S3 Coolant leak

[LD3]

When facing the car it's the right hand side one of the pipes going into the engine. Header tank empty looks like a loose clip or something on the pipe is busted. Anyone know how much this would cost. Perfect time of year

Any advice appreciated

Thanks

Oh the other thing was I need to do a 75 mile trip back home and hoping I could fill with water and G12 back to local garage?
