From 2004 to 2011, the Peugeot DV6TED4 or 1.6 HDi 109 1.6-liter diesel engine was assembled and fitted to nearly all of the company’s well-known vehicles. This engine came in two versions: 9HY for Euro 3 and 9HZ for Euro 4 with a particulate filter.
DV6TED4, DV6ATED4, DV6BTED4, DV6CTED, DV6DTED, DV6ETED, DV6FCTED, DV6FDTED, and DV6FETED are additional diesels in the DV6 family.
The first diesel from the sizable 1.6 HDi family made its debut on the Peugeot 407 in 2004. This motor has a standard design with a 4-cylinder aluminum block with cast-iron sleeves, an aluminum head for 16 valves with hydraulic compensators, and a combined timing drive. The intake and exhaust shafts are already chain-connected, and a belt connects the crankshaft to the exhaust camshaft.
Here, the Bosch Common Rail system with electromagnetic injectors handles the injection. Every modification has an intercooler and a Garrett GT1544V turbine for supercharging. The motor torque is momentarily increased by 20 Nm in a number of versions’ Overboost mode.

Disadvantages of the DV6TED4 engine
The hydraulic chain tensioner, which is situated between the camshafts, was destroyed in the early years of production, and the camshaft cams wore down quickly. Over time, these units’ manufacturing quality has improved, and the issue has all but disappeared.
Particulate filter modifications included an air dispenser with two dampers that frequently leaked grease onto the timing belt and auxiliary units. Oil is frequently driven into the intake by the pneumodispenser of models without a particulate filter.
The Garrett GT15V turbine, which is dependable on other engines, performs suspiciously poorly here. A clogged coarse filter, which is found in the oil pipe fitting that provides lubricant to the turbocharger, is typically the reason for its early failure.
The particulate filter is short-lived, the refractory washers beneath the nozzles frequently burn out, the EGR valve becomes dirty and sticks very quickly, and when the timing belt breaks, the rockers break and the camshaft cams are damaged, just like in any modern diesel engine.
