Used Nissan Navara EGR Valve

Yes, all diesel Navara variants sold in the UK are fitted with an EGR (exhaust gas recirculation) valve as part of their emissions control system. The Navara has been sold in the UK exclusively with diesel engines, so every example you are likely to encounter will have one. If your Navara is throwing an EGR-related fault code or suffering poor running, a used EGR valve is a legitimate repair option.

These are two distinct generations with different engine families — the D40 used the 2.5 dCi (YD25DDTi engine code) while the D23 uses the 2.3 dCi (YS23DDT engine codes), so the EGR valves are not interchangeable between them. Always confirm the engine code on your V5C or with your breaker before purchasing, as the external appearance of the valve can be deceptively similar. Do not assume a D40 unit will drop straight onto a D23 or vice versa.

Trim level makes no difference to EGR valve fitment on the Navara; what matters is the engine code and the emissions standard (Euro 5 or Euro 6) the vehicle was built to, not whether it is a Visia, Acenta, Tekna or Trek. All UK D23 Navaras share the same 2.3 dCi engine family regardless of trim, so a valve pulled from a Tekna breaker car is mechanically the same as one from a Visia. You may find minor ancillary differences in wiring connectors or brackets depending on the specific build, so have your registration to hand when speaking to the breaker.

The D40 generation ran from 2005 to 2015 with a facelift around 2010, and while the core 2.5 dCi YD25DDTi engine carried through much of this period, emissions calibration and associated EGR componentry can differ across the pre- and post-facelift cars. A valve from the same engine code and emissions era is your best starting point, but crossing the 2010 facelift boundary is where you should confirm directly with the breaker that the part number and connector type match your specific registration. Do not assume all D40 EGR valves are identical simply because the engine designation looks the same.

Yes, emissions era is one of the most important factors for EGR fitment because the valve is a core part of the emissions management system and its specification is matched to the engine tune and associated hardware for that standard. On the D23 Navara, Euro 6 variants introduced stricter emissions hardware, and a valve from a Euro 5 car may not function correctly or could cause an MOT failure if fitted to a Euro 6 vehicle. Check your V5C or the DVLA vehicle enquiry service to confirm your vehicle's emissions standard, and relay that information to the breaker before agreeing a purchase.

Beyond matching the engine code and emissions era, ask the breaker to confirm the part number from the donor vehicle and check that the electrical connector and any vacuum or coolant ports match your existing unit. The EGR valve on the Navara works closely with the DPF and associated pipework, so if your breaker is also supplying related exhaust components, confirm compatibility for those parts individually against your registration rather than assuming they are interchangeable as a set. A reputable breaker will be able to cross-reference your registration to the donor vehicle before dispatch.
