EGR cooler and bearings on the VM 3.0 V6 diesel (EcoDiesel)

Engine / equipment

VM Motori 3.0 V6 diesel (A630, “EcoDiesel”): Jeep Grand Cherokee and Gladiator, Chrysler 300C, Lancia Thema and Maserati Ghibli, Quattroporte and Levante

Period mentioned

2011 onwards

Symptoms

Coolant loss, white smoke or combustion in the intake manifold (cracked EGR cooler); deep metallic knock and the oil-pressure warning (bearings); on engines from 2020, low oil-pressure warnings or a failing high-pressure pump shedding metal.

Possible cause described

According to mechanics and owners, the EGR cooler cracks from thermal fatigue (Chrysler recalled it) and the crankshaft bearings can fail from lugging at low revs or carbon in the oil passages. On the third generation (from 2020) there was a recall for the Bosch CP4.2 fuel pump. Maserati uses the same VM engine in its diesels.

Check for the garage

Check the EGR-cooler and pump campaigns by VIN; watch the coolant and oil pressure; with knocking or the oil warning, stop. Avoid lugging the engine at very low revs under heavy load.
