Used Peugeot 106 Differential

The Peugeot 106 ran in two main generations: the Series 1 (1991–1996) and the Series 2 (1996–2004), with the Series 2 bringing a significant facelift and some mechanical revisions. Within the same generation, a differential is more likely to be compatible, but crossing the Series 1 to Series 2 boundary is where you need to be cautious — confirm with the breaker against your registration before buying, as subtle changes may affect fitment. The engine code is the single most reliable detail to supply, and you'll find it on your V5 or via a VIN check.

Yes, both matter — the differential in a manual-gearbox 106 is integrated into the gearbox casing, so the gearbox type and engine code together determine which unit you need. A petrol 1.0 or 1.1 (for example, those carrying a TU engine code) will require a different unit than a 1.4 or 1.6, and a diesel 106 (HDi or XUD-engined) will differ again. Always supply your engine code — found on your V5 or via a VIN check — when asking a breaker for a quote, as this is more reliable than quoting the badge or fuel type alone.

Trim level alone does not determine differential fitment — what matters is the engine code, and performance trims like the Rallye and GTi used higher-output engines with correspondingly different gearbox and differential specifications. A GTi or Rallye differential will not simply swap into a standard XR or XN without checking that the engine codes and gearbox ratios match. Be upfront with the breaker about your exact trim and engine code, as the performance models are mechanically distinct from the mainstream range.

The Series 2 facelift arrived during 1996, so a 1996 car could be either generation depending on when it was built and registered — this is exactly the kind of boundary case where you should confirm with the breaker against your registration number rather than assuming. The two generations can differ in gearbox and drivetrain specification, so getting this right matters for a mechanical part like the differential. A VIN check or your V5 registration document will help the breaker identify which series your vehicle is and source the correct unit.

No — diesel and petrol 106s use different engines and gearboxes, and the differential is part of the gearbox assembly, so the units are not directly interchangeable between fuel types. The petrol range covered various TU-series engine codes while the diesel used different units entirely, and the gearbox casings and ratios differ accordingly. Always tell the breaker your fuel type and engine code together to ensure you're quoted a compatible part.

Ask the breaker for the donor vehicle's mileage, engine code, and generation, and confirm these match your car — a differential from a matching engine-code car within the same generation gives you the best chance of a straight swap. It's also worth asking whether any mounting brackets or ancillary components differ from your original, as these can vary mid-production; confirm this with the breaker against your registration rather than assuming they're identical. A reputable breaker will be able to check the donor reg against yours and advise on any known fitment concerns.
