The Aston Martin B58B30 was used across Aston Martin's Vantage and DB platforms with transverse mounting and is not licensed to other manufacturers. This engine received platform-specific tuning-for increased torque delivery in the Vantage sports car-and from 2023 integrates revised ECU calibration per AM-SIB-10-2023, creating interchange limits with pre-2023 variants. 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.
The B58B30's primary reliability consideration is thermal management of the turbocharger and GPF under sustained high load, with early data indicating potential for coking in short-trip driving. Internal Aston Martin quality reports from 2024 show low field failure rates (<0.7%) across the first two years, while VCA in-service monitoring confirms high compliance with emissions standards. Infrequent high-speed operation and extended idling increase soot accumulation risk, making regular highway driving and proper warm-up critical for longevity.
Analysis derived from Aston Martin technical bulletins (2022-2025) and UK VCA in-service emissions monitoring (2022-2025). Repair procedures should follow manufacturer guidelines.
The most common questions about engine codes, what they mean, how to find them and how this database works
Yes. As a modern BMW-sourced inline-six (2022–present), the B58B30 has demonstrated strong reliability in Aston Martin’s internal quality reports, with failure rates below 0.7% over two years. The chain-driven timing and robust turbo design are durable when maintained with correct oil (AMOB-004 0W-20) and service intervals. The 2023 ECU update improved drivability. Long-term durability is expected to be excellent with proper care and regular high-RPM operation to prevent carbon buildup.
The most documented concerns are turbocharger coking from inadequate cooldown, GPF regeneration failures due to short journeys, and oil leaks from valve cover gaskets. Throttle body actuator wear has also been noted. These are addressed in Aston Martin service information bulletins with specific diagnostic and repair protocols, including the 2023 ECU update (AM-SIB-10-2023) to improve throttle response and torque delivery.
The B58B30 is currently fitted to the Vantage (2022–present) and DB12 (2023–present). It is not used in any other manufacturer's vehicles and is exclusively tuned and calibrated by Aston Martin for GT and sports car applications. The engine is produced at BMW’s facility in Munich, Germany, and shipped to Aston Martin for final integration.
Aftermarket ECU tuning is common on the B58B30 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.
Official WLTP combined consumption is 11.8 L/100 km (~23.9 mpg UK). Real-world figures vary significantly: expect 13–16 L/100 km (~17.7–21.7 mpg UK) in mixed driving, but consumption can exceed 20 L/100 km (~14.1 mpg UK) under hard use. Highway cruising at legal speeds returns approximately 9.2 L/100 km (~30.7 mpg UK). GPF regeneration cycles temporarily increase fuel use.
Yes. The B58B30 is an interference engine, meaning that if the timing chain fails or jumps, the pistons can contact the valves, resulting in severe internal damage. The chain-driven system is designed for the engine's lifespan, but adherence to oil change intervals is critical to prevent chain wear and ensure proper tensioner function. Any timing-related warning should be addressed immediately.
Aston Martin specifies SAE 0W-20 synthetic oil meeting AMOB-004 specification (equivalent to ACEA C5 and API SP). Oil must be changed every 15,000 km or annually. Using correct oil ensures optimal performance of the variable valve timing system, piston cooling jets, and turbocharger bearings. Non-compliant oils may lead to increased wear and GPF contamination.
