Mercedes Viano 3.5 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 VIANO 3.5 uses a completely different engine family from the V8 M178 fitted to the Viano 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 Viano 3.5ENGINE OPTIONS
Every VIANO 3.5 is different. That's why we offer the right solution for your engine, your car and your budget.
REBUILDING YOUR VIANO 3.5 ENGINE
We rebuild the engine your VIANO 3.5 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 VIANO 3.5 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 VIANO 3.5 ENGINES
Restoring your existing engine to full working condition rather than replacing it outright. Our rebuild service covers this.
Learn moreREMANUFACTURED VIANO 3.5 ENGINES
Built to original specification with updated components. That's consistent with what our rebuild service delivers on the M256.
Learn moreREPLACEMENT VIANO 3.5 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 VIANO 3.5 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 VIANO 3.5 ENGINE

The Viano 3.5 uses the M272 — a 3.5-litre V6 petrol engine. It was fitted throughout the W639 generation from 2003 to 2014. The M272 was one of Mercedes' most widely used V6 petrol engines of the era, also appearing in the C-Class, E-Class, SLK and other models of that period. The Viano 3.5 represents the flagship petrol option in the Viano range.
We continue to rebuild and replace M256 engines for every VIANO 3.5 on the road.
MERCEDES VIANO 3.5 ENGINE CODES

M256 (R190, 2023–present)
A 3.0-litre inline-six petrol mild-hybrid engine fitted to the VIANO 3.5 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 VIANO 3.5MERCEDES VIANO 3.5 ENGINE COMPATIBILITY

Because the Viano 3.5 uses a single engine family across its production, we can confirm compatibility directly. 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 Viano quote — it protects you from paying for parts that don't fit your actual car.
