Second Hand Hyundai Kona EGR Valve

It depends entirely on which engine your Kona has. EGR valves are fitted to diesel and some petrol turbocharged engines to recirculate exhaust gases and reduce NOx emissions — the Kona's 1.6 CRDi diesel engine does have an EGR valve, as does the 1.0 T-GDi and 1.6 T-GDi petrol engines to varying degrees depending on the emissions standard. If your Kona is a first-generation model (2017 onwards) with a diesel engine, sourcing an EGR valve is straightforward; if you're unsure which engine you have, check your V5C or the sticker under the bonnet for the engine code before searching.

The Hyundai Kona ran as a first generation from 2017 to 2023, with a facelift arriving around 2021, so a 2018 and a 2022 car sit either side of that facelift boundary. Although the engine codes themselves — such as the 1.6 CRDi diesel — carried across into the facelifted model, emissions calibration and associated components can differ between pre-facelift and post-facelift variants, and a part that looks identical may not be mapped correctly for your car. Name the engine code from your V5C when speaking to the breaker and ask them to confirm the part number against your specific registration rather than just the year.

No — trim level has no bearing on EGR valve fitment for the Hyundai Kona. Whether your car is an SE, SE Connect, Premium, or Ultimate, what matters is the engine code and the emissions standard the car was built to, not the specification level. Tell the breaker your engine code (for example D4FB for the 1.6 CRDi diesel) and your registration, and trim is irrelevant to the search.

No — diesel and petrol EGR valves are entirely different components designed around very different exhaust temperatures, gas volumes, and engine management systems. The 1.6 CRDi diesel unit will not interchange with the 1.0 T-GDi or 1.6 T-GDi petrol units even if they look superficially similar. Always match the part to the exact engine code on your V5C.

The 48V mild-hybrid versions of the Kona — introduced during the first generation's later years — use the same underlying combustion engines as their non-hybrid counterparts, so the EGR valve itself is still present and is engine-specific rather than hybrid-system-specific. However, the mild-hybrid system does add components in close proximity, so confirm with the breaker that the donor car is also a 48V mild-hybrid with the same engine code to be sure nothing else in the assembly differs.

This is an important distinction — Euro 5 and Euro 6 engines are calibrated to different emissions thresholds, and EGR systems play a direct role in meeting those targets. Fitting a Euro 5 EGR valve to a Euro 6 engine could cause the engine management system to flag faults, affect emissions output, and potentially cause an MOT failure. Always confirm the emissions standard of the donor vehicle with the breaker against your own registration before purchasing.
