Doesn't brown sludge in the coolant point to maybe another issue? Like how did the contaminant get there?

Your heating problems sound like a stuck open thermostat.
you've stuck with the skoda dealer then, or had a second quote/analysis ?
read a thread which still didn't tell me what the curious silica gel bag might do Golf mk7 tdi heater blowing cold
Noticed my coolant is an orangy brown colour, so looks like that needs changing aswell. Mine says it has got one of them silicone bags in the reservoir. It is supposed to help stop corrosion, hopefully it hasn't split.
Usually you will have a couple of small hoses going in/out of the engine compartment firewall, these are the feed/return pipes to the heater matrix behind the dash and both pipes should be (very, may burn your skin) hot to the touch when the car is at operating temperature. Often there is a thermostatic bypass value that shuts this part of the cooling system off so that the engine warms up faster, they can fail which seals off the heater matrix from ever receiving hot coolant.
I'm not familiar with Octavias but it should be easy to get to i.e under the bonnet. I'd imagine it's a shared component being a vag group vehicle so hopefully not too expensive? It may even be part of the thermostat housing.Is it a big job to get to and replace?
