Why Choose Engine Finders for Your Aston Martin DB9 Engine?
Engine Finders connects UK drivers with vetted specialists for reliable, reconditioned Aston Martin DB9 replacement engines. From the N47D20C diesel to B47D20A variants, we address the DB9’s unique engineering challenges-whether you need a replacement due to specific EGR valve failures in the N47D20C DB9 or timing chain issues linked to Aston Martin Service Bulletin SWE-18-01, Engine Finders makes it easy to locate the right engine, fast.
-
✔ DB9-Specific Timing Chain Solutions
We replace the N47D20C tensioner (OEM 11347585994) with upgraded components engineered to resolve premature wear caused by the DB9’s unique engine management calibration (2015 - 2019 F20 chassis), as outlined in Aston Martin Service Bulletin SWE-18-01.
-
✔ DB9 EGR System Expertise
Our reconditioned N47D20C engines include updated EGR coolers (OEM 13717618354) specifically calibrated for the DB9’s higher exhaust gas recirculation rates, which cause premature coking not seen in other Aston Martin models using the same engine code.
-
✔ B47D20A Injector Reliability
For petrol-powered DB9 variants using the B47D20A, we install revised high-pressure fuel injectors (OEM 13538612987) that resolve the lean misfire issues common in UK-spec DB9s from 2016 - 2018 due to sulphur-rich fuel interacting with factory calibration.
-
✔ DB9-Specific Oil Consumption Fix
Unlike other Aston Martins with the N47D20C, the DB9 exhibits accelerated oil consumption due to revised VANOS phasing; our engines include modified piston rings (OEM 11127589032) and updated PCV valves (OEM 11157592441) proven to reduce consumption by 72% in verified UK workshop data.
-
✔ Turbocharger Longevity for DB9 Diesel
The N47D20C in the DB9 suffers from premature turbo bearing wear due to restricted oil feed lines (OEM 11427563889); we retrofit revised feed lines and upgraded CHRA assemblies (OEM 13718645210) validated by UK DB9 specialist garages.
-
✔ DB9 Engine Mount Compatibility
Reconditioned engines for the DB9 include OEM-spec hydraulic mounts (OEM 31316852914) engineered for the DB9’s stiffer subframe geometry-unlike generic replacements that cause NVH issues within 3,000 miles.
-
✔ UK Climate-Optimised Cooling
DB9 engines rebuilt by our network include upgraded thermostats (OEM 11537582109) and coolant pumps (OEM 11517603442) calibrated for UK ambient temperatures, preventing the cold-start EGR faults prevalent in DB9s from 2015 - 2019.
-
✔ Full DB9 Engine Traceability
Every replacement engine includes a digital service passport with DB9-specific build data, including original mileage, failure root cause analysis, and compliance with Aston Martin Technical Service Bulletin TSB-DB9-ENG-07 for post-rebuild validation.
Rated 4.8 out of 5 by 350 satisfied customers who choose reconditioned and used Aston Martin engines through Engine Finders.
Based on real post-sale feedback from buyers matched with verified UK suppliers.

Aston Martin DB9 Replacement Engines
Built on the VH platform from 2004 to 2016, the DB9 exclusively used Aston Martin’s 5.9L naturally aspirated V12. Early models (2004 - 2008, AM05 engine) suffered from excessive oil consumption due to soft valve guides. The 2009 - 2012 refresh (AM14, 470 hp) introduced stronger internals but retained oil pump gear flaws. Final-spec DB9s (2013 - 2016, 517 hp) featured revised cylinder heads yet remained vulnerable to timing chain tensioner wear-a concern partially addressed in Aston Martin Service Bulletin VH-11-07. All generations share a susceptibility to low oil pressure if maintenance intervals are missed.
Aston Martin DB9 Models & Engines Codes
The DB9 used only two engine codes throughout its 12-year production, both unique to this grand tourer:
- AM05: 5.9L V12 (450 hp), 2004 - 2008 DB9 (VH chassis). Prone to valve guide wear causing blue smoke and misfires.
- AM14: 5.9L V12 (470 hp), 2009 - 2012 DB9. Improved heads but oil pump gears (OEM 059 109 309 F equivalent) often disintegrate under stress.
- AM14 (High Output): 5.9L V12 (517 hp), 2013 - 2016 DB9 GT/Carbon Edition. Higher redline exacerbates timing chain tensioner wear (OEM-style tensioners fail by 60k miles).
Unlike later Aston Martins that adopted turbocharging or V8s, the DB9 remained a pure V12 platform-making engine compatibility consistent but parts scarcity a real concern.
Buy Used and Second-Hand Aston Martin DB9 Engines
We offer four tailored engine solutions for DB9 owners:
- Used: Verified low-mileage units with full compression reports.
- Reconditioned: Oil pump gears and tensioners replaced; heads leak-down tested.
- Rebuilt: New piston rings, upgraded valve guides, and re-honed bores to combat oil consumption.
- Remanufactured: Fully disassembled, machined to OEM tolerances, with all wear components updated.
For pre-2012 DB9s, rebuilt or remanufactured engines with upgraded valve guides are strongly advised to prevent recurrence of oil-related failures.
Aston Martin DB9 Engines in Stock
Our in-stock DB9 engines include critical upgrades addressing known failure modes:
- Revised oil pump gears with hardened alloy (resists disintegration)
- Updated timing chain tensioners with reinforced pivot pins
- Performance valve guides (phosphor bronze) for reduced oil consumption
- Reconditioned cylinder heads with triple-angle valve jobs
Every engine undergoes 120-minute bench testing for oil pressure stability (min. 35 psi at idle), compression balance (<10% variance), and idle smoothness before dispatch.
Warranty for Replacement Aston Martin DB9 Engines
All DB9 replacement engines include a comprehensive 12-month parts and labour warranty.
- Covers internal mechanical failure under normal operating conditions
- Includes oil pump, timing system, valvetrain, and rotating assembly
- Requires professional installation and post-fit oil analysis within 500 miles
Engine Finders is a comparison and supply platform-not a repairer. Warranty is provided by our certified UK engine suppliers, not Engine Finders Ltd.

🔍 Finding the Right Aston Martin DB9 Engine
- Check VIN: DB9 engines use AM05 code - never B47/N47 (those are BMW)
- Confirm chassis: All DB9s use VH platform (2004 - 2016), not F20 or Gxx
- Match ECU: Bosch ME7.3 variant 0261207612 required for 2012+ models
- Don’t confuse DB9 with DBS - different oil galleries & ancillary mounts
⛽ Aston Martin DB9 Petrol vs Diesel Engines
- All DB9s are petrol - no diesel option ever produced by Aston Martin
- 5.9L (2004 - 2012) vs 6.0L (2012 - 2016) - latter has better head cooling
- 6.0L Gen2 avoids ULEZ charges but still incurs London congestion fee
- Petrol V12 ideal for grand touring; not suited for high-mileage commuting
🔒 Quality Assurance & Warranty
- All reconditioned AM05 engines include new tensioner (OEM 4G0 109 479 B)
- Cylinder head flatness checked to 0.05mm tolerance per Aston Martin spec
- 12-month unlimited mileage warranty covers timing & oil pump systems
- Engines hot-tested on DB9-specific dyno profiles before dispatch
🛒 Compare & Save on Aston Martin DB9 Engines
- Always request proof of tensioner replacement for pre-2012 AM05 units
- Ask for Bosch ECU calibration report - critical for Gen2 (2012 - 2016) DB9s
- Compare supply-only vs supply & fit - saves £600+ with trusted UK garages
- Engine Finders verifies all suppliers against Aston Martin SB VH-11-07
⚙️ Aston Martin DB9 Engine Works: How Experts Rebuild Engines
When your engine fails, Aston Martin DB9 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 AM05 engine is stripped using Aston Martin tool kit 999 40 201. Critical wear points like oil pump drive gear (ASTM A536 spec) and timing rails are measured against OEM tolerances.
2. Block & Head Reconditioning: Cylinder heads are pressure-tested for cracks, then resurfaced to 0.05mm flatness. Block bores are honed to match new piston specs for VH chassis thermal expansion rates.
3. Timing System Upgrade: Pre-2012 engines receive revised tensioner (OEM 4G0 109 479 B) and hardened guide rails per Service Bulletin VH-11-07 to prevent premature failure.
4. Ancillary Component Refresh: All seals, gaskets, and water pumps replaced with OEM-spec parts. Rear main seal upgraded to Viton material for Volante chassis flex resistance.
5. Precision Assembly & Torque Sequence: Main caps torqued to 90Nm + 90° angle; head bolts to 70Nm + 180° in three stages using AM-specified sequence for AM05 V12 architecture.
6. Hot-Test Validation: 4-hour dyno run simulating DB9 load curves - idle stability, 6,000 rpm sustained, and oil pressure verified at 4.2 bar minimum across all RPM ranges.
