When I am just idling, sometimes the engine just revs on its own and the rpms bounce up and down. Usually after a bit the car just shuts off on it's own.

Experiencing a woofing noise when idling. Thought it was exhaust flap...again however it has been diagnosed as the duel mass flywheel. The flywheel is said to be failing and is a known issue that has been fixed in newer versions of the flywheel. The car is off warranty and this repair for a known issue is quoted to cost us in excess of $2000.00. I can't remember the last time I purchased a flywheel, this seems ridiculous.
