Repairing a BMW Z4, jumpstarted the car plenty of times, everything always worked. Jumpstarted it yesterday and the windows don't work, radio and sat nav screen,roof and indicator on the dash doesn't work. Had it plugged in and it said open circuit, wouldn't communicate. The heated seats DO work. None of the fuses were blown as well, including the main one in the boot and every fuse under the dash.

Any suggestions? Replaced the battery still not fixed it.
 
It doesn't seem to be transport mode, any suggestions anybody, it may have something to do with k-bus I have read around somewhere?
 
Do you have access to a code reader or INPA/NCS? You'd get the fault codes which should point you in the right direction.
 
Had a new ignition switch fitted as advised by my dads friend, it has fixed it for now!

Also on another note I make sure I keep the car under a cover and cleaned all drain plugs out
