Assuming you also have the connect kit, there's a wire going to it that expects 5v and is getting 12v (or vice versa!)

Here's what fixed it for me: http://www.n54tech.com/forums/showthread.php?t=43267

Switched the wires, all codes went away instantly.
Thanks for that, I made a post at that thread. I had my connect kit spliced into the JB4 red wire with the fuse. Can't believe I've been driving with it like this throwing CEL's and codes for a while.

Maybe this will explain the strange electrical noise I randomly get that seems related to the CANflap and/or wastegate position.
