I have smalltrailer tent gross weight 750kg well within the max skoda ocatavia 3 Facelift 1.0tsi  1300kg but never towed with a DSG gearbox, so any advice of towing

 

ALSO in the manual it says 40,000 DSG service interval oil change but other info on line says the 1.0tsi  DSG a 2018 Octavia is a sealed unit and doent need servicing,

 

Is my DSG  a dry DQ200 or a wet clutch, how do i tell?

Welcome.

It is a DQ200. 

7 speed twin dry clutch.  That is what is fitted to 1.0, 1.2,1.4 and 1.5 TSI's & 1.6 TDI's with FWD and no more than 250 Nm.

 

There is nothing different towing with a DSG from towing with a manual.

I tow either my garden trailer and my Caravan with a DSG Octy 3 very regularly, you don't need to do anything different
