The Aston Martin TB04-12 is a 3,998 cc twin-turbocharged V8 petrol engine engineered for high-performance grand touring and SUV applications (2020–2025). It features a 90° aluminum block, DOHC 32-valve heads, and hot-V turbocharging with dual-scroll turbines to deliver strong low-end torque and responsive power delivery. Co-developed with Mercedes-AMG (M177 basis), it meets Euro 6d standards while supporting advanced thermal management and GPF integration.

The Aston Martin TB04-12 was used across Aston Martin's VH and ML3 platforms with longitudinal mounting and co-developed with Mercedes-AMG as part of the M177 family. This engine received model-specific calibrations-intake tuning in the Vantage and revised exhaust manifolds in the DBS Superleggera-and from 2022 the DBX707 adopted the TB04-12 HP variant with higher boost and revised cam profiles, creating interchange limits. All adaptations are documented in OEM technical bulletins.
Engine Finders UK Ltd, which operates EngineCode.uk, can pass your enquiry to engine suppliers in the UK. The service is for vehicles in the United Kingdom, with UK delivery or fitting. This is a commercially connected service, and sending an enquiry does not confirm diagnosis or compatibility.
Diagnostic reminder: If a technician has recommended replacing the engine, you can send an enquiry to engine suppliers in the UK. Confirm the diagnosis first: an engine-code record does not diagnose a fault.
Field reports and technical service bulletins highlight component wear patterns under high-load operation. Adherence to manufacturer service intervals and approved fluid specifications is critical for long-term reliability.

The most common questions about engine codes, what they mean, how to find them and how this database works
The TB04-12 is generally robust when properly maintained, but pre-2021 DBX models are prone to intercooler hose detachment under high boost. Later revisions (post-2021) improved clamping hardware. Regular oil changes with correct 0W-40 specification and cooling system maintenance are essential. Well-serviced engines can exceed 120,000 km without major issues.
The most frequent issues are intercooler hose detachment (especially in early DBX), oil consumption in high-mileage engines, cooling system leaks, and throttle body motor wear. These are documented in Aston Martin service bulletins and supported by dealer repair records.
The TB04-12 powers the DB11 V8 (2020–2025), DBS Superleggera (2020–2025), Vantage (2020–2025), and DBX (2020–2025), including the DBX707. It is co-developed with Mercedes-AMG (M177 basis) but features Aston Martin-specific calibration and intake systems.
Aftermarket ECU tuning is common on the TB04-12 platform, but increasing boost or altering engine parameters accelerates component wear, impacts emissions compliance, and may void vehicle warranties. Any modifications should be evaluated carefully by a qualified specialist.
Moderate for a high-performance twin-turbo V8. In a DB11 V8, expect ~14.8 L/100km (city) and ~9.3 L/100km (highway), or 19 mpg UK combined. The heavier DBX consumes more, around ~16.5 L/100km in mixed driving. Real-world consumption depends heavily on driving style and fuel quality.
Yes. The TB04-12 is an interference engine. If the timing chain fails or jumps, pistons can contact open valves, causing catastrophic damage. Chain replacement is recommended every 120,000 km or 10 years, whichever comes first.
Aston Martin specifies Mobil 1 0W-40 meeting WSS-M2C949-A2 standard. Oil must be changed every 12,000 km or 1 year. Using incorrect oil can accelerate turbo bearing and chain wear due to the high-temperature, high-pressure environment of the twin-turbo V8.
