Which engine?

[royzee5787]

Hi
Hope someone can help. I just bought a 2015 Astra J sport tourer.
I am a little confused. Easily done, I know!
On the documentation it says it is the A17DTS opt. LUE engine.
BUT, if I use a decoder for the vin it tells me its a A17DTC
So, my questions are
Which is it and what does the opt.LUE mean? I can find any reference to that.
Many thanks in advance for any help
