2 known faults with sources

Engines: 1.6D / D2 / 2.0D / D3 / D4 (Diesel)

Applies if: Only the 2.0D: it is PSA and Ford’s 2.0 diesel (2.0 HDi / 2.0 TDCi); it does not apply to Volvo’s five-cylinder diesels (D3, D4, D5).

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.

Engines: 1.6D / D2 / 2.0D / D3 / D4 (Diesel)

Applies if: Only the 1.6D / D2: it is PSA and Ford’s 1.6 diesel (1.6 HDi / 1.6 TDCi); it does not apply to Volvo’s five-cylinder diesels.

1.6 TDCi turbo starved of oilInjection / turbo
Engine / equipment
1.6 TDCi (DV6)
Period mentioned
Approx. 2004–2018
Symptoms
Hissing from the engine, diesel smell in the cabin, very dark oil between changes and, eventually, a failing turbo with smoke and loss of power.
Possible cause described
The injectors’ copper washers stop sealing; the gases form carbon that gets into the oil and blocks the mesh filter in the turbo oil-feed pipe, starving the turbo. The wrong oil and switching off with the turbo very hot make it worse.
Check for the garage
Check the injector washers and the turbo oil-feed filter. If the turbo is replaced, also clean the sump, intercooler and feed pipe, or the new turbo can fail again. Use low-SAPS oil.
Cost cited in the source
Approx. €1,200–2,500 for a turbo replacement with oil-circuit cleaningA rough figure from the original database, not an up-to-date quote.
