Hi All My car has a failing Dual Mass Flywheel, and my mechanic has said it needs replacing badly (just had a full service). I have only owned the car for 7 months, and is under warranty - the DMF is covered fortunately. However, they will only replace it when it fails. When it fails, will it cause damage to other components? What should I expect when it fails? The car does sound rough, even more so now it's colder. What do you think?
