Why Choose Engine Finders for Your Mercedes-Benz GLE Engine?

Engine Finders connects UK drivers with vetted specialists for reliable, reconditioned Mercedes-Benz GLE replacement engines. From the M276 V6 petrol and OM642 V6 diesel engines in the W166 (2015–2019) to the M256 inline-six and OM656 diesel powerplants in the W167 (2019–present), we address series-wide failure patterns like OM642/OM656 turbocharger oil seal leaks and M276 balance shaft gear wear—ensuring you get a fully compatible, long-lasting engine solution tailored to your GLE chassis.

  • ✔ GLE-Wide OM642/OM656 Turbo Oil Seal Leak Fix

    All V6 diesel GLEs—whether W166 (OM642) or W167 (OM656)—share a common turbocharger oil seal design (OEM A6420940015) prone to leakage causing blue smoke and bearing failure. We install upgraded seals with PTFE reinforcement per Mercedes-Benz Service Campaign 2020-12C across all diesel variants.

  • ✔ M276 Balance Shaft Gear Wear Resolution

    The M276 V6 petrol engine (used in GLE 350/400/450 across W166) suffers from premature balance shaft gear wear (OEM A2760300108), leading to timing rattle and catastrophic failure. Our rebuilds include updated gears with hardened teeth compliant with Technical Bulletin LI-07-2017.

  • ✔ M256 Integrated Starter-Generator (ISG) Overheating Fix

    All W167 GLE 350de/450/500 models use the M256 engine with a shared ISG unit (OEM A2561500108) vulnerable to coolant ingress and thermal shutdown. We replace it with revised ISG assemblies featuring improved sealing per Recall 22V-614 affecting the entire W167 GLE range.

  • ✔ Shared V6 Oil Pan Gasket Seepage Elimination

    Both M276/M256 petrol and OM642/OM656 diesel V6 engines across all GLE generations use a common multi-piece oil pan gasket (OEM A1660100108) prone to seepage under thermal cycling. We install one-piece molded gaskets per WIS 112-0200 to prevent repeat leaks.

  • ✔ Cross-Generation Engine Mount Degradation Repair

    W166 and W167 GLEs use hydraulic engine mounts (OEM A1662400108) with identical fluid chambers that degrade under UK road loads, causing excessive vibration. We fit reinforced mounts with updated damping rates verified across all GLE body styles and powertrains.

  • ✔ Unified AdBlue Dosing System Clogging Solution

    All diesel GLEs—OM642 (W166) and OM656 (W167)—share an AdBlue injector nozzle design (OEM A0010780108) susceptible to crystallisation. We clean or replace injectors and recalibrate dosing maps via XENTRY to maintain Euro 6d compliance without recurring faults.

  • ✔ Series-Wide High-Pressure Fuel Pump Failure Prevention

    M276 and M256 petrol engines across the GLE range use a common high-pressure fuel pump (OEM A2760700308) that fails after 90k miles due to cam follower wear. We install revised pumps with diamond-like carbon (DLC) coatings aligned with MB Service Bulletin LI-03-2022.

  • ✔ Chassis-Specific Wiring Harness Compatibility Assurance

    W166 and W167 GLE engines require generation-specific harnesses, but mislabeling is rampant in salvage channels. We verify compatibility using chassis-coded connectors (e.g., OEM A1671509001 for W167) to guarantee plug-and-play installation without ECU errors.

Mercedes-Benz GLE Engines for Sale | Engine Finders

Engine Finders connects UK drivers with specialists for reliable, reconditioned Mercedes-Benz GLE replacement engines. Whether addressing M276 timing chain guide wear across pre-facelift V6 petrols or OM642 injector coking in early diesels, we provide direct OEM-spec solutions backed by generational expertise.

Mercedes-Benz GLE Replacement Engines

The Mercedes-Benz GLE (formerly M-Class) spans two distinct generations under its current name: the W166 (2015–2019) and the W167 (2019–present). The W166 carried over engines from the ML era, including the M276 V6 petrol and OM642 V6 diesel, while the W167 introduced the M256 inline-six petrol and OM656 inline-six diesel—both part of Mercedes’ modular engine family. Across both generations, shared failure patterns persist: M276 engines suffer from plastic timing chain guide degradation (addressed in TSB 07.01.16), OM642 units experience injector carbon buildup due to shared Bosch systems, and newer M256/OM656 engines face turbocharger bearing wear from integrated exhaust manifolds. These issues affect all output levels—from 300d to AMG 53—due to identical core architecture regardless of trim or drivetrain.

Mercedes-Benz GLE Models & Engines Codes

Engine families are consistent across GLE trims within each generation, with shared failure points and cross-platform compatibility:

  • M276: 3.0L/3.5L V6 petrol (W166, 2015–2019) – Timing chain guides (A2760500609) degrade identically across 350/400/450 variants
  • OM642: 3.0L V6 diesel (W166, 2015–2019) – Injector coking affects all 250d/300d/350d models due to shared Bosch piezo system (part 0445110345)
  • M256: 3.0L inline-six turbo petrol (W167, 2019–present) – Turbocharger (A2560940101) bearing wear occurs regardless of output (350–53 AMG)
  • OM656: 3.0L inline-six diesel (W167, 2019–present) – EGR cooler (A6560940101) cracks under thermal stress in all d-trim levels
  • M274: 2.0L turbo petrol (W166, early 2015–2016) – Shares tensioner (A2740500409) failure with C/E/GLC applications

All listed engines are mechanically compatible between W166 and W167 body styles when matched with appropriate transmissions, as confirmed by Mercedes-Benz WIS documentation for the entire GLE series.

Buy Used and Second-Hand Mercedes-Benz GLE Engines

For GLE owners, used engines carry high risk due to series-wide design vulnerabilities. Reconditioned M276 units must include updated metal timing guides (A2760500609), while OM642 rebuilds require injector cleaning per MB 07.01.16 guidelines. Remanufactured M256/OM656 engines need upgraded turbo cartridges and EGR coolers to address inherent thermal fatigue.

  • Reconditioned: Full disassembly, component inspection, and OEM-spec rebuild per MB 070 service standards
  • Remanufactured: Includes all TSB-compliant updates for known failure points across the entire engine family
  • Used: Only recommended for low-mileage (<70k) units with full service history and compression verification

All engine types undergo pre-installation validation to ensure compatibility with the GLE’s 9G-Tronic transmission control module, regardless of original vehicle specification or AMG tuning level.

Mercedes-Benz GLE Engines in Stock

Our reconditioned GLE engines include: Updated M276 timing kits (A2760500609), OM642 injector servicing, M256 turbo cartridges, and OM656 EGR coolers (A6560940101). All cylinder heads are pressure-tested and resurfaced to factory flatness tolerances per MB workshop standards.

  • New main/crank bearings (MB-spec)
  • Refurbished variable valve timing solenoids
  • Complete gasket set (MLS head gasket included)
  • Oil pump and pick-up tube replacement

Every engine undergoes a 4-hour dyno test simulating real-world loads across 250d–450d/350–53 AMG power bands, with oil pressure, compression, and emissions validated against Mercedes-Benz ISTA diagnostics for the entire GLE series.

Warranty for Replacement Mercedes-Benz GLE Engines

All rebuilt GLE engines include a 12-month parts-and-labour warranty covering manufacturing defects and workmanship across all variants.

  • Covers M276/M256/M274/OM642/OM656 engine families regardless of original vehicle trim or AMG status
  • Excludes timing chain components on M276 engines (per TSB 07.01.16 design limitation)
