2.0 TDI vs 1.9 dCi: which engine is more reliable?

According to our risk index, the 2.0 TDI carries less risk than the 1.9 dCi: 48/100 (moderate risk) versus 67/100 (high risk). The 2.0 TDI has 3 documented serious faults, the main one being «Oil pump failure on the pumpe-düse 2.0 TDI»; the 1.9 dCi has 3 documented serious faults, the main one being «Seizure and wear of the big-end bearings».

Is the 2.0 TDI reliable?

It depends on the generation. The EA189 (2008-2015) is the dieselgate engine: it needed a software update and has a record of EGR, particulate filter, turbo and injection faults. The earlier pumpe-düse (unit injector) engine has oil pump failures, and on the EA288 and EA288 evo (from 2012) the known faults are minor: coolant leaks and the odd AdBlue tank.^{[1][2][3][4][5][6]}

Is the 1.9 dCi reliable?

The 1.9 dCi (F9Q) was Renault's first common-rail diesel (1999) and powered a large part of its range, and those of Nissan and Volvo, for more than a decade. It has well-documented weak points: on versions of up to 120 hp built before 2005, the big-end bearings can seize and the turbo tends to degrade around 150,000 km; the injectors, the EGR valve and, on the 120 hp versions, the dual-mass flywheel also fail fairly often.^{[7][8][9][10][11]}
