In this Steve's Garage video I replace the two heater core hoses and the turbo wastegate actuator hose or line on a MK4 VW 1.8t. The wastegate actuator hose cam bundled with my heater core hoses, so even though it didn't need to be replaced, I did anyway. I suggest replacing both heater core hoses if you're doing this job. If one has failed, the other isn't far behind. As far as the wastegate actuator line, that one is up to you.
This video should work for all 99-05 MK4 VWs with a 1.8t. I believe this also applies to MK1 TTs with a 1.8t I don't have enough experience to know if this applies to the 2.0 or VR6 engines, so please leave a comment if you found this useful for those engines as well!
Because you typically need to drain and refill/bleed the cooling system when doing any sort of replacement on it, it's a good idea to replace as much as you can while you're in there. Because of that fact, I'd check out my other two MK4 1.8t cooling system videos here:

The part number for the heater core hoses and wastegate actuator line I bought is 1J0121156AT. This part is available from a variety of websites such as @fcpeuro or @ecstuning. Please double check fitment before purchasing!
As always with my videos, I'm assuming a certain level of knowledge and experience on your end. I'm not responsible for any damage to your vehicle. Be careful, ask questions if you have any, and have fun! Thanks for watching!
