Peugeot 108 Lambda Sensor Replacement Parts

Yes, but only on petrol-engined 108s — the 1.0 VVT three-cylinder and the 1.2 VTi variants both use an oxygen (lambda) sensor as part of their exhaust and engine management systems. The 108 was never offered with a diesel engine in the UK, so every 108 on the road is petrol and will have at least one lambda sensor. If you are unsure whether your car has a pre-cat or post-cat sensor (or both), check with a breaker quoting against your exact registration.

The Peugeot 108 ran from 2014 to 2022 with a facelift arriving in 2018 — what matters for lambda sensor compatibility is the engine code rather than the model year alone, and the 1.0 VVT engine carried across both pre- and post-facelift cars. That said, whether the sensor connector, thread pitch, and calibration are identical across the 2018 facelift boundary is worth confirming with the breaker against your registration before buying. Engine code matching is the safest starting point.

No — trim level makes no difference to which lambda sensor you need on the Peugeot 108; Active, Allure, and Collection trims all share the same exhaust and engine management setup for a given engine. What matters is the engine code and the emissions standard (Euro 5 or Euro 6) that applies to your car's year of registration. Trim only affects cosmetic items, not the exhaust or sensor specification.

Yes, engine code is the most important thing to match — the 108 was available with a 1.0-litre (engine code 1KR) and a 1.2-litre (engine code HMZ), and their exhaust systems and sensor specifications differ. Always give the breaker your engine code, which you can find on the V5C or stamped on the engine, alongside your registration. Do not assume that any 108 sensor will fit simply because the cars look the same.

Euro 5 and Euro 6 emissions legislation can affect sensor specification, wiring, and calibration, so a sensor from an earlier Euro 5 108 may not be a straightforward swap into a Euro 6 car even if it looks identical. The Euro 6 requirement came into force for new passenger cars registered from September 2015, so use your registration date as a guide to which standard your car was built to. Confirm the emissions era of the donor car with the breaker against your registration before purchasing.

The 108, C1, and Aygo are all built on the same platform and share the same engines, so there is a reasonable chance the lambda sensor is shared across all three — particularly on the 1.0 VVT (1KR engine). However, connector type, sensor length, and calibration can vary by production date and emissions standard, so this is something to confirm with the breaker rather than assume. Give the breaker both registrations and ask them to cross-reference before committing.
