I realize this COULD be a coincidence but how likely is that? My understanding is that the vanos affects timing so even if only the bolts were changed, could something else have been disturbed in the process? Not sure what to do if this software update doesnt fix the problem.

Hey, did the software update fix this? My cold starts are not as bad as yours but definitely worse since this recall. Thanks
