serious build-quality problems. On the HDi: belts that break from windscreen water dripping onto their cover (2.2 HDi 2002–2007), a damped pulley to replace with the belt, water pump, particulate filter running out of additive and injectors seized in the 2.2 HDi cylinder head.
Possible cause described: According to Honest John, the rear wear was fixed under warranty with 16-inch wheels; Citroën later supplied new guttering with every C8 belt. On the Ulysse with Fiat engines, belt and pump are changed every 58,000–64,000 km. Ulysse recalls (2003): water in the airbag ECU, sliding-door locks, front brake hose and hub pin.
Check for the garage: Check ball joints and tyre wear; ask for the belt history; check campaigns by VIN.
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: 2.0 / 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.
