Peugeot 306 Differential Replacement Parts

The engine code is the single most important detail — it determines which differential was fitted far more reliably than the year or badge alone. You'll find the engine code on your V5C or via a VIN check, and supplying it to the breaker will save a lot of back-and-forth. Also tell them your fuel type, gearbox type (manual or automatic), and the year of your car to help them narrow it down further.

The 306 ran from 1993 to 2002 as a single generation, with a significant facelift in 1997 that updated the bodywork and some mechanical components. Whether a differential from a pre-1997 car crosses over to a post-1997 car — or vice versa — depends on the engine code, so if your search spans that 1997 boundary you should confirm interchangeability with the breaker against your exact registration rather than assuming a straight swap.

Because the 1997 facelift is a meaningful production boundary, parts from a 1995 car and a 1999 car don't automatically interchange without checking. Match the engine codes on both vehicles first — if they share the same code and gearbox type, fitment is much more likely, but you should still confirm with the breaker against your registration as ancillary or mounting details can differ across that boundary.

Trim level itself does not affect which differential was fitted — what matters is the engine code, fuel type, and gearbox type, all of which can vary across those trim grades. An SR and an XSi with the same engine code and gearbox are far more likely to share a differential than two cars with different engine codes wearing the same badge. When you contact a breaker, lead with the engine code rather than the trim name and you'll get a more reliable answer.

No — diesel and petrol variants of the 306 used different drivetrains, and the differentials are not interchangeable between fuel types. Always confirm your fuel type alongside the engine code when requesting a quote, as a breaker needs both details to pull the correct unit. Mixing fuel types when sourcing a mechanical drivetrain part is one of the most common fitment mistakes on cars like the 306.

Some Peugeot and Citroën models from the same era shared drivetrains, so there may be cross-platform compatibility in certain cases — but this is entirely dependent on the engine code, gearbox type, and specific ratios involved. Do not assume a differential from another model will fit without checking, as even closely related platforms can differ in final drive ratio or mounting points. Put the question to the breaker with your full engine code and registration, and they can advise whether a donor from a different model is worth considering.
