Mercedes GLA35 AMG 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 GLA35 AMG uses a completely different engine family from the V8 M178 fitted to the GLA-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 GLA35 AMGENGINE OPTIONS
Every GLA35 AMG is different. That's why we offer the right solution for your engine, your car and your budget.
REBUILDING YOUR GLA35 AMG ENGINE
We rebuild the engine your GLA35 AMG 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 GLA35 AMG 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.

Restoring your existing engine to full working condition rather than replacing it outright. Our rebuild service covers this.
Learn moreREMANUFACTURED GLA35 AMG ENGINES
Built to original specification with updated components. That's consistent with what our rebuild service delivers on the M256.
Learn moreREPLACEMENT GLA35 AMG 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 GLA35 AMG 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 GLA35 AMG ENGINE
The GLA35 AMG sits at the performance end of the GLA-Class range, offering AMG-badged performance in a compact SUV format. It uses the M139 — a 2.0-litre turbocharged petrol four-cylinder that's a genuine AMG engine, not a standard Mercedes unit with a badge. The M139 is hand-assembled and engineered for performance, which sets it apart from the standard 1.3-litre and 2.0-litre M260/M282 units fitted to the non-AMG GLA range. It's the same engine family that powers the GLA45 AMG, with tuning differences between the two.
We continue to rebuild and replace M256 engines for every GLA35 AMG on the road.
MERCEDES GLA35 AMG ENGINE CODES
M256 (R190, 2023–present)
A 3.0-litre inline-six petrol mild-hybrid engine fitted to the GLA35 AMG 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 GLA35 AMGMERCEDES GLA35 AMG ENGINE COMPATIBILITY
The GLA35 AMG uses a specific version of the M139 engine that's tuned differently from the GLA45 AMG's M139, with different boost and mapping characteristics. It's also distinct from the M260 and M282 engines used in the standard GLA200 and GLA250 — those are different designs entirely, not derivative of the AMG unit. 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 GLA-Class quote — it protects you from paying for parts that don't fit your actual car.
