The 2002 BMW 745i is equipped with BMW’s N62 4.4-liter naturally aspirated V8 engine, producing 325 horsepower and 330 lb-ft of torque. This aluminum-block engine features BMW’s Double-VANOS variable valve timing system, electronic throttle control, and a sophisticated engine management system. The N62 was BMW’s first V8 to use Valvetronic variable valve lift technology, which eliminates the traditional throttle body for improved efficiency and response. This engine is paired with a 6-speed automatic transmission and provides strong acceleration while maintaining reasonable fuel economy for its class. The N62 represents BMW’s transition to more advanced engine technologies in the early 2000s.

The 2002 BMW 745i shares most parts with the E65/E66 7 Series generation spanning 2002-2008. Engine components from the N62 4.4L V8 are compatible across 2002-2005 745i models, with some variations in 2006-2008 models due to minor updates. Body panels, interior components, and suspension parts generally interchange within the entire E65/E66 generation. However, early production 2002 models may have unique components that differ from later years. Electronic modules and iDrive components should be matched by production date and software version. The 750i models from 2006-2008 share some parts but use a different N62TU engine with updated components that may not be directly compatible.

The N62 4.4L V8 in the 2002 BMW 745i has mixed reliability, with significant issues that owners should understand. While the engine provides excellent performance and smooth operation when properly maintained, it’s prone to expensive problems including valve stem seal failure, VANOS system issues, and cooling system problems. Regular maintenance is absolutely critical, including frequent oil changes with BMW-approved synthetic oil and prompt attention to any warning signs. Many reliability issues stem from deferred maintenance or using incorrect fluids. When well-maintained, these engines can provide satisfying performance, but potential owners should budget for higher maintenance costs and be prepared for major repairs around 80,000-120,000 miles.
