1 Series 120d Msport software update, a day to complete ?

[PaulCW]

Hi I have a 120d mSport from 2009, have taken to registered BMW dealer for a Air intake manifold, ok not cheap, 4 days so far waiting for part so say, they are now doing a software update, 5 hours so far , I am informed that the 120d can sometimes take a day to complete the full update, I find this unbelievable, I am told this is a common occourance on the older 120d's ?
I have had mercs and other cars that have had software updates at a couple of hours max.
But the X bmw Mech said on this model there ar so many componets that have to be updated ??
Really??

I have no experience with this platform (you're posting in the 1M sub-section of this mostly American forum, where 120d was never sold), but if BMW revised coding for several modules and the tech has to go in and reprogram all of them; it wouldn't surprise me if they listed it at 6-8 hours of labor, especially if they require road test to confirm.
