Cheap Peugeot 306 Sump

The 306 ran from 1993 to 2002 in a single generation, with a facelift in 1997 that updated the bodywork but did not change the fundamental engine lineup, so the key question is whether both cars share the same engine code rather than which side of 1997 they sit on. Sumps follow the engine, not the model year, so a pre-facelift and post-facelift 306 can share a sump if they have identical engine codes. That said, minor mounting or ancillary changes can occur mid-production even within the same engine family, so confirm the exact fit against your registration with the breaker before buying.

No — diesel and petrol engines are entirely different units with different sump designs, so a sump from a 1.9 diesel will not fit a 1.4 or 1.6 petrol, and vice versa. Always match on fuel type first, then pin down the exact engine code, which you can find on your V5 or through a VIN check. Supply the engine code to the breaker so they can pull the right part.

Trim level (XR, SR, XSi, and so on) does not affect sump fitment at all, because the sump is determined entirely by the engine code, not the badge on the back. A 306 XR and a 306 SR with the same engine code will use the same sump. Focus on confirming the engine code matches between donor and recipient car, and ignore the trim designation entirely.

The GTi-6 uses the high-revving 2.0 16v engine (engine code XU10J4RS), which is a different unit from the more common 1.8 and 2.0 8v petrols found in mainstream 306 models, so a sump from a standard 306 is very unlikely to be the correct fit. You should specifically source a sump from another GTi-6, or confirm the engine code match with the breaker before proceeding. Supplying your engine code directly to the breaker is the safest route given how specific this engine is.

The 1997 facelift updated the 306's exterior styling but did not introduce new engine families, so cars either side of that 1997 boundary can share a sump if the engine codes match. However, because ancillary or mounting details can change mid-production independent of a facelift, you should confirm the exact interchange against both registrations with the breaker rather than assuming the pre- and post-1997 parts are drop-in identical.

The single most useful thing you can supply is the engine code, which appears on your V5 logbook or can be retrieved via a VIN check — it tells the breaker far more than the year or trim level. Also confirm fuel type and gearbox type (manual or automatic), as these can influence which sump variant is needed. With those details in hand, a good breaker will be able to cross-reference their stock accurately and advise on fitment.
