I own Vectra C 1.8 2002 and i have this problem :

when temperatures are low (autumn and winter) from the steering wheel coming very annoying noise and after 10 minutes driving will stop.
From my near service told me that the problem comes from the CIM and i should replace it. But i have read some posts and somewhere found that this sound comes from the steering colume and should apply a grease paste.

I post link on youtube where you can here this noise.
