The BMW 740d E38, produced from 1999 to 2001, epitomizes luxury sedans with its elegant design, advanced technology, and unparalleled driving experience. As part of the final production years of the E38 series, these models incorporate essential refinements, delivering a driving experience that balances comfort and performance. For those lucky enough to own one, the 740d offers not just transportation, but a status symbol that transcends age.
Common E38 problems include cooling system failures (radiator, water pump, expansion tank), oil leaks (valve cover gaskets, oil pan gasket), and suspension issues (especially self-leveling suspension). The complex electronics can suffer from faults, leading to issues with the instrument cluster, central locking, and other systems. The pixelation of the instrument cluster display is a well-known issue. Check the condition of the leather upholstery and wood trim, as these can show signs of wear. Be watchful for coolant leaks. Radiator hoses need replacing regularly.
WOF tips
During WOF inspections, carefully examine the suspension components (especially the self-leveling system), brake condition, and lighting functionality. Ensure all seatbelts are in good working order. Rust can be an issue, particularly around the wheel wells and underbody. Pay attention to any warning lights on the dashboard, as they may indicate underlying problems that could lead to a WOF failure. Check for excessive exhaust emissions.
About the BMW 7 740 d
Renowned for its blend of luxury and technology, the E38 740d is powered by its robust inline-six engine that offers both performance and efficiency. However, as these vehicles age, particular attention must be given to common maintenance areas. The cooling system, particularly, should be inspected around the 150,000 km mark, where the water pump, thermostat, and radiator hoses commonly require replacement.
