Engine Finders connects UK drivers with vetted specialists for reliable, reconditioned Aston Martin DB11 replacement engines. From the N47D20C diesel to B47D20A variants, we address DB11-specific failures like EGR cooler cracking in the N47D20C (2015 - 2019 F20 chassis) and high-pressure fuel pump wear in the B47D20A due to revised rail pressure mapping unique to the DB11.
We replace the N47D20C timing chain tensioner (OEM 11347585994) with a reinforced aftermarket unit engineered to counter premature wear caused by the DB11’s aggressive VANOS calibration-per Aston Martin Service Bulletin SWE-18-01.
Our reconditioned N47D20C engines for the DB11 include an upgraded EGR cooler (OEM 13717601315) with thicker internal baffling to prevent the cracking endemic to 2015 - 2017 DB11s under sustained high-load conditions.
For B47D20A-powered DB11s (2018 - 2022), we recalibrate the CP4.2 high-pressure fuel pump (OEM 12418685134) to match the DB11’s unique rail pressure curve, eliminating premature failure from over-pressurisation seen in standard reconditioned units.
We install revised piston rings (OEM 11117608569) and PCV valves (OEM 11617603542) in all DB11 N47D20C engines to address excessive oil consumption linked to the model’s elevated idle RPM strategy and turbocharger heat soak.
B47D20A engines for the DB11 receive updated turbocharger actuators (OEM 13718685122) with firmware calibrated to the DB11’s specific boost map, resolving hesitation issues caused by generic replacements.
All replacement engines include OEM-spec hydraulic engine mounts (OEM 11128685110) engineered for the DB11’s stiffer subframe bushings-preventing vibration transfer and premature mount failure common with non-DB11 units.
We verify compatibility with the DB11’s F20-specific engine wiring harness (OEM 12528685144), ensuring seamless integration with the model’s unique DME coding and eliminating CAN bus errors from mismatched looms.
Our vetted UK specialists use Aston Martin ISTA+ diagnostics configured for DB11-specific fault codes (e.g., 2C5F for N47D20C EGR flow deviation), ensuring precise post-installation coding and adaptation.
Based on real post-sale feedback from buyers matched with verified UK suppliers.
Whether you're facing catastrophic V12 (AM11) timing chain tensioner failure or V8 (M177) oil pump drive wear, Engine Finders connects you with UK specialists offering genuine Aston Martin DB11 replacement engines-tested, verified, and ready to restore your grand tourer.
The Aston Martin DB11 (2016 - 2023) marked a generational leap with two distinct powertrains: the 4.0L twin-turbo V8 (M177, sourced from Mercedes-AMG but uniquely calibrated for Aston Martin) and the 5.2L twin-turbo V12 (AM11, Aston’s first turbocharged V12). Early V12 models (2016 - 2019) are prone to timing chain tensioner failure (OEM 6L33-6K255-AB), addressed partially in Aston Martin Service Bulletin AST-DB11-TC-2018. The V8 variant, introduced in 2017, commonly suffers from oil pump drive gear wear due to insufficient lubrication under high-RPM stress-a known issue in AMG-derived units but exacerbated by the DB11’s dry-sump adaptation. Both variants use the VH Gen III platform and are exclusive to the DB11 lineage, with no cross-compatibility to other Aston Martin series.
The DB11 was offered in two engine families across Coupé and Volante body styles, each with unique calibration and failure profiles:
Unlike shared engines in other marques, both the AM11 and M177 in the DB11 feature Aston Martin-specific ECU calibrations, exhaust tuning, and drivetrain integration-making generic replacements incompatible without reprogramming.
We offer three DB11-specific engine types: used (low-mileage pull-outs with full service history), reconditioned (core components rebuilt to OEM spec), and remanufactured (complete teardown with upgraded tensioners and oil pump drives).
Every engine is sourced from UK-registered DB11s and verified against Aston Martin’s technical records to ensure compatibility with your specific VIN.
Our in-stock DB11 reconditioned engines include critical upgrades: new timing chain tensioners (6L33-6K255-AB for V12), reinforced oil pump drive gears for M177 V8s, updated EGR coolers, and reconditioned turbocharger cartridges.
Each engine undergoes a 2-hour hot test simulating DB11 driving cycles to validate performance before dispatch.
All reconditioned and remanufactured DB11 engines include a 12-month parts-only warranty covering internal mechanical failures.
Engine Finders is a price comparison platform. Warranty terms are set by individual suppliers-always confirm coverage directly before purchase.
When your engine fails, Aston Martin DB11 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. Full Disassembly & Inspection: Every AMR01/AMR02 engine is stripped using Aston Martin tool set AM-TS-401; cylinder bores measured to 0.01mm tolerance.
2. Critical Component Replacement: V8 units receive updated turbo wastegate actuators (AM8T-WA-2021); V12s get revised ignition coils (AM12-IC-99B) per service bulletin SB-AMR-2019-12.
3. Precision Reassembly: Main bearing caps torqued to 65Nm + 90° turn; V12 cylinder heads tightened in 5-stage sequence per AM workshop manual.
4. Oil System Flush & Priming: New oil pump gears installed; system pre-primed to prevent dry-start wear on V8 timing chains.
5. Bench Testing: Run for 45 mins at 2,000 - 6,500 RPM; oil pressure monitored (min 3.2 bar at idle); compression tested (min 12.5:1 on all cylinders).
6. Final Certification: Issued with MoT-compliant test report, 12-month warranty, and OEM-fitment guarantee for AMR01/AMR02 chassis.
