Is the MZR-CD reliable?

The MZR-CD is Mazda's most widespread diesel between 2002 and 2013, fitted to the Mazda3, Mazda6, Mazda5 and CX-7. It is sensitive to short journeys: the injector seals and incomplete DPF regenerations can dilute the oil, and the EGR and intake build up carbon. The 2.2-litre redesign (from 2008), with a timing chain instead of a belt, adds the risk of that chain stretching and damaging the engine.^[1][2][3][4]

Is the D5 5 cilindros reliable?

Volvo's five-cylinder D5 (2.4 D3/D4/D5 and 2.0 D3/D4) has no documented systemic fault, but it does carry one serious risk: several owners report that a snapped auxiliary belt took the timing belt with it. The rest is EGR, DPF and the odd turbo.^[5][6][7]
