Need to find a part number of a pipe / hose


A friend of mine went beneath the car and noticed this pipe : A2228321690 that was completely broken and detached. I bought a new OEM one for only 22 USD shipped and will have it replaced by my local mechanic.
This pipe was not the main issue though, the other one (a soft pipe if you call it that way ?) was sliced and was leaking coolant everywhere. He managed to "patch" it and now it does not leak but I'd prefer to replace it.
I'm looking for its part number, I don't know if there's a confidential mercedes pdf that documents all part numbers and their location.
I want to buy it before going to my mechanic so I can change the two broken pipes.
By the way, my car is a 2016 S350d and here's its vin : WDD2221321A255470
Thanks for your help !
If your vehicle was made before 7/2018 you should get the WIS/ASRA from eBay. You will get your part numbers and diagrams with repair procedures.
