Handbrake, ABS brakes and airbag on the Evasion and 806Known weak points

Engine / equipment: Citroën Evasion (Synergie) and Peugeot 806 (petrol and diesel)
Period mentioned: 1994–2002
Symptoms: A handbrake ratchet that can fail (built March to July 1998); air in the brake fluid on ABS cars (March–April 1999); an airbag trigger to be checked (September–October 1995). On diesels: water in the brake vacuum pump reducing assistance and leaks at the HDi common-rail unions.
Possible cause described: PSA recalls and technical bulletins collected by Honest John for the Synergie (British name of the Evasion), twin of the Peugeot 806.
Check for the garage: Test the handbrake and the pedal feel; 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: 1.9 TD / 2.0 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.
