I have a 325d but it has the same M57 engine which is why I am writing in this category. Last year my Dual Mass Flywheel failed, it suddenly started making loud noises when clutch was half pressed. So I changed it with an after market LUK flywheel and clutch. Surely the noise is gone, but I noticed that I can still hear it, it's so silent that I have to turn off the ventilation and radio in order to hear it. The noise is so low that it feels like a slight rpm change, but it's still there

Is this normal? Is the DMF suppose to make slight noises or is my new DMF going bad? Here is the vid I took:

Nobody?

Most of us here drive auto diesels. No manual bmw diesel in usa.
On my tdi I had rattle and decided to go smf with vr6 clutch. The dmf had some play but I compared to a new one a friend was installing on his, and it wasn't much difference. Maybe it will quiet down with use. My Smf was louder of course but other than that, I could barely tell a difference.

My rule of thumb on mysterious noises in vehicles with diesel drivetrains is just drive on. Something will let go sooner or later if it's really anything to worry about.

Throw out bearings also make odd noises also.

The engine rpm will pick up by literally about 20rpm when you press the clutch. It masks a vibration which would occur with the clutch pressed. This is totally normal.
