Is the BMW M57 reliable?

The BMW M57 (1998-2010) is a six-cylinder diesel with a reputation for great mechanical longevity, capable of exceeding 500,000 km when well maintained, but a good share of the versions built before 2008 -especially with an automatic gearbox- have metal swirl flaps in the intake that can break and wreck the engine; check whether the car has them and what condition they are in before buying.^[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]
