2.0 TDI vs 2.5 / 3.0 D-4D (KD): which engine is more reliable?

According to our risk index, the 2.0 TDI carries less risk than the 2.5 / 3.0 D-4D (KD): 48/100 (moderate risk) versus 63/100 (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 2.5 / 3.0 D-4D (KD) has 3 documented serious faults, the main one being «Cracked pistons in the 3.0 D-4D (1KD-FTV)».

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 2.5 / 3.0 D-4D (KD) reliable?

Toyota's KD diesels (2.5 D-4D, 2KD-FTV, and 3.0 D-4D, 1KD-FTV) have their best-documented weak points in the injectors: the copper seats of the 2004-2007 units, which can block the oil pickup, and the Denso injectors of the 3.0. The 3.0 of the Euro 4 era also has a record of cracked pistons; for the 2.5 we have only found the injector seal problem.^{[7][8][9][10][11]}
