Lower heater core hose/tube leaking above passenger drive axle....

[tdidieselbobny]

Noticed coolant bottle getting low, so did some looking around. Found a metal pipe that goes to that auxillary water pump on bottom, has a T at top and goes to another hose. Line is above the passenger axle shaft, and has a bracket with bolt and another place it bolts. Looks like pipe is leaking at the welds by bracket. Someone gave me part # 04L-121-065BH. Looked that # up and new # is 04L-121-065CR( pipe looks like what is on car now). Tried ordering it from online VW dealer with my VIN#, and they wrote back and said that part# doesn't go to my VIN, part # 04L-121-065AJ is correct, but that # is for a '15 Passat and looks nothing like pipe on my car. Is there any way to patch line temporarily? I'm not familiar with bleeding coolant on the '15's and have read that it's a PITA, so not sure it's something I wanna mess with, would do it when I get TB done eventually. Don't think it's a bad leak right now, but not sure if it has any pressure. Anyone have any tips?

Hey I know this is an older post, I am looking for this part as well. I know by now you've probably got it solved but I wanted to post that up here in Ontario the part number 04L121065CR does show up in VW parts system and it is the exact part for my car 2015 golf base model. Unfortunately it is discontinued?? ECS tuning has this part available and I'm on the hunt for it. If you happen to read this maybe you can let me know what you did for the repair?
