Are you plugging in a trailer that uses a 7 pin connector or a 7 pin to 4 wire flat?
If the flat 4 wire, only pins 5, 6, 3, and 1 will be in use when the trailer is plugged in. If you reversed pin 6 and 7, then your right turn/brake light will not function.
If wiring is an issue, I would lean more towards the CANbus or fuse box wiring. What happens if you unplug the controller module? Do the weird issues go away? If so, definitely something with the wiring or controller.
If not, I would lean towards a bad controller or something odd in the coding. You can reset the coding through ECU coding I believe. I'm not good enough with that to tell you how to do it off the top of my head, but seem to remember it being pretty straight forward with instructions posted on the coding forum. If you are so inclined, some of the really knowledgeable coders here will review coding if you can pull and email the files.
I've never had PDC put the car into park, so something really weird there. Maybe you have several issues that are unrelated to the hitch. NOT an expert here, but pretty sure that all the communication between the module and vehicle occurs over the CANbus, so would not think that mis-wiring of the 7 pin would cause the issues you are describing. I also would think that if you did not have the CANbus wired in correctly, that Okee could have coded the module. Just thinking out loud here, but if a power wire was out of place, the module may not be fully powered which could cause some weird issues possibly.
If you have the skills, I would verify power at the end opposite of the fuse block for correct voltage.
Really interested to see how this comes out.

Thx for staying on top of my issue. I really appreciate the feed back.
Darly from invisihitch emailed me back on the wire color coded designations:
"One wire is Yellow/blue, and the other is Blue/yellow. In wire color designations, the dominant color is listed first and the stripe color is listed second.
If you are having PDC errors, you don't have a coding issue. Likely a wire or connector was pulled during installation."
So it looks like im good on the round plug wiring (it is a flat 4 prong plug with no surge brakes) but their directions showed to attach all 7 wires to their respective posts.
I made an appt with my local bmw dealer for next tues. I've used a particular tech before that solved an issue I had where two other techs missed it. So I requested him.
One thing that did happen during my wiring install is the two canbus plug wires are very thin and when I went to plug one one side of the connector the wire snapped off, so I had to cut the connector off on both sides of the harness and I soldered them together and then heat shrunk the connection.
I'll note this to the tech because I read in one thread where the owner unplugged the canbus connector and then replugged it back together and the issue he was having was solved. I never tried that since the connection is now soldered.
The tech should not refuse to work on this issue for me because they dont do invisihitch installs there (I would have gladly paid them labor). And the harness and controller box that came from invisihitch is supposed to be bmw OEM.
Here are pics of my canbus repair:
