Cheap Hyundai i40 EGR Valve

Yes, but only on diesel variants — the i40 was sold in the UK with a 1.6 CRDi and a 1.7 CRDi diesel engine, and both of these use an EGR (Exhaust Gas Recirculation) valve as part of their emissions system. The petrol engine (a 1.6 GDi) does not use an EGR valve in the same way, so if your i40 is petrol you are unlikely to need this part. Always check your V5C or registration plate lookup to confirm your fuel type before ordering.

The Hyundai i40 ran from 2011 to 2019 as a single generation, with a facelift arriving in 2015 that brought some emissions and engine management updates — this 2015 boundary is the key point to flag when crossing years. Engine code is the critical match here: a 1.6 CRDi and a 1.7 CRDi use different EGR valves and should not be swapped. Even within the same engine code, confirm with the breaker that the part number is compatible across the pre- and post-facelift divide before buying.

No — trim level has no bearing on EGR valve fitment for the i40. The EGR valve is determined entirely by engine code (1.6 CRDi or 1.7 CRDi) and the emissions specification of the vehicle, not by whether it is an SE, Premium, or Style. Give the breaker your engine code and registration rather than your trim name and you will get the right match.

No — the 1.6 CRDi and 1.7 CRDi are different engines with different EGR valve assemblies, and they should not be treated as interchangeable. Always confirm the engine code on your car (visible on the V5C or via a registration lookup) and give that code directly to the breaker when requesting a quote. Fitting the wrong engine variant's EGR valve risks incorrect operation and potential emissions failures at MOT.

Yes — body style makes no difference to EGR valve fitment; the valve is part of the engine and emissions system, which is shared across both the estate (Wagon) and saloon body styles on the same engine code. What matters is matching the engine code and emissions specification, not the body shape. Confirm the engine code with the breaker and you can disregard whether the donor car was an estate or saloon.

A faulty EGR valve can certainly contribute to emissions failures, and a good used replacement from a breaker is a legitimate repair option — but the part must match your exact engine code and emissions era to ensure it performs correctly. On a post-facelift 2015–2019 i40 in particular, ensure the replacement meets the same Euro emissions standard as your vehicle, as fitting a part from an earlier spec car could leave you in the same position. A used EGR valve alone may not resolve the failure if there are other contributing faults, so have a mechanic diagnose the root cause before ordering.
