Quick update in case anyone ends up having the same issue. I ordered a new thermostat for $40 on ebay and replaced it myself. Everything has been working perfectly. So a savings of around $1250. I wasn't surprised the shop was trying to screw me over. I've been keeping an eye on the coolant and oil temperatures with the android "Torque" application and everything is working just as it should.

Glad you got it fixed. A non-operational thermostat is like plugging one section of the system loop.

No I didn't (yet.) I wanted to make sure that the thermostat was the issue before touching anything else. Reading some other threads I'm sure that the tank will need to be replaced soon as well since the stick is missing.

Ok, so I found another small leak coming from the upper radiator hose. At first i thought it was the hose but when I took it off, i saw that the plastic piece that the hose goes around is cracked and just broke off. I caught it before it could go anywhere.
After doing more research, I'm confused. My hose does not look like part number 17127519248 in this link (02)

Basically it only has two ends - one clips into the plastic piece on one side and the other into the radiator on the other side. Does anyone know if they sell only the plastic piece (clamp?) on the left side of the image that the actual hose goes into or what that piece is called? I am having a hard time finding the complete hose that I actually have...

Double check your hose. At first glance my hose appears as though it is only one single hose. If you run your hands underneath the hose plastic ends however you may discover the secondary hoses coming off the plastic ends (sort of hidden by the larger main hose). I have not seen these plastic ends available separately and don't know how you would attache them to the rubber part of the hose in any case.
Our 545is are hitting an age where engine compartment heat seems to have brought the coolant system plastic components to the end of their useful life. Replace all of the hoses that have not been replaced recently in addition to your coolant reservoir so you can sleep like a baby.

I double checked the hose (i took it off when I was replacing the thermostat) and there are no secondary hoses. Thanks for the advice, I'll keep looking for the correct hose.
