Frequently asked questions
Which Opel Astra L engine is the most reliable?
1.5 BlueHDi (DV5) — Maint. Sensitive verdict. The 1.5 BlueHDi (DV5 — shared across the 308/Corsa F/2008/Grandland) is the frugal long-distance Astra L and a much less anxious buy than the PureTech petrol. Standard modern-diesel cautions: DPF clogging on short trips, EGR sooting, the AdBlue/SCR system (a known fault area on this generation — sensor/pump issues), injector wear, and the timing belt (the DV5 had wet-belt attention on some cars, so verify belt history). A motorway-driven, on-schedule car is dependable and economical; buy on belt, DPF and AdBlue history.
