Well I am very tempted to ask for a refund depending on the reading from diagnostics and I do motorway driving for work so a 1.2 wouldn't last as long as the 1.4. I think that's why my Polo died a bit. I want another one if I do have to shift this one but I'd much rather not.
See what the diagnostics say, if you're lucky it could be a simple fix. It sounds like whatever it is it's better than your Polo
Why wouldn't the 1.2 last as long? Apart from the internal dimensions the 1.4 is the same engine as the 1.2 sporting.
