Remove the iDrive display and disconnect the purple connector.
Look at the connector on the display, are all 10 pins straight?
Look at the connector on the cable, metal contacts should be visible in 8 of the holes (pins 3 and 8 in the center are empty).
If the display connector is OK, it is likely that one of the pins on the cable is loose in the connector. Partially remove the metal shield, and the contacts will be visible. Use a very small screwdriver to reposition the displaced contact.
