German Car Maintenance BMW X6 Rear Differential Failure

A 2021 BMW X6 M with 60,868 miles was brought to Auto Werkstatt’s Federal Way location after the owner reported that the vehicle would no longer go into gear. Technicians inspected the vehicle to determine the cause of the drivability issue and found a serious problem with the rear differential.

During the inspection, technicians determined that the rear differential had locked up and was broken internally. The internal failure prevented the differential from operating properly and was identified as the cause of the vehicle’s inability to go into gear. Based on these findings, Auto Werkstatt recommended replacing the rear differential.

The inspection included diagnostic documentation and photographs of the failed component, allowing the condition of the rear differential to be clearly identified. The findings confirmed that the issue was not simply an electronic or shifting concern, but a mechanical failure within the drivetrain.

Because the rear differential had locked up and sustained internal damage, replacement was recommended to restore proper drivetrain operation. The vehicle was inspected at Auto Werkstatt’s Federal Way location with 60,868 miles on the odometer.

This diagnostic inspection gave the owner a clear explanation for why the BMW X6 M would no longer go into gear. By identifying the internal rear differential failure, Auto Werkstatt was able to determine the appropriate repair and provide a documented path toward restoring the vehicle’s drivetrain function.
