No, what your feeling is the torsional vibrations within the crankshaft. You can get away with removing a DMF on a petrol car as they are mainly for refinement. On a diesel they are for refinement but also crank durability for higher power diesels, as the peak cylinder pressure are very very high. The Dual Mass lowers the overall stress in the crank.


There is no way to solve your problem appart from refitting the DMF as it was designed to be. Also don't be surprised if your crank gives up the ghost in 10k miles. DMF's aren't for fun, they don't spend a small fortune having them designed and signed off becuase they like to charge you lots when you need to replace them.
