I just replaced the camera on an S6 Edge (SM-G925A) with a new unit and it's showing a "Camera failed" error whenever I...

I'm afraid not. I just tried it on the Galaxy S6 Edge and the suction cup doesn't provide enough force to pull the panel off. Instead, I used the heavy-duty suction cups that iFixit recommends and even then it was difficult. After heating up the perimeter of rear panel for 20-30 seoncds, I placed the suction cup near the bottom of the rear glass near the charge port and pulled the suction cup while having a friend slide in an opening pick into the very small gap near the charge port. Leaving that pick in place, I worked my way around the sides of the phone, sliding in more opening picks as I went to prevent the glass from re-adhering to the phone.

Do you mean that you plugged an Apple Lightning cable into your OnePlus One? If that is the case, and the port is indeed damaged, you can buy a replacement port. The port is connected to the motherboard at the top of the phone with a flex cable that runs below the battery a bit of tape. See step 16 on the teardown.

You'll want to take a look at the TSB / SI B 11 08 03. It's a well-known problem for this era of BMW cars including X3 and 5 Series. Here is a copy that I found: http://chrisparente.com/Images/530/CCV-SIB110803.pdf By the time I identified it on my X3, I had already blown a head gasket, but hopefully your X5 will avoid a similar fate.
