Second Hand Peugeot 107 Engine

The Peugeot 107 was sold as a single generation from 2005 to 2014, with a facelift in 2012, so all 107s share the same basic platform throughout that run. Fitment depends primarily on the engine code rather than the year alone — a petrol 107 used the 1KR engine code (1.0 three-cylinder) and the diesel used the 1ND engine code (1.4 HDi), and you need to match that code exactly. Cross-checking the engine code from your V5 or a VIN check before buying is the single most useful step you can take, as ancillary and mounting changes may have occurred across the 2012 facelift boundary — confirm that detail with the breaker against your registration.

The 107 facelift arrived in 2012, and while the engine codes themselves carried over, whether a pre-facelift engine drops straight into a post-facelift car without modification — particularly regarding ancillaries, mounts, and engine management — is something you should confirm with the breaker against your specific registration. The engine code on both cars must match, and stating the donor car's year and your car's year clearly to the breaker will help them advise you accurately. Never assume a cross-facelift swap is straightforward without that check.

For the 1.0 petrol 107, trim levels like Access, Envy, and Sport did not use different engines — they all shared the same 1KR engine code, so trim is not a meaningful fitment factor for the engine itself. You may find minor cosmetic or ancillary differences between donor cars depending on spec, but the core engine is the same unit across those trims. Focus on matching the engine code, fuel type, and gearbox type (manual or automated manual) rather than the trim name of the donor vehicle.

Yes — the 107 was offered with a conventional manual gearbox and also with an automated manual transmission (marketed as the 2-Tronic), and while the engine code may be the same, the engine and its ancillaries can be set up differently depending on which transmission it was paired with. When sourcing a used engine, always tell the breaker which gearbox type your car has so they can supply the correct unit or advise on any differences. Confirm with the breaker against your registration whether any management or sensor differences apply between manual and 2-Tronic variants.

The Peugeot 107, Toyota Aygo, and Citroën C1 were all built on the same platform and share the same engine family — the 1.0 petrol unit carries the 1KR engine code across all three, so a donor engine from either of those models is worth asking about. In practice, breakers regularly supply engines from any of the three cars for any of the others, but you should confirm with the breaker that the engine code, gearbox type, and any ancillary configuration match your specific car. Immobiliser and ECU pairing questions are something to raise directly with the breaker or a specialist, as we cannot confirm coding requirements as fact.

The 1.0 petrol 107 uses the 1KR engine code and the 1.4 diesel uses the 1ND engine code — quoting the correct code to the breaker is far more useful than giving the year or trim alone. You can find the engine code on your V5 logbook or by running a VIN check, and having it to hand means the breaker can locate a confirmed matching unit quickly. Always give the breaker your registration number as well so they can verify the full specification against their stock.
