Need some help with Codes, car won't start.

Car was running a little rough after filling up.
There was some slight hum from the passenger front wheel area and I just had some tires flipped on the fronts.
Just did a track day a week ago without any issues.
I have a tube and primary catless X-pipe with secondaries in place.
It's a 2011 with 60,000 miles.
Thew the half engine light last night, DSC and Brake light and drove like crap. Now it won't start after a short crank. Charging the battery now but just charged it 2 days ago since my commute is pretty short.
I think I have some exhaust leak from up front because I can smell exhaust fumes with the windows cracked open 2 inches.
I scanned it the next day and a lot more codes popped up including misfires on all 8 cylinders.
Cleared them and was able to drive it to the shop.

Would appreciate any ideas/help.
Thanks!

I'm pretty sure the "additional water pump" is what I had as well but would need see if I find the code somewhere.
This is a black plastic pump located on the driver side on the wheel housing, somewhere below the low pressure fuel sensor opposite of the ignition coils, this pump is for the "rest" function where you can heat the cars interior after a drive whit the engine turne off. I bought a used pump on eBay for about $12-20 and installed it, code gone. Never used the rest function.

Thanks for that. Not sure why BMW needs such a devise.
So it can break and charge us for fixing something no one uses.

Added 2 more images of codes that popped up a couple days later.
So far, tightening the head to X-pipe connection seems to be the fix. Will report back if they come back.
