Mercedes S580 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 S580 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.

Every S580 is different. That's why we offer the right solution for your engine, your car and your budget.

01MOST POPULAR

REBUILDING YOUR S580 ENGINE

We rebuild the engine your S580 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 £3,200

RECONDITIONED S580 ENGINES

REFURBISHED S580 ENGINES

Restoring your existing engine to full working condition rather than replacing it outright. Our rebuild service covers this.

USED S580 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 S580 ENGINE

Mercedes AMG GT 53 engine and sedan

The S580 is the flagship V8 variant of the W223-generation S-Class, introduced in 2021 as a replacement for the S560. For its first four years of production (2021 to 2025), it used the M176 — a 4.0-litre twin-turbo V8 with mild-hybrid assistance, the same engine family used in the preceding S560 and Maybach S580. From the 2026 model-year facelift, Mercedes introduced a running change to the M177 Evo, a more powerful 4.0-litre twin-turbo V8 with a flat-plane crank and revised hybrid system. The exact production changeover date hasn't been confirmed yet, so if your S580 is a 2026 model or later, we'll confirm which engine you have by registration before quoting.

We continue to rebuild and replace M256 engines for every S580 on the road.

MERCEDES S580 ENGINE CODES

M176

M176 (W223, 2021–2025)

A 4.0-litre twin-turbo V8 with mild-hybrid assistance, fitted to the S580 from the W223's launch in 2021 until the 2025 model-year. A proven, powerful V8 shared with the Maybach S580 and GLS 580.

MERCEDES S580 ENGINE COMPATIBILITY

Mercedes touring in workshop

Because the S580 spans two distinct V8 engines across a single generation, fitting the wrong replacement — or assuming an M176 part will work on an M177 Evo car — risks a compatibility problem that's expensive to unpick. 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.
