BMW 1 Series Dual Mass Flywheel Replacement Parts

Yes, but only on manual gearbox variants — the dual mass flywheel (DMF) sits between the engine and the clutch on manual transmission models and is not present on automatic or DCT-equipped cars. It exists across diesel and petrol manual variants of the 1 Series, so you first need to confirm you have a manual gearbox before searching. If you have an automatic or DCT gearbox, there is no DMF to replace and what you may actually need is a torque converter instead.

The E87 (2004–2011 five-door hatchback), E82 (coupé) and E88 (convertible) all share the same basic platform and in many cases the same engine families, so the DMF fitment is driven by the engine code rather than the body style — body style does not affect which flywheel you need. If both cars share the same engine code, there is a strong chance of compatibility, but you should confirm the specific part number with the breaker against both registrations before buying. Never assume body style alone determines fitment.

The F20 (2011–2019) and E87 (2004–2011) are entirely different generations with different engine families, so a DMF from an E87 is very unlikely to fit an F20. The F20 used revised engine codes such as the N13, N20, and B47 family diesels, which differ fundamentally from the older N45, N46, and M47 units found in the E87. Always quote your engine code to the breaker rather than just the year, as this is the detail that determines which flywheel fits.

No — SE, Sport, and M Sport are trim levels that affect cosmetics, upholstery, and suspension tuning, but they do not change the engine or gearbox type in a way that affects the DMF itself. The flywheel is determined entirely by your engine code and the fact that you have a manual gearbox, both of which you can find on your V5 or via a VIN check. Tell the breaker your engine code and confirm manual transmission and they will be able to match the correct part regardless of trim.

The F20 received a facelift in 2015, and while some engine codes carried over, others were updated or replaced — for example, the B47 diesel and B38/B48 petrol units were introduced or revised around this period. Because of this, a 2015 facelift car and a 2012 pre-facelift car may or may not share the same DMF even if the badge on the boot lid looks identical. Quote your exact engine code to the breaker and ask them to confirm fitment against your registration, as mid-production changes can affect ancillary components even within the same generation.

Fuel type matters — diesel and petrol engines produce very different torque characteristics and the DMF is specifically engineered for each engine, so a diesel flywheel will not be interchangeable with a petrol one even if the cars look similar externally. The engine code is the most reliable guide here, and a diesel engine code and petrol engine code will be distinct even within the same generation. Always give the breaker your full engine code and confirm the donor car's fuel type matches yours before agreeing a price.
