My I-drive on my 2004 530 has a mind of its own. It has been posting odd error messages for no reason and changes settings on its own.
with one of my keys, the radio shows the station names (eg JACK FM) on the screen along with the station frequency while the other key only shows the station frequency. I have never found a setting for this on the user interface.
The air conditioning is not working with one of my keys (the one with which the radio works properly...) The fan can be heard to be blowing full tilt but nothing is coming out of the vents. I've turned up all the variables in the climate settings to max but this has no effect. It's almost seems like there's a vent inside the dash which is not opening. With the other key, everything works as it should.
Warning messages about the trunk being open suddenly appearing while driving down the street
Odd messages about there being too much pressure pushing the drivers window up.
I took the car in to the dealer a while ago to complain about this but they couldn't locate any real problem. Anyone else experiencing this sort of sillyness?
