Vanos System:
The Double VANOS system can develop issues with the solenoid seals and O-rings, leading to rough idle, poor low-end torque, and stalling.
Cooling System:
Plastic coolant expansion tanks can become brittle and crack; water pump impeller failure can occur.
Subframe Mounts:
Rear subframe mounting points can crack due to stress, requiring reinforcement.
Oil Pan Gasket:
