Mercedes Maybach S680 Oil Leaks & Coolant System Wear (M256 I6)
The M256 is a sophisticated 3.0-litre inline-six with an integrated starter-generator and electric auxiliary compressor — 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.
Because the MAYBACH S680 uses a completely different engine family from the V8 M178 fitted to the S-Class 63 and GT 63 S, parts and rebuild specifications don't cross over between them.
Source: Established M256 specialist pattern — timing chain, bearing and gasket wear across integrated-starter-generator inline-six units.
Mercedes Maybach S680ENGINE OPTIONS
Every MAYBACH S680 is different. That's why we offer the right solution for your engine, your car and your budget.
REBUILDING YOUR MAYBACH S680 ENGINE
We rebuild the engine your MAYBACH S680 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 MAYBACH S680 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.

ABOUT THE MERCEDES MAYBACH S680 ENGINE
The Maybach S680 is the pinnacle of the S-Class range, powered by a 6.0-litre twin-turbo V12. Introduced in 2021 for the Z223 generation, it continues a long Mercedes tradition of V12 luxury flagships. The engine represents the highest level of complexity and cost in the S-Class line-up, with components and labour costs reflecting its bespoke nature. The Maybach S680 is no longer in production, but we continue to rebuild and replace engines for every one still on the road.
We continue to rebuild and replace M256 engines for every MAYBACH S680 on the road.
MERCEDES MAYBACH S680 ENGINE CODES
M256 (R190, 2023–present)
A 3.0-litre inline-six petrol mild-hybrid engine fitted to the MAYBACH S680 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 MAYBACH S680MERCEDES MAYBACH S680 ENGINE COMPATIBILITY
The Maybach S680's V12 engine is unique to the Z223 generation. Fitting an engine from a different model, or even a different S-Class variant, would be incompatible due to significant differences in mounting, electronics, and ECU calibration. 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 S-Class quote — it protects you from paying for parts that don't fit your actual car.
