Identify part - help

Hi, Looking for help identifying coolant hose part for 2014 GL450... dealer closed today and not finding any luck with google searches... I'll attach picture if I can, numbers printed on hoses are A2115010125-Q7-PA12. Looks like will need the connector end, and not sure I'll get the broken off piece out of the hose, so the hose as well.

Thanks for any help, car is parked awaiting repair and not looking forward to towing to dealer to replace an 8 inch or so section of hose.

Is it possible it is this and the short section I was looking at is because of a previous splice/repair...

Looks fairly straightforward either way, just want to make sure I get the right part.

The 211 501 01 25 part number comes back as Engine Coolant Recovery Tank Hose or Coolant Breather Pipe.
Amazon has it for $12, which includes the connectors.

Pretty sure your hose has been repaired at some point. Those plastic hoses become really brittle and break with the slightest touch. I leaned on mine while checking something and it snapped of in the same place as yours. Just pull up the metal S-clip and you can easily pull out the broken end of the hose. That S-clip locks it into place. I believe the part you need is #11 in the diagram below. 166-500-10-91 is the part number. It also connects to the radiator and the overflow reservior. Careful removing it from the resevior as that can snap off easily as well, Easy fix though just be careful with all the plastic parts as they get brittle with time. I believe FCP Euro has the hoses or just go to the dealer and pick one up as i can almost guarantee they have it in stock. Should be $80-100

Thanks all, it does appear someone did a splice repair at some point, the part number that's on it comes back as compatible with 2009-era GL. I'll be ordering the part ID'd here tonight.
