The 340i has one of the latest designs of DMF with pendulum absorbers.
I'm wondering when you feather the clutch bite against the anti-stall function, you get a bit of 'chatter' from the DMF due to the low rpm. Maybe this will prove to be a characteristic of this type of DMF.

That thought has occurred to me too.

So I came to a light yesterday (ASS always off, I hate it) and forgot I had my car in 3rd and it slowly sputtered and turned off. As soon as I realized what was happening, I instantly mashed the clutch in and although the engine had already turned off, the car restarted, crank and all, but started in ECOPRO mode, which I never drive in either.

There was absolutely some sort of intervention done considering it went as far as restarting my car. Kinda cool.
