BMWs are exceptional cars. Besides they’re ongoing popularity since their emergence in the auto industry, BMWs are established in many ways as one of the most reliable, consistent, and high-performing brands out there. However, common problems such as transfer case failure can put a damper on the driving experience, even if it is something that many drivers encounter each year. In this article, we’ll go over what the transfer case does for your BMW, in addition to what you can do to avoid transfer case failure and keep your car functioning optimally.

What is the function and purpose of the transfer case?

Cars that are designed with all-wheel-drive (AWD) or four-wheel drive depend on the transfer case to transport the power that the transmission generates to the appropriate axles of the car. With the help of the drive shafts, this is the main purpose of the transfer case and the reason for its importance in your BMW. In a BMW, keeping all the wheels of the car working smoothly with one another is an essential task – and without the transfer case working properly it can lead to seriously noticeable performance issues that must be addressed right away to restore your BMW and prevent further damage from occurring.

The common symptoms of transfer case failure

Since BMWs are the gold standard in automotive performance and handling, it should be blaringly evident when it’s performance isn’t up to par with what you’re used to. Transfer case failure often exhibits concerning symptoms that can help the driver and their BMW specialist determine what the original cause of the problem is and how to fix it. So, although they’re stressful and annoying to acknowledge, it’s important to be aware of what symptoms indicate transfer case failure:

Fluid Leaks

All cars including BMWs utilize various fluids that perform different functions for the engine and other systems, such as brake and coolant fluids. All fluid leaks are highly concerning, as they usually indicate your car is in need of repair. Transfer case fluid leaks are problematic and must be addressed immediately; if the fluid leaks out of the system, the various components won’t function correctly.

Odd or unusual noises coming from the engine

BMWs engines are relatively quiet, but the noises you do hear should be consistent. If you pick up on any concerning sounds that are not usual for your BMW’s daily performance, such as grinding while shifting gears, you should have it checked out right away – this could indicate a failing transfer case.

Gear-shifting troubles

Transfer case symptoms are often misdiagnosed and attributed to another failing transmission component. It’s important to remember that gear-shifting issues such as hesitation or grinding could mean that your BMW is experiencing multiple issues with the transmission that affect one another. The transfer case components should always be considered when addressing symptoms of transmission or gear-shifting problems.
