after a vcds scan i got this fault code on 47 soundsystem:

1 Fault Found:
1559 - Cooling Fan for Housing 
          B126B 01 [008] - Electrical Failure
          Intermittent - Confirmed - Tested Since Memory Clear
             Freeze Frame:

enyone know what this is and if this can be related to the infotaiment freeze and strange behaviour on cold days..

I think it is the fan that cools the infotainment unit, sometime it is not working
