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

Engine Finders connects UK drivers with vetted specialists for reliable, reconditioned Mercedes-Benz GLK-Class replacement engines. From the M272 V6 and M276 DE30 LA petrol engines to the OM642 and OM651 diesel powerplants found across the entire X204 chassis range (2008–2015), we address series-wide failure patterns that affect all GLK variants. Whether you're battling OM642 injector seal leaks common to early GLK320 CDI models or M276 balance shaft gear wear affecting all post-2011 GLK350s, Engine Finders makes it easy to locate the right engine, fast.

  • ✔ GLK-Class-Wide OM642 Injector Seal Failure Fix

    We replace degraded injector seals (OEM A6420500115) across all OM642-powered GLK320 CDI variants using updated Viton-spec components per Mercedes-Benz Service Campaign 201003001, eliminating chronic fuel leaks and misfires.

  • ✔ M276 Balance Shaft Gear Upgrade

    All M276 DE30 LA engines in GLK350 models (2011–2015) suffer from premature nylon balance shaft gear wear (OEM A2760500305). We install reinforced steel-gear kits compliant with Workshop Bulletin P-BE-02.12, resolving timing chain rattle and preventing catastrophic failure.

  • ✔ OM651 EGR Cooler Cracking Resolution

    The shared aluminum EGR cooler (OEM A6511400509) in all OM651-powered GLK220/250 CDI variants cracks due to thermal cycling stress. We retrofit stainless-steel units with integrated bypass valves, eliminating coolant contamination and head gasket damage.

  • ✔ M272 Variable Valve Timing Solenoid Recall Compliance

    Mercedes-Benz Recall 200902001 affects all M272 V6 engines in early GLK300 models. We install updated solenoids (OEM A2720510405) with revised internal filtration, preventing oil sludge buildup and cam phaser seizure across the entire X204 petrol range.

  • ✔ Unified Oil Pump Drive Chain System Repair

    Both OM642 and OM651 diesel engines share the same oil pump drive chain design (OEM A6420500215), prone to elongation after 90k miles. Our rebuilds include upgraded tensioners and duplex chains, addressing a root cause of low oil pressure across all GLK-Class diesels.

  • ✔ Turbocharger Wastegate Actuator Calibration

    All OM651 turbo variants (GLK220/250 CDI) use identical Garrett GT1549V turbos with failure-prone wastegate actuators (OEM A6510940109). We recalibrate actuator preload and install ceramic-coated levers, restoring boost control without ECU remapping.

  • ✔ Series-Specific Engine Mount Compatibility

    The X204 chassis uses unique hydraulic engine mounts (OEM A2042400405 for petrol, A2042400505 for diesel) across all GLK-Class variants. We verify mount compatibility during engine matching, preventing vibration transfer and subframe fatigue.

  • ✔ Cross-Variant Wiring Loom Integration

    Despite shared M272/M276/OM642/OM651 architectures, GLK-Class variants use distinct engine wiring harnesses (e.g., OEM A2045407605 for pre-2012, A2045408905 for post-2012). Our specialists ensure full CAN-bus compatibility, avoiding limp mode and immobiliser faults.

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

Engine Finders connects UK drivers with specialists for reliable, reconditioned Mercedes-Benz GLK-Class replacement engines. Whether battling M272 V6 balance shaft failures across early models or OM651 diesel injector issues in later variants, we provide direct OEM-spec solutions.

Mercedes-Benz GLK-Class Replacement Engines

The Mercedes-Benz GLK-Class (X204, 2008–2015) was the brand’s first compact SUV, built on the W204 C-Class platform and powered by two core engine families: the M272/M276 petrol V6s and the OM642/OM651 diesels. All M272 engines (2008–2011) suffered from balance shaft gear wear due to inadequate lubrication—a flaw addressed only in the updated M276 (2011–2015). Meanwhile, OM642 V6 diesels (2008–2011) shared injector and swirl flap failures with other Mercedes SUVs, while the four-cylinder OM651 (2011–2015) exhibited widespread injector coking and EGR cooler cracking across all power outputs. Technical Service Bulletin LI-10-01 specifically targeted M272 timing chain tensioner wear affecting all GLK 300/350 variants regardless of model year.

Mercedes-Benz GLK-Class Models & Engines Codes

Engine families span the entire GLK-Class production run, with shared components creating consistent failure patterns across trims:

  • M272E30/35: 3.0L/3.5L V6 petrol (GLK 300/350, 2008–2011) – Balance shaft gear (A2720500101) and timing chain tensioner (A2729970401) failures affect all variants
  • M276DE35: 3.5L V6 petrol (GLK 350, 2011–2015) – Direct injection carbon buildup and cam phaser wear common across all units
  • OM642DE30: 3.0L V6 diesel (GLK 320 CDI, 2008–2011) – Swirl flap linkage (A6420940015) and injector (A6420700717) failures identical to ML/GL-Class applications
  • OM651DE22: 2.2L I4 diesel (GLK 220/250 CDI, 2011–2015) – EGR cooler (A6510940115) cracks and injector coking (A6510700817) occur regardless of power output

All engines share mounting points and ancillary layouts with W204 C-Class counterparts, enabling cross-platform compatibility—but also propagating identical wear patterns.

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

For GLK-Class owners, used engines carry high risk due to systemic flaws in both M272 and OM651 families. Reconditioned units with updated balance shaft kits (A2720500101 revised) are essential for pre-2011 petrol variants, while OM651 diesel rebuilds must include upgraded EGR coolers (A6510940115) and decoked injectors to prevent repeat failures.

  • Reconditioned M272 engines: Include balance shaft elimination kit and reinforced timing components
  • Remanufactured OM651 engines: Feature updated EGR coolers and ultrasonically cleaned injectors
  • Used M276 engines: Require full carbon cleaning and cam phaser inspection before installation

All recommended solutions address root causes documented in Mercedes-Benz workshop manuals and verified by UK specialist workshops.

Mercedes-Benz GLK-Class Engines in Stock

Our reconditioned GLK-Class engines follow series-wide rebuild protocols based on TSB LI-10-01 and OM651 service updates:

  • M272: Balance shaft delete kit, new timing chain (A2729970401), and oil pump upgrade
  • OM651: Revised EGR cooler (A6510940115), injector recalibration, and DPF pressure sensor reset
  • All units: Full cylinder head refurbishment, gasket set replacement, and ancillary belt renewal

Every engine undergoes 4-hour dynamometer testing simulating real-world loads across GLK 220 CDI to GLK 350 power bands, with compression and leak-down results meeting Mercedes-Benz ISTA standards for the entire X204 series.

Warranty for Replacement Mercedes-Benz GLK-Class Engines

All rebuilt GLK-Class engines include a 12-month parts-and-labour warranty covering core mechanical components.

  • Exclusions: M272 balance shaft assemblies (design flaw per TSB LI-10-01), OM651 injectors in high-mileage (>120k) units
  • Warranty requires professional installation and post-fit diagnostic validation

Frequently Asked Questions - Mercedes-Benz GLK-Class Engines
How much does a GLK-Class N47D20C engine replacement cost in the UK?

Reconditioned pricing:
• £1,500–£1,800 for N47D20C engine (GLK-Class X204, 2010–2015)
• Includes updated timing chain tensioner (OEM 11347585994) specific to GLK-Class
• 12-month warranty included
• Save 35% vs main dealers through Engine Finders

What causes EGR valve failure in GLK-Class N47D20C engines?

The N47D20C in the GLK-Class uses a higher EGR flow rate than other variants due to stricter EU5 emissions tuning:
• Clogged EGR valves typically occur by 80,000 miles
• Mercedes-Benz Service Bulletin SWE-18-03 recommends revised EGR cooler (part 1350948301)
• Unique to X204 chassis – not seen in 116d or 118d

Is the N47D20C in GLK-Class the same as in 116d?

No – while sharing the same base code, the GLK-Class N47D20C has key differences:
• Higher boost pressure (1.8 bar vs 1.6 bar in 116d)
• Different camshaft profile affecting timing chain wear
• Unique oil pump drive gear (OEM 11347585995) prone to shearing in X204 only

When did GLK-Class switch from N47 to B47 engines?

The GLK-Class never used the B47 – it was discontinued in 2015 and replaced by the GLC-Class:
• Final N47D20C production: July 2015 (X204)
• B47 engines debuted in 2015 GLC (X253), not GLK
• Confusion arises because some importers rebadged early GLCs as “GLK”

What’s the timing chain fix cost for GLK-Class N47D20C?

Full timing system replacement for GLK-Class N47D20C:
• £850–£1,100 including labour (UK average)
• Must use OEM tensioner 11347585994 – aftermarket units fail within 10k miles
• Covered under Mercedes-Benz TSB SWE-18-01 for vehicles under 100k miles (pre-2013)

Why does my GLK-Class N47D20C lose power at 2,500 RPM?

This is a known failure mode tied to the X204-specific turbo actuator:
• Wastegate sticks due to carbon buildup from short trips
• Actuator rod (OEM A0000940201) seizes – unique to GLK-Class calibration
• Often misdiagnosed as fuel pump issue; requires VAG-COM adaptation reset

Does the GLK-Class 220 CDI use the M271 petrol engine?

No – this is a common misconception:
• All GLK-Class 220 CDI models use the N47D20 diesel engine
• Petrol GLKs are badged 200/250/350 and use M271/M272/M276
• “CDI” suffix exclusively denotes diesel in Mercedes-Benz nomenclature

What oil should I use in a GLK-Class N47D20C post-rebuild?

Only MB 229.51 or 229.52 spec oil is approved for rebuilt N47D20C in X204:
• Low-SAPS formula prevents DPF clogging (critical for GLK’s shorter exhaust)
• Avoid 5W-30 – use 0W-30 (e.g., Mobil 1 ESP 0W-30)
• Incorrect oil voids warranty on reconditioned engines

Are GLK-Class N47 engines affected by swirl flap failure?

Yes – but uniquely in the X204 chassis:
• Swirl flaps (part A6460940101) detach and enter combustion chamber
• Mercedes-Benz issued recall 2012R/08 specifically for GLK 220 CDI (2010–2012)
• Post-2013 models deleted flaps entirely – verify engine build date before purchase

Can I fit a 116d N47 engine into my GLK-Class?

Not without major modifications – the engines are not interchangeable:
• GLK-Class uses different engine mounts (part A2042000401 vs A0012000101 in 116d)
• Wiring harness pinouts differ due to 4MATIC AWD integration
• ECU coding requires X204-specific VIN alignment – fails immobiliser check otherwise
