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

According to our risk index, the 2.0 TDI carries less risk than the 1.9 TDI: 48/100 (moderate risk) versus 66/100 (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 TDI has 3 documented serious faults, the main one being «Big-end bearing failure».

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 TDI reliable?

It depends a lot on the version. The rotary pump (1996-2003, codes ALH and AGR among others) has a reputation for great durability. The unit injector system (1999-2010) improves performance and emissions, but has more documented faults: dual-mass flywheel, turbo, EGR valve and, above all in the 105 hp version, cases of broken big-end bearings.^{[7][8][9][10][11][12][13]}
