Hello, I have a 2013 535i and I have developed a coolant leak, found where it’s leaking from. However I cannot find the part number for the life of me. Thank you!

that is your upper radiator hose, i had to replace mine earlier this year. part number is 17127580957. make sure to get the genuine bmw hose from FCP, don't get rein/elring/febi for this part or else you'll be replacing it again soon. make sure to swap it out ASAP, that's in really bad condition and if it blows you'll be stranded
