Does anyone know what the difference is between a Octavia mk3 SE L petrol DSG  .    (1.5 TS i,  PS)    and a     (1.5  TS i GPF ACT  ) ?  They appear to be the same  car although one is 69 plate ,the other  On a 20 plate.

They are 1.5 TSI ACT and 150 ps.   That will be both of them. 

The 20 plate has a GFP, the 19 plate doesn't.

@PetrolDave  Did they really not fit the GPF in time for the introduction of the WLTP and not till 2020? 

My bad,

I thought that was very much what the co-ck up in 2018 was with the new engine management and the Kangerooing issue and issues and now more recent issues / cutting out.
