Used Peugeot 408 Flywheel

It depends on the variant: 408s fitted with a manual gearbox have a conventional solid flywheel, while those fitted with an automatic gearbox use a torque converter and flexplate instead of a traditional flywheel. If you have a manual 408, a flywheel is the correct part to search for; if you have an automatic, you need a flexplate or torque converter rather than a flywheel. Check your V5 or a VIN check to confirm your gearbox type before ordering.

The Peugeot 408 ran in its first generation from around 2010 to 2014, with the second generation arriving from 2014 onwards, so a 2013 and a 2016 car sit in different generations and may use different engine configurations. The engine code is the key detail here — if both cars share the same engine code (visible on your V5 or a VIN check), there is a stronger chance of compatibility, but crossing a generational boundary like this means you should confirm interchangeability with the breaker against both registrations before buying.

Trim level makes no difference to flywheel fitment — Active, Allure, and GT Line are specification packages that affect the interior, equipment, and cosmetics, not the engine or drivetrain. What matters is the engine code, fuel type (petrol or diesel), and gearbox type (manual), all of which can vary independently of trim. Give the breaker your engine code and registration and they can match the correct flywheel regardless of which trim your 408 is.

Yes, fuel type matters significantly — petrol and diesel engines operate at different torques and RPM characteristics, so their flywheels are engineered differently and are not interchangeable. Even within petrol or diesel, different engine codes can mean different flywheel specifications, so the engine code (found on your V5 or via a VIN check) is more reliable than fuel type alone. Always give the breaker your full engine code to ensure the correct unit is supplied.

Peugeot models that share the same engine code sometimes use the same flywheel, since the flywheel is matched to the engine and bellhousing rather than the car body — this is the principle that makes cross-model sourcing potentially viable. However, gearbox mounting and bellhousing dimensions can differ between models even with a shared engine code, so this is not something to assume without checking. Confirm compatibility with the breaker by supplying the engine codes from both donor and recipient vehicles before purchasing.

Many Peugeot 408 diesel variants, particularly those with the 2.0 HDi engine, were originally fitted with a dual-mass flywheel (DMF) from the factory, while some petrol variants may use a solid flywheel — but this can vary by engine code and production date. Fitting a solid flywheel conversion in place of a DMF is possible but typically requires a matching clutch kit and should be discussed with a mechanic before proceeding. Give the breaker your engine code and registration so they can confirm whether the unit they have is a DMF or solid flywheel and whether it matches your original specification.
