Would be great to get owner opinions about AdBlue in Octavia - diesel, of course. I'm located in very northern Sweden so winter temperatures are definitely harsh! From what year does Octavia have AdBlue?

Mine has AdBlue, I think it came with the Mk4, my older Mk3 facelift didn't have it. I have had no issues at all with it, filled it up a couple of times no problems so far. Range is very good when full, especially if you do reasonably long journeys, where it uses very little. 

According to the manual, Octavia has an adblue preheater, so you should not worry too much about it. If it is sold in your climate then it should work in that climate, but best is to consult the dealership what are their advices and guidelines. 

 

I would personally ask about safe filling levels. I don't know how much adblue can expand while being frozen, so one thing to keep in mind, that maybe keeping it's tank full might not be the best idea. Also driving until the low limit of adblue might be dangerous, as less adblue will potentially freeze faster. 

 

One advice from me - if you are refilling inside a garage or on the floor that you can't easily clean, then use smaller bottles. I once purchased 10l canister, the funnel was terrible, canister was heavy and I spilled a lot in my parking spot in the garage. When it crystallized, it created very slippery and ugly surface.

Thank you guys for your experiences! I'm generally kinda wary about AdBlue since even Volvo - and they should know a bit about the Nordic climate - has had big trouble, at least in V60 (even though the AdBlue tank is heated, of course). Guess I just have to accept that all modern diesel cars come with AdBlue; great that Skoda seems to be doing ok.
