Second Hand Peugeot 107 Catalytic Converter

Yes, all petrol-engined Peugeot 107s were fitted with a catalytic converter as standard — the 107 was only ever sold in the UK with a 1.0-litre petrol engine, so every example on the road has one. There was never a diesel variant of the 107 sold in the UK, so there is no DPF to worry about on this model. If you are looking for an exhaust-related emissions component on a 107, a catalytic converter is the correct part.

The Peugeot 107 ran from 2005 to 2014, with a facelift arriving in 2012, and while the 1KR (1.0-litre) engine carried through much of the range, emissions calibration and exhaust system specifications can differ across that span. Crossing the pre-facelift to post-facelift boundary — particularly around Euro 4 to Euro 5 compliance — means a cat from the earlier car may not meet the emissions standard required for your MOT, even if it physically bolts on. Always confirm the engine code and emissions standard of the donor vehicle against your own registration with the breaker before purchasing.

No — on the Peugeot 107, trim level does not affect catalytic converter fitment at all. Access, Envy, Urban, Millesim and other UK trim grades all used the same 1.0-litre petrol engine and shared the same exhaust system layout, so the cat is determined by engine code and model year rather than trim. You may find minor cosmetic differences in surrounding heat shields or bracketry depending on the specific car, but the core catalytic converter unit is unaffected by trim level.

The Peugeot 107, Toyota Aygo, and Citroën C1 were all built on the same platform and share the 1KR 1.0-litre petrol engine, which means there is a reasonable chance of parts interchangeability. However, exhaust system routing and exact cat specifications can vary between the three brands even on the same underlying engine, and emissions-era differences add another variable. Confirm with the breaker that the donor vehicle's engine code, build year, and emissions standard match your own 107's registration before agreeing a purchase.

The key factors are that the replacement cat must match your car's engine code and meet the emissions standard — Euro 4 for pre-facelift 107s and Euro 5 for post-facelift (2012 onwards) — because fitting a cat from an earlier emissions era can cause your car to fail the MOT exhaust emissions test. A physically fitting cat from a mismatched year may not be calibrated correctly for your car's engine management system. Confirm the donor vehicle's registration, engine code, and emissions compliance with the breaker before buying.

Both a 2007 and 2008 Peugeot 107 fall within the pre-facelift generation (2005–2011) and should share the same 1KR 1.0-litre engine specification, making a same-era replacement a realistic prospect. That said, catalytic converter interchange specifics are strong confirm-with-breaker territory — ask the breaker to check the engine code and emissions standard of the donor car against your registration to be sure. Never rely on year alone as the sole guide to fitment.
