Dual Mass Flywheel Failure on Audi A4 Quattro

The flywheel for the 2006-2008 Audi A4 Quattro with the 2.0 FSI Turbo engine is a non-conventional "Dual Mass" flywheel. It is known to make light rattling noise when the engine is cold, and should subside once the engine temperature raises. If the rattle doesn't go away when the engine warms, the flywheel may have failed.

If the dual mass flywheel has failed, the only solution is to replace the flywheel.
