Second Hand Peugeot 406 Flywheel

The 406 was available with both manual and automatic gearboxes, and a traditional flywheel is specific to the manual gearbox variants — automatic versions use a torque converter and driveplate instead, not a flywheel. So if your 406 has a manual gearbox, yes, it has a flywheel; if it has an automatic, you need a driveplate rather than a flywheel. Make sure you know your gearbox type before searching, as these are completely different parts.

The Peugeot 406 ran as a single generation from 1995 to 2004, with a facelift in 1999 that was primarily cosmetic, so there is no full model-generation break to worry about. Flywheel fitment is driven by the engine code above anything else, so a flywheel from a 1997 car and one from a 2002 car could well be compatible if the engine codes match — but whether a specific flywheel crosses the 1999 facelift boundary should be confirmed with the breaker against your registration. Always quote your engine code, which you can find on your V5 or via a VIN check, when requesting a quote.

Trim level makes no difference to flywheel fitment whatsoever — the flywheel follows the engine and gearbox, not the badge or trim specification. An LX and an Executive with the same engine code and manual gearbox use the same flywheel. What you do need to match is the engine code and confirm it is a manual gearbox car, regardless of trim.

No, a petrol flywheel will not be a straight swap for an HDi diesel unit — diesel engines typically run at higher compression and torque loads, and the flywheel specifications including weight and dimensions are matched to the specific engine. The engine code is the critical detail here; the HDi engine family has its own flywheel, distinct from the petrol units. Always quote your exact engine code to the breaker to ensure a correct match.

Body style has no bearing on flywheel fitment at all; the flywheel is matched to the engine and gearbox assembly, which is the same regardless of whether the car is a saloon, estate, or coupe. Give the breaker your engine code and confirm you have a manual gearbox, and the body style can be ignored entirely for this part.

Whether your 406 diesel was originally fitted with a single-mass or dual-mass flywheel depends on the specific engine code and production details, and mixing the two types is not a straightforward swap as the clutch components are designed to match the flywheel type. This is something you should confirm with the breaker against your exact registration and engine code, as getting it wrong can lead to clutch and gearbox problems. A good breaker will be able to identify the correct type from your registration before supplying the part.
