Second Hand Hyundai i20 Dual Mass Flywheel

Only some i20 variants were fitted with a dual mass flywheel — it is found on diesel-engined models and certain turbocharged petrol variants, but naturally aspirated petrol i20s typically use a conventional single mass flywheel instead. If you are unsure which type your car has, check your engine code on your V5 or via a VIN check and confirm with the breaker, as fitting the wrong type will cause serious drivability problems. Do not assume your car has one without verifying the engine code first.

These are entirely different generations with different engine families, so a flywheel from the first-generation i20 (2008–2014) will not reliably interchange with a second-generation i20 (2014 onwards) even if the engine displacement looks similar on paper. The engine code is the critical matching point — supply your engine code to the breaker so they can confirm whether a specific unit is compatible rather than going by year alone. Crossing a generation boundary like this should always be confirmed with the breaker against your registration.

Both years fall within the second-generation i20 (2014–2020), so they share the same broad engine family, but there can be running production changes to ancillary components and mounting details mid-generation that are not always publicly documented. The safest approach is to give the breaker your full engine code alongside your registration so they can match the correct unit rather than relying on year alone. Year is a useful guide, but engine code is what the breaker will use to confirm fitment.

Trim level does not affect dual mass flywheel fitment — the flywheel is determined by the engine and gearbox, not the badge or equipment level. An SE and a Sport i20 with identical engine codes and manual gearboxes will use the same flywheel. What may differ between trims is unrelated equipment such as alloy wheels or interior finish, so do not be put off by cosmetic differences when sourcing from a breaker.

No — diesel and petrol flywheels are engineered to different specifications and are not interchangeable, even where the physical dimensions look similar. Diesel engines produce significantly different torque characteristics that the dual mass flywheel is tuned to absorb, so fitting a diesel unit to a petrol engine (or vice versa) is not appropriate. Always confirm fuel type and engine code with the breaker when sourcing this part.

Conversion kits do exist that replace a dual mass flywheel with a single mass unit and an uprated clutch, and some owners choose this route as a cost-saving measure on higher-mileage vehicles. However, this is a modification that affects NVH (noise, vibration, and harshness) and may not be appropriate for all uses, so it is worth discussing with your mechanic before deciding. A good breaker can supply either a genuine used dual mass unit or advise on whether a conversion kit is available for your specific engine code.
