Used Peugeot 3008 Lambda Sensor

Yes, but only on petrol-engined variants of the 3008 — lambda (oxygen) sensors are a standard part of the exhaust management system on petrol engines, typically sitting before and sometimes after the catalytic converter. Diesel 3008s (which make up a large proportion of those sold in the UK) do not use lambda sensors in the same way, as diesel exhaust management relies on different sensor types such as NOx sensors. Before ordering a used lambda sensor, confirm your 3008 has a petrol engine, as a diesel owner searching for this part is likely looking for something else entirely.

The first-generation 3008 ran from 2009 to 2016, and the second generation launched in 2016 — these are significantly different vehicles with different engines and exhaust layouts, so a lambda sensor from one generation will not reliably fit the other. The sensor connector type, thread pitch, and positioning in the exhaust system can all differ between the two generations. Stick to sourcing a sensor matched to your specific generation, and confirm the engine code with the breaker to be sure.

No — trim level does not affect lambda sensor fitment on the 3008; what matters is your engine code, fuel type, and the emissions standard applicable to your vehicle's year of registration. A sensor from a GT-spec 3008 petrol with the same engine code as your Active or Allure will be the same part. Just be aware that used sensors may come attached to sections of the original wiring loom that differ cosmetically, so confirm the connector and cable length with the breaker against your registration.

Both a 2013 and 2015 3008 fall within the first-generation model (2009–2016), so they are broadly the same platform, but fitment still depends on matching the engine code and emissions specification rather than the year alone. Euro 5 and emissions-related changes could mean subtle differences in sensor specification even within the same generation. Give your registration and engine code to the breaker and ask them to verify the part against their donor vehicle before you commit.

The first-generation 3008 received a facelift in 2013, but this was primarily cosmetic and did not introduce a wholesale change of engine family, so in many cases the lambda sensor specification remains the same across the pre- and post-facelift cars if the engine code matches. That said, some running changes to emissions equipment can occur around a facelift cycle, so the safest approach is to match by engine code rather than assuming year-to-year compatibility. Always confirm the engine code from your V5C or under the bonnet and pass it to the breaker before purchasing.

The 3008 HYBRID4, which paired a diesel engine with an electric motor, is diesel-based and diesel engines do not use conventional lambda (oxygen) sensors as part of their standard exhaust management — so this variant does not use the part in the same way as a petrol engine. If you are chasing an emissions-related sensor fault on a diesel or diesel-hybrid 3008, you are more likely looking for a NOx sensor or exhaust temperature sensor rather than a lambda sensor. Describe your exact fault code and registration to a breaker and they can advise which sensor you actually need.
