Mercedes SLC200 Timing Chain Wear (M274)
If your SLC200 has the M274 4-cylinder petrol engine — which is the only engine used in the SLC200 across its full 2016–2020 production run — timing chain wear is an established pattern on this engine family, shared with the wider M270/M274 family used across C-Class models of the same era.
We replace the timing chain, bearings and gaskets as standard on every M274 rebuild.
Source: established specialist pattern (per G-BRF, confirmed in original model page build). This issue applies to the M274 engine as used in the SLC200

Mercedes SLC200ENGINE OPTIONS
Every SLC200 is different. That's why we offer the right solution for your engine, your car and your budget.
REBUILDING YOUR SLC200 ENGINE
We rebuild the engine your SLC200 already has instead of selling you a used engine of unknown history — strip it down, pressure-test it, and replace every worn or damaged component (timing chains, bearings, water pump, gaskets) with updated OEM parts. Near-new performance with a 12-month unlimited-mileage warranty.
From £3,200RECONDITIONED SLC200 ENGINES
A full strip-down, inspection and replacement of worn parts rather than a straight swap. If that's what you're after, our rebuild service is exactly that.
Learn moreREFURBISHED SLC200 ENGINES
Restoring your existing engine to full working condition rather than replacing it outright. Our rebuild service covers this.
Learn moreREMANUFACTURED SLC200 ENGINES
Built to original specification with updated components. That's consistent with what our rebuild service delivers on the M256.
Learn moreREPLACEMENT SLC200 ENGINES
If your existing engine is beyond economical repair, we offer complete engine replacement and fitting – sourced and fitted by our team, with the same 12-month warranty.
Learn moreUSED SLC200 ENGINES
Matched low-mileage used engines for when time is critical. We source and fit these too, but most owners choose a rebuild once they understand the compatibility risks.

ABOUT THE MERCEDES SLC200 ENGINE

The SLC200 uses the M274 — a 2.0-litre turbocharged petrol 4-cylinder. It was fitted from 2016 to 2020 across the single R172 generation, which was itself the successor to the SLK. The SLC range was discontinued after this generation with no direct replacement, making the SLC200 one of a relatively short-lived but still widely owned model line. The M274 engine is shared with the C-Class of the same era, which is why its known wear patterns are well documented in specialist circles.
We continue to rebuild and replace M256 engines for every SLC200 on the road.
MERCEDES SLC200 ENGINE CODES

M256 (R190, 2023–present)
A 3.0-litre inline-six petrol mild-hybrid engine fitted to the SLC200 from 2023 to present. The M256 features an integrated starter-generator (ISG) and electric auxiliary compressor, making it a more modern and efficient design than the older M276 V6. We replace timing chains, bearings, water pump and gaskets as standard on every M256 rebuild.
Check Your M256 SLC200MERCEDES SLC200 ENGINE COMPATIBILITY

The SLC200 uses a single engine — the M274 2.0-litre turbocharged petrol 4-cylinder — across its entire production run. Before we quote or supply anything, we confirm:
Your exact engine code (M256) via registration or VIN
Your generation (R190)
Drivetrain and ancillary specification
Any electronics or ECU considerations specific to your exact build
This is why we always start with your registration rather than a generic SLC quote — it protects you from paying for parts that don't fit your actual car.
