Cheap Mercedes-Benz SLK Dual Mass Flywheel

Yes, but only on diesel and manual-gearbox petrol variants — the SLK was offered with diesel engines (notably the 250 CDI) and some manual petrol options that use a dual mass flywheel (DMF) to absorb drivetrain vibration. However, the majority of SLKs sold in the UK were petrol automatics with a torque converter, which do not use a DMF at all. If your SLK is an automatic, you are almost certainly looking for a torque converter rather than a flywheel. Check your gearbox type and engine code before searching.

The DMF is associated with manual-gearbox applications, most notably the diesel R172 250 CDI (engine code OM651) and certain manual petrol variants across the generations. Because Mercedes ran mid-production engineering changes, the engine code from your V5 or a VIN check is the single most reliable detail to give a breaker — the badge alone (200, 250, 350) does not confirm whether a DMF is fitted. Confirm the exact code with the breaker against your registration before ordering.

The R171 and R172 are distinct generations with different engine families, so a DMF from an R171 is very unlikely to be a straight swap into an R172 even if the engine capacity looks similar on paper. The R172 250 CDI uses the OM651 unit, which has its own specific flywheel specification. Always quote your exact engine code to the breaker and ask them to check it against the donor vehicle's code — never assume a cross-generation transfer will work.

Trim and badge level do not affect flywheel fitment — what matters is the engine code, fuel type, and gearbox type, not what the boot lid says. Two cars both badged SLK 250 could have different specifications depending on build date, so the badge is a starting point at best. Give the breaker your full engine code (found on the V5 or via a VIN check) and confirm your gearbox type, and they can match the correct part regardless of trim designation.

The R172 ran from 2011 to 2016 with a facelift around 2016, so a 2013 car sits within the pre-facelift R172 production run. Minor ancillary or mounting changes can occur across a production run without a formal facelift, so it is worth confirming with the breaker that the donor vehicle's build date and engine code match yours closely. Quote your registration to the breaker so they can cross-reference the exact flywheel specification rather than relying on model year alone.

The SLK 250 CDI shares its OM651 engine family with several other Mercedes models, so there is a realistic chance of cross-model compatibility on paper — but bell housing depth, starter ring tooth count, and transmission bolt patterns can differ between applications. This is a case where you must confirm compatibility with the breaker against both the donor and recipient registration numbers before purchasing. Do not assume engine code alone is sufficient when crossing model lines.
