That's what I thought my problem was too... Either a glow plug or the control unit.
Anyway, I'm removing my swirl flaps in the next few days. Shouldn't cost me more than £50 for the job and it's the only guarantee that it won't happen again.
Just for the record, it's a European 2009 E90 LCI 330d Steptronic.
My 330d is still ever so slightly unsteady at cold start and ONLY stone cold start for 30 seconds or so, until it is revved.
Mine is also a 2009 but a 6MT. 80k miles on it now.
