2012 Octavia, 1.6 something something greenline. Sadly it's not red, but I'd quite like to get a TdF horn anyway.

It's got the affected EA189 engine. The Euro 5 standard permits about 4 times as much NOx as the EPA standard, so it seems unlikely that they needed to cheat to get your Octavia to be EU legal. If you still want to reduce your NOx emissions, my previous comment applies - driver behaviour has a significant impact, NOx tends to rise with power so avoid high speeds and heavy acceleration.

Age, capacity, induction system? It's only a small number of VW engines which had the defeat device, and they just increased NOx in normal use in exchange for reduced CO2, as the SCR used to reduce NOx to N2 needs energy to drive the reduction, some of which comes from oxidising more carbon and hydrogen, therefore higher fuel consumption and corresponding higher CO2 emission.
There's a lot you can do to reduce your emissions without altering your car; drive less, drive slower, lift and coast. If you happen to have one of the VW engines with the defeat device, there's a good chance they won't be doing anything about it in Europe anyway, EU testing is less stringent on NOx compared with the US EPA, which is why we all drive diesels and very few of them have SCR, only a few high output models which are pre-emptively complying with Euro 6 AFAIK. In the US, they may have to fit bigger AdBlue tanks to allow people to use the SCR more of the time.
