Engine Performance
The 540i xDrive features a 3.0-liter turbocharged inline-six engine that delivers impressive power and efficiency.

While the suspension is generally reliable, some owners have experienced premature wear on components like bushings and control arms, especially if the vehicle is driven aggressively. Keeping an eye on suspension components and addressing any signs of wear can help maintain optimal performance.
Other Key Components
When it comes to other critical systems, the 540i xDrive is equipped with advanced technology, including a sophisticated infotainment system and various driver-assistance features. While these systems enhance the driving experience, they can also be a source of frustration if they malfunction.
