Common Issues with the BMW 520i E39
The BMW 520i E39, while celebrated for its performance and luxury, is not without its share of problems. Understanding these issues can help current and prospective owners navigate the potential pitfalls of ownership. Below are some of the most frequently reported problems associated with this model.
Engine Problems
One of the most significant concerns for the BMW 520i E39 revolves around its engine. While the inline-four engine is generally reliable, certain issues can arise:
- Oil Leaks: Over time, seals and gaskets can wear out, leading to oil leaks. This is particularly common around the valve cover and oil pan.
- Cooling System Failures: The cooling system is critical for engine longevity. Components such as the water pump and thermostat can fail, leading to overheating.
- Vanos System Issues: The variable valve timing system (VANOS) can develop problems, resulting in a loss of power and efficiency.
Transmission Troubles
The transmission in the E39 can also present challenges:
- Slipping Gears: Some owners report issues with the transmission slipping out of gear, which can be indicative of low fluid levels or internal wear.
- Rough Shifting: A common complaint is rough or delayed shifting, which can be caused by a failing transmission control module.
Electrical System Glitches
As with many vehicles of its era, the BMW 520i E39 can experience electrical issues:
- Battery Drain: Some owners have reported that the battery drains unexpectedly, often due to faulty wiring or parasitic draws.
- Malfunctioning Sensors: Various sensors, including those for the ABS and traction control, can fail, leading to warning lights on the dashboard.
Suspension and Steering Concerns
The suspension system is another area where problems can arise:
- Worn Bushings: Over time, the rubber bushings in the suspension can wear out, resulting in a less stable ride and increased road noise.
- Steering Rack Issues: Some owners have reported problems with the steering rack, which can lead to a loss of steering feel and responsiveness.
Interior and Comfort Features
While the interior of the BMW 520i E39 is generally well-regarded, there are some common complaints:
- Leather Wear: The leather seats can show signs of wear and cracking, especially if not properly maintained.
- Electrical Window Failures: Power windows may fail due to faulty switches or motors, which can be frustrating for owners.
