The BMW M62 B35 (358S2) is a 3,498 cc, naturally aspirated V8 petrol engine produced between 1996 and 2001. It features DOHC, 32 — valve configuration with individual throttle bodies and Bosch Motronic 4.4 electronic fuel injection. Rated at 170 kW (231 PS) and 350 Nm of torque, this engine delivers smooth, linear power delivery ideal for grand touring applications.
Fitted primarily to the E39 5 Series and E38 7 Series, the M62 B35 was engineered for refined performance and d…
Production years 1996–2001 meet Euro 2 emissions standards (VCA UK Type Approval #VCA/EMS/5679).
The BMW M62 B35 (358S2) is a 3,498 cc V8 naturally aspirated petrol engine engineered for luxury sedans (1996–2001). It combines dual overhead camshafts with individual throttle bodies to deliver smooth, high-revving performance. Designed to meet Euro 2 standards, it balances refinement with strong mid-range power for effortless cruising.

The BMW M62 B35 (358S2) was used across BMW's E38/E39 platforms with longitudinal mounting and no licensed external applications. This engine received platform-specific adaptations-revised cooling routing in the E38 and shorter accessory drives in the E39-and from 1999 the facelifted E39 LCI adopted the M62TU variant with revised cylinder head and VANOS, creating interchange limits. All adaptations are documented in OEM technical bulletins.
The M62 B35's primary reliability risk is timing chain guide wear in early builds, with elevated incidence in high-mileage vehicles. Internal BMW quality reports from 1998 noted a significant share of pre-1998 engines requiring guide replacement before 150,000 km, while UK DVSA records show low emissions-related failures due to robust catalytic converter design. Extended oil intervals and short-trip driving increase chain stress, making oil quality and change frequency critical.

The most common questions about engine codes, what they mean, how to find them and how this database works
The M62 B35 is generally robust, but early models (1996–1998) are prone to timing chain guide wear. Later revisions (post-1998) with reinforced nylon guides significantly enhance longevity. Regular oil changes with BMW Longlife-98 spec oil and avoiding short trips help prevent premature wear. Well-maintained engines often exceed 200,000 km.
Key issues include premature timing chain guide wear (pre-1998), coolant leaks from plastic intake manifold gaskets, VANOS solenoid clogging, and valve cover oil leaks. These are documented in BMW service bulletins and confirmed by long-term owner data. The intake manifold issue is particularly common due to material degradation.
The M62 B35 was used in the E39 5 Series (535i) and E38 7 Series (735i) from 1996 to 2001. It replaced the M60B35 and was later superseded by the M62TU with updated VANOS and cylinder head. All applications meet Euro 2 emissions standards.
Yes, though naturally aspirated. Performance gains come from camshaft upgrades, ported heads, and exhaust modifications. ECU remapping is limited but can optimize fuel and ignition curves. Forced induction kits exist but require significant modification. Stock internals handle moderate increases, but guide condition must be verified first.
In a 535i (E39), combined consumption is ~11.5 L/100km (~24 mpg UK). Highway driving yields ~9.0 L/100km (~31 mpg UK), while city use can reach 14.0 L/100km (~20 mpg UK). Real-world figures depend on driving style, but the engine is relatively efficient for a 3.5L V8 of its era.
No. The M62 B35 uses a non-interference design. If the timing chain fails, pistons will not contact valves, preventing catastrophic internal damage. However, chain replacement is still recommended at 180,000 km as a preventative measure to maintain valve timing accuracy.
BMW specifies 5W-30 or 10W-60 oil meeting BMW Longlife-98 spec. Use high-quality synthetic oil and change every 15,000 km or annually. Proper oil selection is critical to protect timing components, especially in pre-1998 engines. Avoid low-detergent or non-synthetic oils.
