Engine and Performance Problems
The heart of the 730i is its inline-six engine, which is generally reliable but not without its quirks. Here are some common engine-related issues:
- Oil Leaks: Over time, seals and gaskets can wear out, leading to oil leaks. Regularly checking oil levels and inspecting for leaks can help catch this early.
- Cooling System Failures: The cooling system is critical for engine health. Common issues include radiator leaks and water pump failures. Regular coolant changes and inspections are essential.
- Ignition System Problems: Issues with spark plugs and ignition coils can lead to misfires and poor performance. Replacing these components as part of routine maintenance is advisable.
Transmission Troubles
The automatic transmission in the 730i is generally robust, but it can develop problems, especially in older models. Key issues include:
- Slipping Gears: This can occur due to worn clutch plates or low transmission fluid. Regular fluid checks and changes can help mitigate this issue.
- Delayed Engagement: A delay when shifting from park to drive can indicate a problem with the transmission fluid or internal components.
Electrical System Failures
As with many vehicles from the late ’80s and early ’90s, the BMW 730i E32 can suffer from electrical gremlins. Common problems include:
- Faulty Sensors: Various sensors can fail, leading to issues with fuel efficiency and engine performance. Regular diagnostics can help identify these problems early.
- Power Window Malfunctions: The power windows may become sluggish or stop working altogether, often due to faulty switches or motors.
- Dashboard Warning Lights: Warning lights can illuminate for various reasons, and it’s crucial to diagnose the underlying issue promptly.
Suspension and Steering Issues
The suspension system of the 730i is designed for comfort, but it can wear out over time. Here are some common suspension-related problems:
- Worn Bushings: Rubber bushings can degrade, leading to a rough ride and poor handling. Regular inspections can help catch this before it becomes a significant issue.
- Leaking Shock Absorbers: If the shocks are leaking, it can affect ride quality and handling. Replacing them is necessary for maintaining performance.
Summary of Common Problems
