Peugeot 307 Sump Replacement Parts

The Peugeot 307 ran as a single generation from 2001 to 2008, with a facelift arriving in 2005, so a 2003 and a 2006 car sit either side of that facelift boundary. Fitment of a sump depends primarily on the engine code rather than the model year, so if both cars share the same engine code the sump is very likely compatible, but because ancillary and mounting details can change across a facelift you should confirm the match with the breaker using both registration numbers before buying.

For mechanical parts like a sump, the engine code is the single most important detail — far more reliable than the year or even the fuel type alone, because Peugeot fitted several different petrol and diesel engines to the 307 throughout its life and each has its own sump profile. You can find your engine code on your V5C or by running a VIN check. Always give the breaker your engine code alongside your registration so they can pull the right unit.

Trim level has no bearing on sump fitment whatsoever — the LX, S, SE, and other 307 trim grades all used the same engine families, and the sump is determined entirely by the engine fitted, not the badge on the tailgate. You may find cosmetic differences between cars (interior spec, alloy wheels and so on) but underneath the engine will be identical if the codes match. Confirm the engine code with the breaker and trim level need not enter the conversation.

The 307 HDi range included more than one diesel engine over its 2001–2008 production run, and different HDi units carry different engine codes, meaning the sumps are not necessarily interchangeable between variants. Quoting the breaker your exact engine code (not just 'HDi') is essential to ensure the sump pan, pick-up pipe position, and any sensor ports align correctly. Never assume all diesel 307 sumps are the same.

The 2005 facelift is a well-established production boundary for the 307, and while the engine codes themselves often carried across it, mounting points and ancillary details on the engine bay can differ between pre- and post-facelift builds. If your engine code matches exactly between the donor and your car, fitment is plausible, but you should confirm with the breaker against both registrations rather than rely on the facelift date alone. Giving the breaker both reg numbers lets them verify against the actual parts catalogues.

Petrol and diesel engines in the 307 are entirely different units with different sumps, so you must source a sump from a donor car with the same fuel type and matching engine code — a diesel sump will not fit a petrol engine. Stick to petrol donors and match on engine code first; year and fuel type together narrow the field, but the engine code is the definitive check. Ask the breaker to cross-reference your registration to make sure the part they have is a direct match.
