1.6 HDi 110 16V DPF (DV6TED4, 2004-2011) engine: faults and reliability

PSA/Ford 1.6 HDi, e-HDi, TDCi and BlueHDi (DV6) version

With caution

It is the version with the most complaints in the family (turbo, injection, EGR, DPF and dual-mass flywheel). It is only worth it with demonstrable maintenance and, if the turbo has already been replaced, with the complete cleaning procedure documented on the invoice.[1][2][3]

What changes in this version

Higher-output version of the first generation: Garrett GT1544V variable-geometry turbo and dual-mass flywheel (the 90 hp has a solid flywheel). The Euro 4 variant (9HZ) has a particulate filter, which on PSA diesels works with an additive.[2][4][5][6]

Engine codes of this version: 9HY, 9HZ, DV6TED4.

Faults of the 9HY engine

The documented engine faults that affect this version and its years, from most to least important.

  1. 1High severityFrequency: Very frequentTurboTurbo failure through lack of lubrication (carbon deposits and union filter)On the 16-valve 1.6 HDi/TDCi engines (2004-2011) the turbo can seize because carbon deposits from the oil clog the mesh filter in the union that feeds it. It is a serious, repeat fault: if only the turbo is replaced without cleaning the circuit, it fails again.Repair (garage): €700–€1,050
  2. 2High severityFrequency: Very frequentTimingTiming belt failure and premature wearOn the 8-valve 1.6 HDi/e-HDi 112/115 built between October 2010 and September 2011 the belt could break and leave the car stranded. PSA covered the repair and in 2014 preventively replaced the belt and crankshaft sprocket on those that had passed 120,000 km.
  3. 3Medium severityFrequency: CommonInjectionLeaks at the injector washers and carbon build-up in the cylinder headIt is common for the copper washers of the 1.6 HDi injectors to stop sealing: the engine blows gases, carbon forms around the injector and soot gets into the oil. It is cheap to repair, but if left it contaminates the oil and is one of the causes of turbo failure.Repair (garage): €110–€310
  4. 4Medium severityFrequency: CommonEmissions controlAdditive-fed particulate filter (Eolys cerine): depleted additive and cloggingThe DPF on the 1.6 HDi and BlueHDi works with an additive (cerine) that runs out at 80,000-120,000 km and has to be topped up for around €100-120 (price in Spain). With a lot of town use the filter clogs and the warning appears; if it is left, a new DPF costs around €1,500.Repair (garage): €100–€1,500Appears at around 80,000 km
  5. 5Medium severityFrequency: CommonEmissions controlDirty EGR valve and EGR cooler leaksThe 1.6 HDi EGR valve gets dirty easily, especially in town use, and causes jerking and stalling at idle. On the 8V engines the EGR cooler also fails, consuming coolant with no visible leaks.
