I have just learned that my '02 530i with 88k miles has to have the torque converter replaced. The drive has not changed other than the service engine soon light coming on. Am I putting my car at risk for further problems if it is asymptomatic. Has anyone experienced any issue such as this, especially with so few miles relative to the magnitude of the problem? This is my first BMW, and I am a bit taken aback by this type of repair. Any comments/advice would be greatly appreciated.
