Used Mercedes-Benz CLA Dual Mass Flywheel

Yes, the CLA does use a dual mass flywheel (DMF), but only on diesel and manual or dual-clutch automatic (DCT) petrol variants — it is not fitted to every engine in the range. Diesel models such as those using the OM651 and later four-cylinder diesel units are the most common application, as DMFs are standard on high-torque diesel drivetrains. If you have an automatic petrol CLA with a conventional torque-converter gearbox, a separate DMF is not part of the drivetrain in the same way, so confirm with a breaker against your registration before ordering.

The C117 (2013–2019) and C118 (2019–present) are distinct generations with different engine families and mounting arrangements, so a DMF from a C117 is very unlikely to cross over to a C118. The most reliable way to confirm compatibility is to supply both the engine code (found on your V5 or via a VIN check) and your registration to the breaker, who can verify part numbers directly. Never assume generation-to-generation interchange without that check.

Engine code is the single most important detail — two C117s built in the same year can have different DMFs if they carry different engine codes. The C117 received a facelift in 2016, and while the core engine codes largely carried over, there can be ancillary or mounting differences mid-production that affect which DMF fits correctly. Give the breaker your engine code alongside your registration rather than year alone, and let them cross-reference part numbers to be sure.

Trim level — whether that is SE, AMG Line, Sport, or Night Edition — does not affect which dual mass flywheel is fitted; it is the engine code and gearbox type that determine the correct unit. A CLA 220 d AMG Line and a CLA 220 d SE with the same engine code and gearbox will take the same DMF. What can differ between trim levels is cosmetic detail on other components, but for a mechanical part like the DMF you can disregard badge and trim entirely.

The CLA 200 d uses a four-cylinder diesel engine and in most configurations is paired with a DMF as standard, so yes, it is very likely to have one. However, gearbox type can influence the exact specification of the DMF, so confirm your engine code (visible on the V5 or via a VIN decoder) with the breaker before they source a unit. Supplying your registration directly to the breaker is the quickest route to getting the right part matched.

Where the engine code is genuinely identical and the gearbox type matches, there is a reasonable chance of compatibility between the CLA and other models in the same Mercedes family — the DMF follows the drivetrain, not the body. However, ancillary or mounting variations can exist even between shared-platform vehicles, so this is not something to assume without a part-number check. Put the engine code, gearbox type, and both registrations to the breaker and ask them to verify before committing.
