2011 BMW 550i F10 with VIN C785210 came to the shop, car was in lime home mode.
Scanned with ISTA and over 50 errors, missing DSC module and some FlexRay controller signaling fault.
Checked the fuses, fuse F2 5A blown, replaced blown fuse and all faults were gone.
Drove the car for 15 min everything was fine, scanned it again to make sure all are fine only one fault code:
1C3204 Engine oil pressure switch, open circuit or switch sticking.
I parked the car on side. Car was parked nobody was touching it.
Around 2x hours later I heard the sound same as when you open a door, then i turned the ignition on and all light were on again and same errors, F2 fuse blown.
What can cause this fuse to blown?
