Summary

The 2015 BMW 535d is a generally reliable vehicle, but owners should be aware of potential issues. The most significant concerns revolve around the diesel engine’s emissions system components (EGR cooler, DPF) and the potential for HPFP failure. The ZF 8HP transmission is robust but can experience mechatronic sleeve leaks and valve body issues with age and mileage. Electrical problems, particularly with the iDrive system, are also common. Repair costs can be high due to the complexity of the vehicle and the price of BMW parts. Pre-purchase inspections and a thorough review of the vehicle’s maintenance history are highly recommended.
