2000 BMW 740i

Introduction: The 2000 BMW 740i is a luxury sedan that offers a smooth ride and impressive performance. It is powered by a 4.4L V8 engine that produces 282 horsepower and 324 lb-ft of torque. The 740i comes with either a 5-speed automatic or a 6-speed manual transmission. People like the 740i for its spacious interior, comfortable seats, and powerful engine. However, some common issues have been reported with this vehicle.

Engine

4.4L V8

• VANOS system failure: The VANOS system controls the timing of the engine’s valves. If it fails, the engine may lose power or stall. Replacement of the VANOS system is necessary, which costs around $1,500 - $2,000+.
• Intake manifold gasket leak: The intake manifold gasket can leak, causing vacuum leaks and a decrease in engine performance. Replacing the intake manifold gasket costs approximately $300-$500.
• Timing chain tensioner failure: The timing chain tensioner can fail, causing the timing chain to jump or break. This can lead to catastrophic engine damage. Replacing the timing chain tensioner costs around $1,000 - $1,500+.
• Crankshaft position sensor failure: The crankshaft position sensor tells the engine’s computer when to fire the spark plugs. If it fails, the engine may misfire or stall. Replacing the crankshaft position sensor costs about $200-$300.
• Valve cover gasket leak: The valve cover gasket can leak, causing oil leaks and a decrease in engine performance. Replacing the valve cover gasket costs approximately $200-$300.

Transmission

5-speed automatic

• Transmission slipping: The transmission may slip when shifting gears, causing a loss of power or acceleration. Repairing the transmission by replacing worn components or rebuilding the transmission can cost around $1,500 - $3,000+.

6-speed manual

• Clutch failure: The clutch may wear out over time, causing difficulty shifting gears or slipping. Replacing the clutch costs approximately $800 - $1,200.
• Gear synchronization issues: The gear synchronization system may fail, making it difficult or impossible to shift gears. Repairing the gear synchronization system costs around $500 - $1,000.

Suspension

• Strut mount failure: The strut mounts can wear out over time, causing a clunking noise when driving over bumps. Replacing the strut mounts costs approximately $400 - $600.
• Control arm bushing failure: The control arm bushings can wear out over time, causing a clunking noise when driving over bumps. Replacing the control arm bushings costs around $200-$400.
• Rear differential mount failure: The rear differential mount can wear out over time, causing a clunking noise when driving over bumps. Replacing the rear differential mount costs approximately $300 - $500.

Electrical

• Alternator failure: The alternator can fail, causing the battery to discharge and the vehicle to stall. Replacing the alternator costs approximately $500 - $700.
• Battery failure: The battery can fail over time, causing the vehicle to not start. Replacing the battery costs around $200-$300.
• Starter failure: The starter can fail, causing the vehicle to not start. Replacing the starter costs approximately $300 - $500.

Exterior

• Headlight condensation: Condensation may form inside the headlights, causing reduced visibility at night. New headlights will need to be installed at a cost of approximately $500 - $700 per headlight.

Interior

• Climate control failure: The climate control system may fail, causing the vehicle’s interior to become too hot or too cold. Repairing the climate control system can cost around $500 - $1,000.
• Navigation system failure: The navigation system may fail, causing the vehicle to not be able to provide directions. Repairing the navigation system costs approximately $500 - $1,000.
• Sunroof failure: The sunroof may fail, causing it to leak or not open or close properly. Repairing the sunroof costs around $500 - $1,000.

Summary: The 2000 BMW 740i is a reliable vehicle but it is not without its issues. Some of the most common problems include engine leaks, transmission slipping, suspension noise, electrical failures, headlight condensation, and interior component failures. The severity and cost of these issues vary, but some can be quite expensive to repair. Overall, the 740i is a well-built vehicle, but it is important to be aware of the potential problems that it may experience.
