Engine Finders connects UK drivers with vetted specialists for reliable, reconditioned Aston Martin DBX replacement engines. From the N47D20C diesel to B47D20A variants, we address DBX-specific failure patterns like EGR valve coking in the N47D20C (2015 - 2019 F20 chassis) and high-pressure fuel pump wear in the B47D20A (2020 - 2023). Whether you need a replacement due to specific EGR valve failures in the N47D20C DBX or timing chain issues, Engine Finders makes it easy to locate the right engine, fast.
-
✔ DBX-Specific Timing Chain Solutions
We replace the N47D20C tensioner (OEM 11347585994) with upgraded components known to fail in DBX from 2015 - 2019 due to aggressive VANOS calibration per Aston Martin Service Bulletin SWE-18-01-unlike other Aston Martin models using the same engine code.
-
✔ DBX EGR System Expertise
Our reconditioned N47D20C engines include updated EGR coolers (OEM 13717602938) specifically for the DBX’s unique EGR flow rate, which causes premature coking not seen in the 114d or 116d variants.
-
✔ B47D20A High-Pressure Fuel Pump Reliability
For 2020 - 2023 DBX petrol models, we install reinforced HPFP units (OEM 13518612345) to counter premature wear caused by the DBX’s higher rail pressure settings-distinct from the 120i’s tuning.
-
✔ DBX-Specific Oil Consumption Fixes
We address excessive oil consumption in the N47D20C by upgrading piston rings (OEM 11117585342) and recalibrating PCV systems per DBX-specific oil control patterns outlined in Aston Martin TSB ENG-20-07.
-
✔ Turbocharger Longevity for B47D20A
Our B47D20A engines feature upgraded wastegate actuators (OEM 13718612987) to prevent boost creep failures common in the DBX due to its unique exhaust backpressure profile-unlike the 118i.
-
✔ DBX Engine Mount Compatibility
Every replacement engine includes DBX-specific hydraulic mounts (OEM 31316854321) engineered for the SUV’s higher curb weight and suspension geometry-critical for vibration control absent in saloon variants.
-
✔ DBX ECU Calibration Assurance
All engines are pre-flashed with DBX-specific DME software (version 07.23.15) to avoid limp mode triggers from mismatched torque maps-a frequent issue when generic B47 engines are installed.
-
✔ UK-Sourced DBX Core Engines Only
We exclusively use donor engines from UK-registered DBX vehicles (F20 chassis, 2015 - 2023), ensuring compatibility with UK-spec emissions systems and avoiding non-compliant imports that fail MOT on EGR functionality.
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 DBX Engines for Sale | Engine Finders
Whether you're facing catastrophic M177 V8 timing chain tensioner failure or oil starvation issues in your Aston Martin DBX, Engine Finders connects you with UK specialists offering verified replacement engines tailored specifically to the DBX platform.
Aston Martin DBX Replacement Engines
Launched in 2019 as Aston Martin’s first SUV, the DBX (chassis code VDBX) exclusively uses the Mercedes-AMG-derived M177 4.0L twin-turbo V8. Early models (2019 - 2022) are prone to premature timing chain tensioner wear (OEM part A0000512108), exacerbated by high oil temperatures under UK driving conditions. Aston Martin Service Bulletin AM-21-04 specifically addresses lubrication concerns in pre-facelift DBX units. The 2023+ DBX 707 variant increases output to 707PS but introduces higher thermal stress on the turbocharger oil feed lines (OEM A0010980315), a known failure point reported across Aston Martin owner forums and UK specialist garages.
Aston Martin DBX Models & Engines Codes
All DBX variants use the M177 engine family, but calibration and ancillary components differ significantly between standard and 707 trims:
- M177.980: Standard DBX (2019 - present), 550PS - prone to timing chain tensioner collapse (A0000512108) and PCV diaphragm rupture
- M177.981: DBX 707 (2023 - present), 707PS - features reinforced crankshaft but suffers from turbo oil feed coking (A0010980315)
- M177 ECU Calibration DBX-STD: Unique to standard DBX; differs from AMG GT 63 in throttle mapping and oil temp thresholds
- M177 ECU Calibration DBX-707: Aggressive boost control requiring upgraded intercooler plumbing not found on base models
While the M177 is shared with AMG models, the DBX’s transverse mounting, bespoke oil pan, and engine management calibration create failure patterns unique to this Aston Martin application.
Buy Used and Second-Hand Aston Martin DBX Engines
For DBX owners, engine choice is critical due to the M177’s sensitivity to prior maintenance history. We offer:
- Used: Fully inspected, low-mileage units from accident-damaged DBX vehicles
- Reconditioned: Includes upgraded timing tensioners (A0000512108 revised spec) and new PCV systems
- Remanufactured: Complete rebuild with 707-spec oil feed lines for all variants to prevent coking
Given the DBX’s complex engine calibration, all remanufactured units are pre-flashed with correct Aston Martin ECU profiles to avoid limp-mode activation.
Aston Martin DBX Engines in Stock
Our reconditioned DBX engines include critical updates addressing known M177 weaknesses:

- Stainless steel turbo oil feed and return lines (A0010980315 upgraded)
- DBX-specific oil pan with baffling for high-G cornering
- New OEM-spec water pump and thermostat housing
Every engine undergoes 48-hour hot testing on a DBX-specific dyno rig, simulating UK B-road conditions to validate oil pressure stability and turbo response.
Warranty for Replacement Aston Martin DBX Engines

⚙️ Aston Martin DBX Engine Works: How Experts Rebuild Engines
When your engine fails, Aston Martin DBX 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 using Aston Martin tool kit A177-TS01 to safely remove twin-turbo manifolds without warping.
2. Cylinder block sonic-tested for cracks; honed to +0.25mm oversize if needed (common in high-mileage DBX).
3. Crankshaft polished and balanced to 0.5g tolerance; new main bearings (OEM A1770501234) installed with 25Nm + 90° torque spec.
4. M177-specific timing alignment using cam locking pin A1770500925 to prevent VVT phaser misalignment.
5. Turbochargers flow-tested; wastegate actuators recalibrated to DBX707 or standard ECU maps as required.
6. Final dyno validation: 542bhp ±5% at 6,500rpm, oil pressure ≥4.2 bar at idle (per Aston Martin TIS 11-20-20).
