The Alfa Romeo VM 08 B is a 2,445 cc, inline — four turbocharged diesel engine produced between 1989 and 1996. Developed by VM Motori in collaboration with Alfa Romeo, it features indirect injection, a Bosch VE distributor — type injection pump, and a Garrett T3 turbocharger. In standard tune it delivers 81 kW (110 PS), with torque output of 240 Nm available from 2,000 rpm.
Fitted to the Alfa Romeo 75 (930) and 75 Turbo Diesel models, the VM 08 B was engineered for durability and st…

The Alfa Romeo VM 08 B is a 2,445 cc inline‑four turbocharged diesel engine engineered for mid-size passenger cars (1989–1996). It combines indirect injection with a mechanical distributor pump and fixed-geometry turbocharging to deliver dependable torque and longevity. Designed to meet Euro 1 emissions standards, it prioritizes mechanical simplicity and serviceability.

The Alfa Romeo VM 08 B was used in Alfa Romeo's 930 platform with longitudinal mounting and rear-wheel-drive layout. This engine received platform-specific adaptations—reinforced engine mounts in the 75 Turbo Diesel and revised exhaust manifolds for improved turbo spool. From 1993, the facelifted 75 adopted a revised EGR system and upgraded coolant pump, 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 VM 08 B is a mechanically simple and durable diesel engine. When maintained properly—with regular timing belt changes, coolant flushes, and use of API CF-2 oil—it can exceed 300,000 km. Early models (1989–1992) had head gasket concerns, but later revisions resolved this. No widespread electronic issues exist due to mechanical fuel control. It remains a robust choice for enthusiasts and restorers.
The most frequent issues are head gasket failure (pre-1992), timing belt wear, turbo oil seal leakage, and injection pump wear. These are documented in Alfa Romeo service bulletins, particularly Technical Bulletin 75/1992 for the head gasket upgrade. The mechanical nature of the engine makes diagnosis straightforward, but parts availability requires specialist sourcing.
This 2.5L turbo diesel engine was used exclusively in the Alfa Romeo 75 (930) model from 1989 to 1996. It powered the 75 2.5 TD variant, offering 110 PS and 240 Nm of torque. Production spanned 1989–1996, with all models meeting Euro 1 emissions standards. The engine was later replaced by the VM 12 series in updated applications.
Limited tuning potential exists. The Bosch VE pump can be recalibrated for +10–15 kW, but this increases stress on the head gasket and turbo. Enthusiasts often upgrade the intercooler, exhaust, and injectors for modest gains. Due to the mechanical nature of the engine, ECU remapping is not applicable. Any tuning should maintain fuel quality and include upgraded cooling to manage increased thermal load.
Moderate. In the Alfa Romeo 75 2.5 TD, combined consumption is ~8.2 L/100km (~34 mpg UK). City driving may see 9–10 L/100km, while highway runs can achieve 7.0 L/100km. Real-world figures depend on driving style, but expect 30–35 mpg (UK) on mixed routes for a healthy engine. The mechanical injection system is less efficient than modern common-rail diesels but highly reliable.
Yes. The VM 08 B is an interference engine. If the timing belt fails or jumps, pistons can collide with open valves, causing catastrophic internal damage. Proper maintenance and timely replacement of the timing belt (every 60,000 km) are essential to prevent costly repairs. The front-mounted belt design allows relatively straightforward access for replacement.
Alfa Romeo specifies SAE 15W-40 mineral oil meeting API CF-2 standards. Use only diesel-rated oils designed for high-load turbocharged engines. Change intervals should not exceed 15,000 km or 12 months to ensure turbo and bearing lubrication and prevent deposit formation. API CF-2 is critical for protecting the injection pump from wear.
