Nissan Micra EGR Valve Replacement Parts

Yes, but only on diesel-engined Micras — the 1.5 dCi variants used across the K12 (2003–2010) and K13 (2010–2017) generations are fitted with an EGR valve as part of their emissions control system. Petrol Micras — which make up the vast majority sold in the UK — do not have an EGR valve at all, so if your Micra is a petrol you will not find this part on the car. If you are unsure which engine you have, check your V5C or the engine code on the cam cover before ordering.

Both years fall within the K12 generation (2003–2010) and share the 1.5 dCi engine, so there is a reasonable chance of compatibility, but you should confirm the exact engine code with the breaker against your registration before buying. The K12 received a facelift in 2007 which did not change the engine itself, but emissions calibration updates across that period mean a like-for-like engine code match is the safest approach. Never assume fit on emissions-related parts without that check.

The K12 (2003–2010) and K13 (2010–2017) generations both used 1.5 dCi engines, but the K13 moved to stricter Euro 5 emissions standards, which typically brought changes to EGR system design and calibration. Fitting a part from the wrong emissions era risks both a poor mechanical fit and a potential MOT emissions failure, so this is a firm 'confirm with the breaker' situation — give them your registration and ask them to match engine code and emissions standard. Do not assume the parts are interchangeable simply because the engine displacement is the same.

No — on the Nissan Micra, trim level has no bearing on EGR valve fitment. The Visia, Acenta, and Tekna trims all share the same engine options, so what matters is the engine code and emissions specification, not the badge on the back. Just match the engine code from your registration and the breaker can source accordingly.

Yes, it matters significantly — EGR valves are emissions-critical components and a unit from the wrong engine code or emissions era can cause your car to fail again even if it physically fits. For the dCi Micra, make sure any used part is matched to your exact engine code and that the donor car sat within the same Euro emissions band as yours. Always tell the breaker your full registration so they can cross-reference these details before supplying the part.

The key details to give the breaker are your registration number, your engine code (usually found on a sticker on the engine or in your service documents), and your fuel type — diesel only in this case. A reputable breaker will check these against their donor vehicle before supplying the part, which is the most reliable way to avoid a mis-match on an emissions-related component. Do not rely on year alone, as running changes across a production run can affect compatibility even within the same generation.
