2.0 TDI vs 2.3 dCi (M9T): which engine is more reliable?

According to our risk index, the 2.3 dCi (M9T) carries less risk than the 2.0 TDI: 32/100 versus 48/100 (both moderate 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 2.3 dCi (M9T) has 2 documented serious faults, the main one being «Clogged or broken EGR valve damaging the turbo».

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 2.3 dCi (M9T) reliable?

The 2.3 dCi M9T is a van diesel with good durability if maintenance is kept up. The weak points cited are the EGR and the turbo, the injectors, and the particulate filter in urban use; the sources are mostly opinion websites.^[7][8]
