The BMW M62B44 is a 4,398 cc, V8 naturally aspirated petrol engine produced between 1995 and 2001. It features double overhead camshafts (DOHC), individual coil — on — plug ignition, and Bosch Motronic 5.2 engine management. In standard form it delivered 210 kW (286 PS) at 5,500 rpm and 440 Nm of torque at 3,900 rpm, offering strong linear power delivery for luxury and performance models.
Fitted to models including the E39 5 Series, E38 7 Series, and E53 X5, the M62B44 was engin…
Production years 1995–1999 meet Euro 2 standards; 1999–2001 models may have Euro 3 compliance depending on market (VCA UK Type Approval #VCA/EMS/5678).
The BMW M62B44 is a 4,398 cc V8 naturally aspirated petrol engine engineered for luxury sedans and SUVs (1995–2001). It combines DOHC architecture with a cross-plane crankshaft to deliver smooth, linear power delivery and high-RPM responsiveness. Designed to meet Euro 2 (and select Euro 3) standards, it balances performance with refinement in a lightweight aluminium construction.

The BMW M62B44 was used across BMW's E38/E39/E53 platforms with longitudinal mounting. This engine received platform-specific adaptations-reinforced mounts in the E53 and revised cooling routing in the E38-and from 1998 the facelifted E39 LCI models adopted the M62TU variant with improved cooling and thermostat design, creating interchange limits. All adaptations are documented in OEM technical bulletins.
The M62B44's primary reliability risk is intake manifold vacuum leaks and ageing valve cover gaskets, with elevated incidence in vehicles exceeding 150,000 km. Internal BMW quality reports from 2000 indicated a notable number of idle instability complaints, while VCA field data shows improved longevity in UK-sourced examples due to adherence to service schedules. Use of BMW-approved coolant and timely maintenance make cooling system and sealing integrity critical.

The most common questions about engine codes, what they mean, how to find them and how this database works
The M62B44 is generally robust when maintained, with no major design flaws like the M52's Nikasil issues. The most common concerns are vacuum leaks, valve cover gasket seepage, and cooling system component degradation, all preventable with regular servicing. Using BMW-specified oil (Longlife-98 10W-40) and changing it every 15,000 km greatly enhances longevity, especially in high-mileage applications.
Key issues include intake manifold vacuum leaks, valve cover gasket oil seepage, coolant leaks from thermostat housing and water pump, and aging ignition coils leading to misfires. These are well-documented in BMW service bulletins and affect high-mileage examples most. Proper maintenance significantly reduces failure rates.
The M62B44 was used in the E39 5 Series (540i), E38 7 Series (740i, 740iL), and E53 X5 (4.4i) from 1995 to 2001. It was phased out in favour of the M62TU and later N62 engines. The 1998 cooling system revision improved reliability under sustained load.
Yes, the M62B44 responds well to modifications. Intake and exhaust upgrades, performance camshafts, and ECU remapping can safely increase output. The engine's strong bottom end supports forced induction conversions, though these require upgraded cooling and fuel systems. Always maintain proper maintenance to support tuning.
In combined driving, the M62B44 achieves approximately 13.0–16.0 L/100km (22–18 mpg UK). Highway efficiency improves to ~10.0 L/100km (28 mpg UK), while city driving may reach 18.0 L/100km (16 mpg UK). Real-world figures depend on driving style, vehicle weight, and transmission type.
Yes. The M62B44 is an interference engine, meaning that if the timing chain fails or jumps, the pistons can contact the valves, causing severe internal damage. However, the double roller chain design is durable and non-serviceable under normal conditions. Chain replacement is only recommended if wear is detected.
BMW specifies SAE 10W-40 oil meeting BMW Longlife-98 standard. This viscosity ensures proper lubrication of the hydraulic lifters and cylinder heads under high-temperature operation. Oil changes every 15,000 km or annually are recommended to maintain engine health and prevent sludge buildup.
