Second Hand Peugeot 107 Alternator

The Peugeot 107 was sold as a single generation running from 2005 to 2014, with a facelift in 2009, so a 2008 unit sits in the pre-facelift period and a 2012 unit is post-facelift. The alternator follows the engine code rather than the model year, so if both cars share the same engine code the unit will very likely be compatible, but because ancillary and mounting details can change across the 2009 facelift boundary you should confirm fitment with the breaker against your exact registration before buying.

The engine code is the single most important detail for alternator fitment — far more reliable than the year alone. Two 107s from the same year could carry different engines and require different alternators, so check your V5 logbook or run a VIN check to find your engine code and always quote it to the breaker.

Yes, fuel type matters because the engine architecture is completely different between petrol and diesel variants, and the alternators are not interchangeable between them. Always confirm to the breaker whether your car is petrol or diesel alongside the engine code, as this will immediately rule out a large number of unsuitable donor vehicles.

Trim level does not affect alternator fitment on the 107 — Access, Urban, and Platinum are purely cosmetic and equipment-level differences and have no bearing on the engine or its ancillaries. The alternator is determined by the engine code, so a unit from any trim will suit yours provided the engine codes match; just be aware you may receive a part with minor cosmetic differences in bracket finish or labelling that make no functional difference.

The Peugeot 107, Toyota Aygo, and Citroën C1 were built together as the PSA–Toyota city-car project and share the same platform and engines, so alternators from the equivalent engine code across all three are widely regarded in the trade as interchangeable. However, because ancillary fitment details and any mid-production changes can vary, you should confirm with the breaker that the specific unit they have is confirmed to suit your registration before purchasing.

The 107 facelift occurred in 2009, meaning a 2006 car is pre-facelift and a 2011 car is post-facelift, and while the engine codes often remained the same across that boundary the alternator and its mounting can differ due to ancillary changes made during the refresh. Name your engine code to the breaker and ask them to check the specific unit against your registration, as this is the only reliable way to confirm cross-boundary fitment.
