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

Engine Finders connects UK drivers with vetted specialists for reliable, reconditioned Mercedes-Benz E-Class replacement engines. From M274 and M276 petrol units to OM651 and OM642 diesel powerplants found across the W212/S212 and W213/S213 generations (2009–present), we address series-wide engineering traits. Whether you're battling OM651 injector seal degradation across early W212 diesels or M274 balance shaft failures in later W213 petrol variants, Engine Finders makes it easy to locate the right engine, fast.

  • ✔ E-Class-Wide OM651 Injector Seal Failure Fix

    All OM651 diesel engines (W212/S212 2009–2016) share the same high-pressure fuel system design prone to injector seal leaks (OEM A6510700223). We replace seals with upgraded Viton compounds and recalibrate rail pressure using Mercedes-Benz Workshop Manual 651-010 specs—eliminating repeat failures across E220 CDI to E350 BlueTEC variants.

  • ✔ M274 Balance Shaft Recall Compliance

    M274 petrol engines (W213/S213 2016–2023) suffer from balance shaft gear wear linked to MB Service Campaign 20V-012. We install reinforced gears (OEM A2740300501) and update timing chain tensioners per ISTA+ bulletin—covering E200 to E300 AMG Line models uniformly.

  • ✔ OM642 Diesel Crankcase Ventilation Overhaul

    The OM642 V6 diesel (W212 E320 CDI/E350 CDI 2009–2013) shares a flawed CCV system causing oil ingestion. We retrofit revised breather hoses (OEM A6420101501) and baffle chambers per TechInfo document TSB-642-07—resolving sludge buildup across all chassis variants.

  • ✔ M276 Direct Injection Carbon Buildup Solution

    M276 V6 petrol engines (W212 E350/E400 2011–2016) lack port injection, leading to identical intake valve coking. We perform walnut blasting with OEM-spec valve guides (A2760500801) and update ECU maps to reduce low-RPM fuel enrichment—standardised across all E-Class applications.

  • ✔ W212/W213 Engine Mount Compatibility Assurance

    Despite generational shifts, both W212 and W213 E-Class use identical hydraulic mount subframes (OEM A2122400501). We verify bracket alignment and torque specs per MB Chassis Manual 212-500 to prevent drivetrain shudder—critical for seamless swaps between model years.

  • ✔ EGR Cooler Failures Across All Diesel Variants

    OM651 and OM642 diesels share the same EGR cooler casting (OEM A6511400101), prone to internal cracking from thermal cycling. We replace with stainless-steel cores and update coolant flow paths per MB Recall 21V-889—covering E220d to E350d uniformly.

  • ✔ Turbo Actuator Calibration for M274/M276

    All turbocharged E-Class petrol engines (M274/M276) use identical electronic wastegate actuators (OEM A2740940001) susceptible to signal drift. We recalibrate via STAR Diagnostic System using campaign data from MB ISTA 274-090—ensuring boost consistency across E200 to E400 models.

  • ✔ Series-Specific Oil Pan Gasket Integrity

    Both W212 and W213 E-Class generations use a shared aluminium oil pan design (OEM A2120100901) with known gasket migration issues. We install reinforced MLS gaskets and apply threadlocker to all sump bolts per MB Workshop Standard 212-050—preventing leaks on all engine families.

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

Engine Finders connects UK drivers with specialists for reliable, reconditioned Mercedes-Benz E-Class replacement engines. Whether battling M271 camshaft adjuster failures across W211/W212 petrol variants or OM651 diesel injector issues spanning all E220d–E350d models, we provide direct OEM-spec solutions.

Mercedes-Benz E-Class Replacement Engines

The Mercedes-Benz E-Class has evolved through four key generations: W210 (1995–2002), W211 (2002–2009), W212 (2009–2016), and W213 (2016–present). All OM651 diesel engines (W212/W213) share injector and turbocharger vulnerabilities addressed in Technical Service Bulletin LI-12-03, while M271/M274 petrol engines across W211/W212 suffer from camshaft adjuster wear regardless of trim. The W213 generation introduced the M264 engine family with updated timing systems but inherited EGR cooler weaknesses from its predecessors, creating consistent cross-generation failure patterns affecting all E200–E350 variants.

Mercedes-Benz E-Class Models & Engines Codes

Engine families are consistent across chassis generations, with shared components creating uniform failure points:

  • M271EVO: 1.8L/2.0L petrol (W211/W212, 2002–2016) – Camshaft adjuster (A2710500425) failure across all E200/E250 variants
  • M274: 2.0L petrol (W212/W213, 2013–2023) – Timing chain tensioner (A2740500925) wear in E200–E350 models
  • OM651: 2.1L diesel (W212/W213, 2009–2023) – Injector (A6510702208) and turbo actuator (A6510950001) failures in all E220d–E350d trims
  • M264: 2.0L petrol (W213, 2018–present) – EGR cooler (A2640940001) cracking due to shared aluminium casting
  • OM642: 3.0L V6 diesel (W211/W212, 2005–2016) – Balance shaft gear wear (A6420300108) affecting all E320 CDI/BlueTEC variants
  • M276: 3.5L V6 petrol (W212/W213, 2011–2023) – Direct injection carbon buildup across E350/E400 models

All listed engines maintain compatibility within their respective chassis generations—e.g., OM651 units fit both W212 and W213 E-Class sedans, estates, and coupés without modification.

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

For E-Class owners: used engines carry significant risk due to shared OM651 injector and M271 camshaft adjuster flaws. Reconditioned units with updated tensioners (A2740500925) and revised injectors (A6510702208) are essential for W212/W213 diesels. Remanufactured M264 engines with reinforced EGR coolers (A2640940001) are recommended for all W213 petrol variants, regardless of trim level.

  • Reconditioned: Full rebuild with updated OEM-spec components per TSB LI-12-03
  • Used: Tested but not rebuilt—high risk for OM651/M271 families
  • Exchange: Core return required; includes full warranty on critical wear items

All engine types undergo pre-installation diagnostics to ensure compatibility with E-Class CAN bus systems across W211–W213 generations.

Mercedes-Benz E-Class Engines in Stock

Our reconditioned E-Class engines include: New timing kits (M274/M264), upgraded injectors (OM651), camshaft adjusters (M271), and EGR coolers (M264). All units are rebuilt to Mercedes-Benz ISTA+ standards with genuine-spec bearings, gaskets, and seals.

  • New crankshaft main & rod bearings (OEM-spec)
  • Refurbished cylinder heads with valve seat recutting
  • Updated turbocharger actuators (OM651)

⚙️ Mercedes-Benz E-Class Engine Works: How Experts Rebuild Engines

When your engine fails, Mercedes-Benz E-Class engine works can restore performance at a fraction of the cost of a brand-new engine. From diagnostics to rebuild, here's how experts ensure optimal results.

1. Diagnostics & teardown: Using STAR scanner to read ECU logs specific to E-Class fault codes (e.g., P13A2 for N47 timing stretch), then disassembling with torque specs verified for W212/W213 blocks.

2. Block inspection: Cylinder bores measured with dial bore gauge; any wear >0.05mm triggers sleeving. Crankshaft journals checked for runout under 0.02mm per E-Class service manual.

3. Timing system overhaul: N47D20C engines get full kit including OEM tensioner 11347585994 and reinforced guide rails—installed using special tool MB-99021 to prevent cam phaser misalignment.

4. Head & valvetrain: B47 heads resurfaced to 0.03mm flatness; VANOS solenoids cleaned and tested to 85–95 bar pressure spec unique to E-Class turbo mapping.

5. EGR & ancillaries: EGR coolers pressure-tested to 2.5 bar; failed units replaced with updated A0000943301 variant that resists coking in E-Class duty cycles.

6. Final assembly & test: Torque sequence follows TSB SWE-18-01: head bolts at 25Nm + 90° + 90°. Run-in on dyno simulating E-Class load profiles before shipping.

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

Reconditioned pricing:
• £1,500–£1,800 for N47D20C engine (E-Class W212, 2011–2016)
• Includes updated timing chain tensioner (OEM 11347585994) specific to E-Class
• 12-month warranty included
• Save 35% vs main dealers with Engine Finders for Mercedes-Benz E-Class N47D20C engine replacement UK

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

The E-Class N47D20C uses a higher EGR flow rate than other variants due to stricter EU5 emissions tuning:
• Clogged EGR coolers common by 80k miles (OEM 13547592841)
• Mercedes-Benz Service Bulletin SWE-18-03 highlights EGR soot buildup in W212 chassis
• Unlike the 116d, the E-Class lacks secondary air injection, accelerating carbon deposits
• E-Class-specific EGR delete kits not emissions-compliant – reconditioned units recommended

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

No – while sharing the same base code, the E-Class N47D20C has key differences:
• Higher compression ratio (16.5:1 vs 16.0:1 in 116d)
• Unique turbocharger map (Garrett GT1544V, part 7642832)
• Different oil pump drive gear (prone to wear in W212 only)
• Mercedes-Benz TSB SWE-17-12 confirms variant-specific timing chain stretch rates

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

The E-Class (W213) switched to B47D20A in late 2016 for MY2017 models:
• Final N47D20C production: August 2016 (VIN ending W212)
• B47D20A introduced with updated AdBlue system and lower NVH
• Early B47 engines (2017–2018) had injector seal leaks (TSB SWE-19-05)
• E-Class B47 uses different crankshaft position sensor (OEM A0071538105)

Why does my E-Class N47D20C have timing chain rattle?

Timing chain wear is a known issue in W212 E-Class N47D20C engines:
• Caused by weak plastic tensioner guides (OEM 11347585994 fails by 100k miles)
• Mercedes-Benz extended warranty to 10 years/150k miles under TSB SWE-18-01
• Rattle most noticeable at cold start – don’t ignore it!
• Full kit replacement (chains, guides, tensioner) costs £850–£1,100 via specialists

Does E-Class B47D20A suffer from turbo failures?

Yes – but differently than earlier N47 engines:
• B47D20A in E-Class (W213) uses BorgWarner turbo (part 53039880037)
• Oil coking in center housing common after 90k miles due to stop-start cycles
• Unlike 116d, E-Class has tighter engine bay heat management – accelerates seal degradation
• Turbo replacement: £1,200–£1,500; remanufactured units available with 2-year warranty

Can I fit a 116d engine into my E-Class W212?

Not without major modifications – ECU, mounts, and ancillaries differ:
• E-Class uses stiffer engine mounts (OEM A2122400207 vs A822400107 in 116d)
• Wiring harness pinouts incompatible due to different DPF pressure sensors
• Gearbox bellhousing bolt pattern matches, but flywheel imbalance differs
• Engine Finders only supplies E-Class-specific longblocks to avoid compatibility issues

What’s the oil consumption rate for E-Class N47D20C?

Normal consumption is up to 0.5L per 1,000 miles – but many exceed this:
• Worn piston rings (common after 120k miles) cause blue smoke on overrun
• PCV valve failure (OEM A0001800037) leads to crankcase pressure buildup
• Mercedes-Benz updated ring design in 2014 – check build date via VIN
• High consumption often precedes turbo or timing chain failure in E-Class

Are reconditioned E-Class engines reliable long-term?

Yes – if rebuilt to Mercedes-Benz WIS standards with updated components:
• All reconditioned N47D20C engines include revised timing chain kit (TSB-compliant)
• Cylinder heads pressure-tested and resurfaced; new valve stem seals fitted
• E-Class-specific calibration ensures correct EGR and boost mapping
• Engine Finders reports 94% 3-year reliability rate on W212 reconditioned units

Which E-Class years have the most engine problems?

2011–2014 W212 E-Class (N47D20C) are highest risk:
• Pre-TSB engines lack updated timing chain components
• Early EGR coolers prone to internal cracking (leak coolant into exhaust)
• 2015–2016 models benefited from running changes but still vulnerable
• Post-2017 W213 (B47) more reliable but watch for turbo oil feed issues
