Is the restrictor necessary? Can I just cut it out?

System will still work without the restrictor, it is really to bleed air. But when it plugs, air won't purge and the system can overheat.
When the restrictor is removed, slightly more coolant is diverted away from the radiator to the tank. No biggie.
You can use any coolant in a 1.6.

I just tackled this over heating problem. My restrictor was completely plugged. Had to drill it out. Also added straight water and rad flush and took it for a test drive. Engine was running at 195 and 200 if I stomped on it. Never over heated and the whole rad is warm again. Going to test the old thermostat tonight. Just waiting for the car to cool down to fill with proper coolant

i dont happen to agree; that doesnt mean it will be a problem; vw coolant runs $28 or so.

i run straight water thru 2X after flush, (fully warming up both times). after a flush you now are safe to use red vw coolant(if you already havent used).

So, a t-stat change and restrictor fix. Not too painful.
(WP change can be a project.)
Refill with coolant of choice, but don't mix the spendy stuff with cheap. Bad mojo.

Water pump still looks good. Has gold thick fins. Took it out for another test drive and so far so good.
Real test will be Monday.

dont use the cheap-o
.so after clearing you dont have much residue in the flush/mix?
replacing wp means timing work

The old thermostat tested fine so it looks like it was the restrictor. When I flushed the system a lot of scale came out

perhaps flush again; you can drive it like 50 miles max and of course drop (water) when warm
just dont drive so far away if something does happen

Sounds like you have it solved. One thing that wasn't mentioned - you may want to either have the radiator rebuilt or replaced. Don't know how old your vehicle is but over time they fill up with crud and loose efficiency. The "lot of scale" is a clue to a plugged radiator.

I'm planning on swapping the 1.6td this summer. I'll make sure it gets a new rad at that time

It wasn't moving then in 5 minutes just started coming out the reservoir.
That didn't answer my question.
Could still be just a clogged line.
