Known Issues
Cooling System Leaks:
Common issues include plastic expansion tank cracking, hose deterioration, and water pump seal failure.
Vanos System:
Early M50 engines (non-VANOS) are simpler. Later M50 variants with VANOS can develop issues with solenoids or the sealing rings, leading to rough idling or loss of low-end torque.
Oil Leaks:
Valve cover gaskets and oil pan gaskets are common sources of leaks over time.
Subframe Mounts:
Rear subframe mounting points can crack or wear, affecting handling and alignment.
Window Regulators:
Plastic components in the window regulator mechanisms can become brittle and fail.
