Hi, Can anyone tell me if you can by expansion bottle without the mit silikat package that fits directly on my Skoda Octavia vrs 245 challenge edition 2.0 TSI petrol Hatchback 2018 model.

Ask Skoda Dealship today when they had my car in to check it and said they couldn't find it, it looks like it been took out, but also said to me it is very difficult to see with the coolant tank being double skinned. 

Advised me to go on the forums for advice and ask what expansion bottle without the mit silikat  bottle that fits directly on my car?

Let me know part number and where can l get this from?

In '2021 installed 5Q0121407M bottle for my Octy3 '2016 TDI. Version without silicate bag.
Plenty of much cheaper good alternatives in shops- but should check them twice because web pictures for this item often are just for illustration purposes.

And this is true that for newer Octy3 you can't even see this bag or take it out (it's built-in behind wall = double skinned). For early Octy3 it could be taken out with long pliers.

Also can check there: 5Q0121407M | search for Škoda spare parts

I suppose, newer ID now is 5Q0121407AA
