turbo coolant supply line leaking, anyone replaced one?

So I noticed some coolant leaking from my rear turbo, I assume the o-ring is failing.

Has anyone replaced the coolant line? looks like it might be a PITA to get the the torx screws, Should I expect to dump all the coolant when I disconnect the line?

I havent noticed any change in coolant level

I had both turbo coolant line leaking. The dealer charged about 7k to fix for about a 6-8 hour job. Luckily I had an extended warranty. The car had 74k miles 2016. I am the second owner since 2018. Good luck
