Second Hand Peugeot 407 Differential

The Peugeot 407 ran as a single generation from 2004 to 2011, with a facelift arriving in 2008, so there is a mid-production boundary to be aware of. Engine code is the most important factor — a differential from a same-engine-code 407 is your strongest starting point, and fuel type and gearbox type (manual or automatic) must also match. Whether the differential crosses the pre-facelift to post-facelift 2008 boundary without any mounting or ancillary changes is something you should confirm with the breaker against your registration, as small production updates can affect direct swap compatibility. Never assume fitment without checking.

A 2006 407 is pre-facelift and a 2009 is post-facelift, so you are crossing the 2008 production boundary, which is the key consideration here. Providing your engine code — found on your V5 or via a VIN check — gives a breaker the best chance of identifying a compatible unit, alongside confirming your gearbox type. Fitment across that facelift boundary should be confirmed with the breaker against your registration rather than assumed. Engine code, fuel type, and gearbox type are the details to have ready.

Trim level — whether your 407 is an SE, Executive, SR, or GT — does not affect which differential you need; the mechanical specification is determined by engine code, fuel type, and gearbox type, not the badge on the boot. A differential from an SE-spec 407 with the same engine code and gearbox type as a GT-spec car is mechanically the same unit. You may find cosmetic differences in how surrounding components look on a stripped car from the breaker, but these have no bearing on the differential itself. Focus on engine code and gearbox type when requesting quotes.

No — petrol and diesel variants of the 407 can have different differentials to suit the different torque outputs and drivetrains involved, so fuel type is an important filter when sourcing this part. Always specify whether your car is petrol or diesel when contacting a breaker, alongside your engine code. The engine code is the single most reliable detail because it defines the exact specification your differential must match. Do not assume a diesel unit will suit a petrol car or vice versa.

Yes, gearbox type matters — a 407 fitted with an automatic gearbox will have a different final drive arrangement compared with a manual gearbox car, so you must specify which you have when requesting quotes. Confirm whether your car is manual or automatic before approaching a breaker, and have your engine code to hand as well. Supplying your registration to the breaker allows them to verify the exact specification required. Mixing gearbox types is not a straightforward swap and should not be attempted without expert advice.

The 407 was offered as a saloon, estate (SW), and Coupe, and while the Coupe shares the same basic platform, whether its differential is a straight swap onto a saloon or SW should be confirmed with the breaker against your registration. Engine code, fuel type, and gearbox type remain the primary fitment factors regardless of body style. Body style itself does not automatically determine compatibility, but ancillary or mounting differences between variants are possible and the breaker is best placed to verify this. Have your engine code and gearbox type ready when you make contact.
