Process to flush coolant?

[pontiff]

My car has cracked the 100k mark so I am doing a major service on it (oil, filter, fuel filter, pollen filter, brake fluid flush, clutch flush and coolant flush)

The ELSAWIN procedure to change the coolant is to undo the radiator hoses and then using VAS, set the car to coolant filling mode (or words to that effect). I have filled up the expansion bottle with what I think is less coolant than i drained so i am wondering what this coolant fill mode is and VAGCOM does not make reference to it.

Has anyone has a similar experience? I'll just keep an eye on the coolant level in the expansion bottle and top up as necessary but still curious as dropping 2 litres and filling up with 1 doesn't go

I do t believe there's anything fancy on these.

The procedure is pretty straightforward. Dump the coolant, flush, and refill pretty much.
