1.6 TDI vs 2.2 dCi and 3.0 dCi V6: which engine is more reliable?

According to our risk index, the 1.6 TDI carries less risk than the 2.2 dCi and 3.0 dCi V6: 45/100 versus 46/100 (both moderate risk). The 1.6 TDI has 2 documented serious faults, the main one being «Timing belt and water pump»; the 2.2 dCi and 3.0 dCi V6 has 2 documented serious faults, the main one being «3.0 dCi V6 overheating and expansion tank failures».

Is the 1.6 TDI reliable?

It depends on the generation. The EA189 (2009-2015, 75-105 hp) is one of the dieselgate engines: it needs the software update and, unlike the 2.0 TDI, an air flow stabiliser, on top of the typical EGR, particulate filter and turbo faults. The later EA288 (from 2012, 80-120 hp) is not singled out by the scandal, but it shares the need to keep an eye on the timing belt and the water pump.^[1][2][3][4]

Is the 2.2 dCi and 3.0 dCi V6 reliable?

Renault's big 2000s diesels, the 2.2 dCi (G9T) and the 3.0 V6 dCi (P9X), have a poor reputation among owners: big-end bearing failures are cited on the 2.2 and overheating on the V6. The sources are mainly forums and the press that reports them, with no official statistics.^[5][6][7]
