Summary

The 2004 BMW 530i, while a desirable car for its driving dynamics, can present a number of reliability issues as it ages. Engine oil leaks and cooling system problems are common and can lead to costly repairs if neglected. Electrical issues, particularly with the iDrive system and battery drain, can be frustrating. Suspension components, like control arm bushings, are also prone to wear. The 6-speed automatic transmission has its own set of potential issues with the valve body. Depending on the severity, the costs to repair these issues can range from a few hundred dollars to several thousand.
