So over the weekend I took my car to car audio install shop to get a subwoofer installed in the trunk. I bought all the parts based on research on different BMW forums and was planning. 3 hours into the install when the shop was putting the car back together they called me to stop by.
When I started the car Idrive showed a Cruise Control Malfunction message.
Also the windshield wiper was on and could not turn it off. Also, no turn signal function or control of the head unit.
The music was still on but could not change the volume. Idrive screen still working fine and I can change between XM radio and CD player...
I disconnected the negative on the battery for an hour but no luck.
Still same message and the wiper is on non stop.
Any ideas?

Ever figure out what this was?
