I never knew until I started Maserati, or certainly Ghibli ownership the amazing number of issues that can be cured through disconnecting and reconnecting the battery. Even the quick release on the battery terminal seems designed to make to aid the process. The only thing following reconnection you have to reset the electronic parking brake, and as I have the power boot lid manually open and close it to reset that function. Everything else including the clock sorts itself out!
Just today the factory WiFi hub my car has went on the blink again, and sure enough the above process sorted it. To date an occasional issue with the Bowers Wilkins Amp not working, erroneous error messages from a low battery, and even the sluggish outside temperature sensor all get cured with this process.
I am thinking a reset button should be installed!
