1.6 CRDi vs 2.0 DTI and 2.2 DTI: which engine is more reliable?

According to our risk index, the 2.0 DTI and 2.2 DTI carries less risk than the 1.6 CRDi: 38/100 (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 DTI and 2.2 DTI has 2 documented serious faults, the main one being «VP44 injection pump and air mass meter failure».

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 DTI and 2.2 DTI reliable?

The 2.0 DTI and 2.2 DTI (X20DTH/Y20DTH and Y22DTR) are the direct-injection diesels with a Bosch VP44 pump that Opel fitted between 1997 and 2005 to the Astra G, Vectra B and C, Zafira A, Signum and Omega B. German Wikipedia documents recurring VP44 pump and air mass meter failures in its early years, and a German used-car buying guide singles out the EGR valve as its main weak point even once the engine had matured, in the Vectra C.[4][5]
