I have a June 2017 yeti Tsing 1.2 DSG. I AM CURRENTLYING TO CONFIRM THE CORRECT HEAD BEAM AND DIPPED BEAM LIGHTS ARE TWO SINGLE FILIMENT AS THE DIP STAYS ON AND THE HEAD LIGHTS ALSO. 

I.ORDERED BULBS FROM A LEADING SUPPLIER AND HE IS INSTANT THAT THEY ARE TWIN FILIMENT.

REAL CONCERN IS Skoda say the same, yet when oI looked all I can see is single FILIMENT.

Have I lost the Plot??

You are in Eire (used for disambiguation between nation and island). Your vehicle may be a different specification to a UK example.

The pre-facelift uses H4 (twin-filament) lamps but I believe the post-facelift uses individual H7 (single filament) lamps for the dipped and main beam.

Weasley is correct.
Prefacelift = headlight H4, fog light H7
Postfacelift = dipped beam H7, main beam H7, fog light H7.
