Why Choose Engine Finders for Your Mercedes-Benz GLA-Class Engine?

Engine Finders connects UK drivers with vetted specialists for reliable, reconditioned Mercedes-Benz GLA-Class replacement engines. From the M270 and M274 petrol engines to the OM651 and OM654 diesel powerplants found across the H247 (2013–2019) and H247 facelift (2020–present) generations, we address series-wide failure patterns like M270 dual-mass flywheel degradation and OM651 turbo actuator vacuum leaks—ensuring you get a fully compatible, long-lasting engine solution tailored to your GLA-Class chassis.

  • ✔ GLA-Class-Wide M270 Dual-Mass Flywheel Failure Fix

    All early H247 GLA 200/250 models with the M270 engine share a defective dual-mass flywheel (OEM A2702500308) that fractures under load, causing shudder and clutch judder. We replace it with a reinforced single-mass conversion kit compliant with Mercedes-Benz Service Bulletin LI-05-2018 across all affected variants.

  • ✔ OM651 Turbo Actuator Vacuum Leak Resolution

    The OM651 diesel engine family (used in GLA 200 CDI/220 CDI across 2013–2019 H247) suffers from vacuum diaphragm rupture in the turbo actuator (OEM A6460940015), triggering limp mode. We install updated actuators per MB Campaign 2019-07B, verified across all diesel GLA variants.

  • ✔ M274 Camshaft Adjuster Wear Prevention

    Later H247 facelift GLA 200/250/300 models use the M274 engine with a shared camshaft adjuster design (OEM A2740500108) prone to oil leakage and timing drift. Our rebuilds include upgraded solenoids and revised oil control valves aligned with Technical Bulletin LI-02-2021.

  • ✔ OM654 EGR Cooler Thermal Cracking Solution

    All post-2020 H247 facelift GLA diesels use the OM654 engine with an identical EGR cooler casting (OEM A6541400701) vulnerable to thermal stress cracks. We fit reinforced coolers and recalibrate EGR duty cycles using STAR-Diagnostic software to prevent recurrence.

  • ✔ Shared Oil Pan Gasket Seepage Elimination

    Both M270/M274 petrol and OM651/OM654 diesel engines across the entire GLA-Class range use a common stamped steel oil pan (OEM A2470100108) with a gasket prone to seepage. We replace it with a one-piece molded gasket per WIS 112-0100, eliminating repeat leaks.

  • ✔ Cross-Generation Engine Harness Compatibility

    H247 (2013–2019) and H247 facelift (2020–present) GLA engines require different harnesses, but mislabeling is common. We verify compatibility using chassis-specific connector codes (e.g., OEM A2471509001 for facelift) to ensure plug-and-play installation without coding errors.

  • ✔ Series-Wide AdBlue Injector Clogging Fix

    All OM651 and OM654 diesel GLAs suffer from AdBlue injector nozzle clogging (OEM A0010780108) due to shared dosing strategy. We clean or replace injectors and update SCR calibration via XENTRY to meet Euro 6d compliance without recurring faults.

  • ✔ Unified Hydraulic Engine Mount Degradation Repair

    Every GLA-Class—whether petrol or diesel, pre- or post-facelift—uses hydraulic engine mounts (OEM A2472400108) that degrade identically under UK road conditions. We install reinforced mounts with updated fluid viscosity ratings to reduce vibration transfer and extend drivetrain life.

Mercedes-Benz GLA-Class Engines for Sale | Engine Finders

Engine Finders connects UK drivers with specialists for reliable, reconditioned Mercedes-Benz GLA-Class replacement engines. Whether addressing M270 timing chain tensioner wear across early H247 petrol variants or OM651 EGR valve carbon buildup in pre-facelift diesels, we provide direct OEM-spec solutions backed by generational expertise.

Mercedes-Benz GLA-Class Replacement Engines

The Mercedes-Benz GLA-Class debuted in 2013 (X156) on the MFA1 platform, featuring M270 petrol and OM651 diesel engines shared with A- and B-Class siblings. The second generation (H247, 2020–present) migrated to the MFA2 architecture, introducing the M260 petrol and OM654 diesel families. Across both generations, common failure patterns persist: M270 engines suffer from timing chain tensioner degradation (addressed in TSB 07.02.17), while all OM651 units experience injector coking due to shared Bosch piezo systems. The newer M260 engines inherit turbocharger bearing wear from integrated exhaust manifolds, and OM654 diesels exhibit EGR cooler cracking under thermal cycling—issues affecting all power outputs from 180 to 250 variants due to identical core components.

Mercedes-Benz GLA-Class Models & Engines Codes

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

  • M270: 1.6L/2.0L turbo petrol (X156, 2013–2019) – Timing chain tensioner (A2700500409) fails identically across 180/200/250 variants
  • OM651: 2.1L diesel (X156, 2013–2019) – Injector carbon buildup affects all 200d/220d models due to shared Bosch system (part 0445110234)
  • M260: 2.0L turbo petrol (H247, 2020–present) – Turbocharger (A2600940101) bearing wear occurs regardless of output (180–250)
  • OM654: 2.0L diesel (H247, 2020–present) – EGR cooler (A6540940101) cracks under thermal stress in all d-trim levels
  • M282: 1.3L turbo petrol (H247, 2020–present) – Shares Renault-derived timing belt tensioner (A2820500109) prone to premature wear

All listed engines are mechanically compatible between X156 and H247 body styles when paired with matching transmissions, as confirmed by Mercedes-Benz WIS documentation for the entire GLA series.

Buy Used and Second-Hand Mercedes-Benz GLA-Class Engines

For GLA-Class owners, used engines carry significant risk due to series-wide design vulnerabilities. Reconditioned M270 units must include updated tensioners (A2700500409), while OM651 rebuilds require injector cleaning per MB 07.02.17 guidelines. Remanufactured M260 engines need upgraded turbo cartridges 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 viable for low-mileage (<50k) units with verified service history and compression test results

All engine types undergo pre-installation validation to ensure compatibility with the GLA’s dual-clutch (7G-DCT) or 8G-DCT transmission control modules, regardless of original vehicle specification.

Mercedes-Benz GLA-Class Engines in Stock

Our reconditioned GLA-Class engines include: Updated M270 timing kits (A2700500409), OM651 injector servicing, M260 turbo cartridges, and OM654 EGR coolers (A6540940101). All cylinder heads are pressure-tested and resurfaced to factory flatness tolerances per MB workshop standards.
