Cheap Vauxhall Astra Sump

This spans the Astra H (2004–2010) and Astra J (2009–2015) generations, so the two cars are from different platforms and the sumps are very unlikely to be interchangeable. The most reliable way to confirm is to supply the breaker with your engine code, which you'll find on your V5C or via a VIN check. Never assume a fit based on year alone across a generation boundary.

Both years sit within the Astra J generation (2009–2015), so fitment is driven primarily by engine code rather than the model year. Match the engine code exactly — a 1.4 turbo sump, for example, is not the same as a 1.6 CDTi sump even within the same generation. Share your engine code with the breaker to confirm, as there can be mid-run changes to ancillary mounts that are worth verifying against your specific registration.

Trim level makes no difference to sump fitment — the SE and SRi use the same sumps when they share the same engine code, because the sump is a mechanical component tied to the engine, not the badge. The engine code is what the breaker will use to source the correct part, so check yours on your V5C before getting quotes. You may find cosmetic differences in the engine bay between trims, but these don't affect which sump fits.

No — petrol and diesel engines are completely different units and their sumps are not interchangeable, even within the same generation and model year. Always specify your fuel type alongside the engine code when contacting a breaker. The engine code is the definitive guide here and will immediately tell the breaker which sump family they're working with.

Both years fall within the Astra H generation (2004–2010), so there is a reasonable chance of compatibility if the engine codes match, but there was a facelift in 2006 and running production changes mean ancillary and mounting details can vary. You should confirm fitment with the breaker by providing your full engine code and registration, rather than relying on year alone. This is especially important for sumps, where sump rail profiles and sensor bosses can differ between production runs.

The single most important detail is your engine code, which you'll find on your V5C logbook or through a VIN check — it's more useful than the year or trim name because sumps follow the engine, not the badge. Also tell the breaker your fuel type, gearbox type (manual or automatic), and the model generation if you know it (for example, Astra J 2009–2015). The more precise you are with the engine code, the faster a breaker can confirm whether the part on their shelf is a genuine match for your car.
