Morning DW

Welcome to the Forum

I would think that there would be a difference in static balance between a 4 and a 6  your engine is 4 cylinder M47N or N2. Also the crank spigot for mounting the flywheel to the crank may be different.

realoem shows 3 part numbers for your car 565745, 518897, 515192 

Hope this helps

i was told by someone they put a 320d flywheel on a 330d but i didnt see it myself its a shame i cant get 2 used ones side by side with some calipers

The problem is the Refurbishment market buys everything that comes onto the market from the garages so you dont see them in the scrap bin any more.

Try checking TIS in INPA if you have it for the crank shaft Boss sizes see if they are different. If the 3.0 and 2.0 crank shafts are the same Boss size I believe they both have an 8 bolt mounting so it may give more scope. The 3.0ltr DMF will be heavier though so that may have an effect on the 2.0ltr engine.

If my memory serves a company called Scheaffler designed the first DMF's in the late 70's early 80's maybe look for them
