How to Diagnosis a failing DMF?

1 minuteread

Diagnosis of a failing DMF:

Diagnosing a failing dual mass flywheel are often a touch tricky since most of the symptoms could also mean issues with the clutch itself. A definitive assessment will involve visual inspection of all components, but if you have got any of those issues, then your flywheel may be the culprit.



If you hear plenty of rattle or banging sounds from the bell housing, possibly the DMF has failed. These noises are often very loud and it should get replaced as soon as possible.



When a clutch is slipping thanks to wearing or otherwise not being up to the capacity to the demand placed thereon, you get a burning smell like that of burnt bread and equipment oil mixed. This usually happens first within the higher gears because of the upper gear ratios and increased wind resistance. If you are doing NOT smell the facings burning up when this can be happening, it’s your dual-mass flywheel that’s slipping and it must get replaced.



These vibrations can usually be felt on the ground of the car and are thanks to the failure of the springs and other internal components. This leads to the flywheel’s inability to dampen the tremors with use and it must get replaced.

Again, if you have got any of those problems, it is time to visually inspect the clutch and flywheel.
