Sometimes, there might be something wrong when you push in the clutch pedal or shift gears. Although you may suppose the drivetrain system has problems, you still don’t know what the exact issues are. Here are some ideas to help you to confirm whether the dual mass flywheel is failed or not:

Noise. when the bell housing makes sounds like banging or lots of rattle, you may check your dual mass flywheel

Slipping. When being wear and tear, or cannot meet the demand, the clutch is slipping and you can get a smell like burnt bread with gear oil. Higher gears often have this first, because of increased wind resistance as well as its ratios. If you cannot smell the facings burning up when this is taking place, the dual mass flywheel is slipping and needs to be replaced.

Vibration. When the springs and other internal parts are failed, vibration could often be felt from the floor of the car which directly leads to flywheel’s inability to reduce the tremors. As a result, it should be replaced.

Friction Surface. If there are too much scratches, It's time to replace the dual mass flywheel.

The rotational free play. Move the secondary flywheel to the left, which the pressure plate bolts up to, and mark the gear tooth. Similarly, move the plate to the right and mark that gear tooth. When the left to right play is over 2.54 centimeters, the dual mass flywheel should be replaced.

1. You can replace it with an original dual mass flywheel. But it's easy to be broken once again and it is expensive.

2. You can buy Valeo or other manufacturers' single mass flywheel conversion, it's unlikely to be broken but it is still expensive somtimes.

3. You can contact Zndmotor to get the single mass flywheel conversion with much more competitive price.
