Help! Have coolant leak and need advice!!

First I have a 2014 Mini Cooper S AWD 6-spd -- not sure what a 3rd Gen is (!) but hopefully I'm in the right place. I've got a coolant leak in the front of the motor and I'm hoping it will look familiar to someone who can give me a best guess at what is leaking? Photos attached. It may be hard to see, but it's coming down directly above the exhaust sensor, working it's way down to the exhaust itself eventually. I saw it on the garage floor and it continued to drip for a while to form a small puddle after about 30 min. I can't really get in there to see well enough to diagnose; so I can't really judge whether this is do-able for me (been working on cars for 45 years) or better to give to the dealer. Hoping for some input here from those with more experience to aid my decision! thanks very much. john p

She's a 3rd gen..

my best guess is a leaking thermostat gasket

Have you checked all the pipes for damage?

Are all the pipe Hose clamps tight?

everything visible without taking anything apart is dry and OK. It must be right in close to the block. which sounds like the thermostat. Is this a DIY? Do they hit you hard for this?
