Hi all, I would absolutely love some help with my current issue with my beloved z3
Out of nowhere, (cleaning the trunk was the last thing I did) the electrical systems started going haywire:
car when turned on went in anti theft/alarm mode (pulled alarm fuses in order to start the car)
window that previously worked now doesn’t work,
the tail reverse light that worked now doesn’t work, and the other side that didn’t work now works (put new bulb in)
entire dash dials don’t work (all show lowest for rpm, speed, fuel, coolant temp)
I know the sensors are working, through the OBD I can see the coolant temp and also RPM.
anyone have tips or idea how I can start to sort these electrical gremlins out? the window isn’t the worse thing in the world but I really want my dash working. Computer seems to turn on (lights on the dash for ABS and also parking brake)
