Peugeot 108 EGR Valve Replacement Parts

The Peugeot 108 (2014–2021) was sold exclusively with small petrol engines — the 1.0 VTi (1KR-FE) and the 1.2 VTi (HMZ) — and none of these variants were fitted with an EGR valve as standard. EGR valves are primarily associated with diesel engines, where recirculating exhaust gas helps control NOx emissions, and the 108 never had a diesel option in the UK. If your dashboard warning light or a diagnostic code has led you to search for an EGR valve, it is worth double-checking the fault code with a mechanic, as the issue may relate to a different emissions or intake component.

It is extremely unlikely — EGR systems are integrated into the engine management and exhaust architecture at the factory design stage, and retro-fitting one to a naturally aspirated petrol engine like those in the 108 would serve no practical purpose and is not a known modification. If a diagnostic tool is flagging an EGR-related code on your 108, this is more likely a sensor, wiring, or software fault elsewhere in the emissions system rather than a missing or failed EGR valve. A Peugeot specialist or independent garage with the correct diagnostic equipment will be best placed to interpret the fault accurately.

The 108's petrol engines do have a catalytic converter as part of the exhaust system, and this is the main emissions-control component you are likely to need if you are chasing an emissions or engine management fault. Some later Euro 6 compliant 108s (from around 2015 onward) may also have additional catalyst or sensor configurations — confirm the exact setup with a breaker against your registration, as interchange specifics across the model's emissions eras are strong confirm-with-breaker territory. The oxygen (lambda) sensors before and after the catalytic converter are another component that can trigger emissions-related fault codes and are worth investigating.

Yes, it can matter — the 108 received a facelift in 2018 which brought minor updates, and emissions regulations tightened across the model's life, meaning exhaust and catalyst specifications could differ between earlier Euro 5-era cars and later Euro 6 models. Always give a breaker your full registration number so they can verify the exact engine code and emissions specification before supplying any part. A visually similar component from the wrong emissions era may not fit correctly or could cause an MOT failure.

No — trim level does not affect the emissions or exhaust system specification on the Peugeot 108; an Active, Allure, and GT Line on the same engine code and the same model year will share the same catalytic converter and exhaust components. What matters for sourcing used parts is the engine code and the emissions standard (Euro 5 or Euro 6) tied to the car's year of registration, not whether the car has extra trim or a different interior specification. Always confirm against your registration with the breaker regardless of trim.
