- 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.
