What individual's call a "dual" mass flywheel, BMW calls a "twin" mass flywheel. There has been confusion caused by this because diesels and some modern BMWs use something called a "dual" mass flywheel. The modern dual mass flywheel is actually comprised of more than one part, but the dual mass flywheels found on a 528e or 325e are actually a single piece.

These flywheels just weigh twice as much as the standard flywheel. BMW used these special flywheel to try to smooth out the idle of these models. This is because the idle of the long stroke M20 2.7L motor was considered ruff, and so to smooth it out, the dual mass flywheel was used. Many people have said that these flywheels can cause rattles. This is simply not true. The rattles that most people complain about are actually coming from the throw out or release bearing. This is because the dual mass flywheel uses a completely different throw out bearing which is more prone to rattling. Also many people wonder if you can replace a dual mass flywheel with a single mass. The answer is yes, but you have to use the proper clutch parts. All of the clutch parts for the single mass flywheel are different than the dual mass, so you will need to do a complete clutch job if you want to change the flywheels.
