1.6 CRDi vs 2.0 TDI: which engine is more reliable?

According to our risk index, the 2.0 TDI carries less risk than the 1.6 CRDi: 48/100 (moderate risk) versus 70/100 (high risk). The 1.6 CRDi has 4 documented serious faults, the main one being «MHSG belt tensioner and crankshaft pulley failure (48V mild hybrid)»; the 2.0 TDI has 3 documented serious faults, the main one being «Oil pump failure on the pumpe-düse 2.0 TDI».

Is the 1.6 CRDi reliable?

The U2 D4FB (2009-2018) is a generally robust diesel if well maintained, with known turbo failures in the early units and timing chain problems from 120,000-150,000 km. Its successor, the Smartstream (U3 D4FE, from 2018), has a good reputation, except in the 48V mild hybrid version, which has a belt tensioner and crankshaft pulley fault that can destroy the engine.^[1][2][3]

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.^{[4][5][6][7][8][9]}
