Im getting P0522/P0523 and U0184. Looks like I may be getting it towed to the dealer.

P0522 /P0523 are low and high oil pressure readings, respectively.
Hunt down your oil pressure sensor and check for damage or wiring issues.
U0184 is lost connection with boom audio. Could be low battery caused it or I read someplace that the BCM (body control module) could be at fault.

Having to take it 200 miles sucks but might be your best bet.
Good luck.

my understanding anything lower than 12.7 indicates weak bat. but that may not be the whole problem. good luck.

A weak battery can cause all kinds of codes. I'd start there.

My owners manual for my 2013 RGU states 12.6V is only 75% charged. Refer back to your manual and check if it isn't in transport mode.

That was me I'd get a new battery and I'd make sure it's not in transport mode.

Although the battery does not seem fully charged, if it cranks...there should be enough juice for it to start.

So...seems to me unfortunately it needs a trip to the dealer.

Another vote for the battery. It was most likely not put in transportation mode and sat in a container with the lights flashing till the battery died.

My friends SG wasn’t having any issues at all until we were set to ride one day. Bike turned on fine, all electrical worked, turned over with no hesitation but it wouldn’t fire. No codes, no issues that we could find. Went to a local oil supply store that’s also a Deka battery dealer to get a new battery as his was 6 years old. Bike fired right up and off we went.

That's not my experience, although admittedly with an EFI BMW. Darned thing would crank over just fine, but the max voltage the battery could deliver when fully charged had dropped from optimum and the fuel injection wouldn't kick in. The battery was around 11/12 years old, so a new replacement was an easy decision, after which the bike ran like a champ.
