Who knows but it's worth trying every avenue in order to save money......

Looks like you only disconnected the sensor, however you can bypass the sensor to test if it's the sensor or the wiring (maybe a short).
You can bridge the terminals from the harness to manually switch the rev. lights on and off and this checks the wiring.
I've attached a picture for a Honda and instructions (hopefully you can follow) having the same issue.
Since you are driving an MT, there is an easy way to test the switch.
Yes the key has to be on (engine off), otherwise the lights would still be on when u leave it parked in rev. gear and take the key out and walk away....
Put it in neutral and turn the key to "on"...your rev. lights will be on, if ur having the problem you described,
Now unplug the sensor from harness. The lights should no longer be on. You can
bridge the terminals (SEE PICTURE-Hopefully a similar 2 wire setup for the X5) from the harness to manually switch the rev. lights on and off and this checks the wiring. If they didn't turn off at all, make absolutly sure u unplugged the right thing and then you can check the wiring.
QUESTION: Just to be clear, when you unplugged the sensor did the lights stay on? If they did then you are dealing with a "short".
