Can you have a look at your undertray?

I can confirm my FL Octavia TSI DSG RS has a full tray with said ducts.

My Octy vRS TDI - you guessed it - the big one. Its a Major Payne!

Mysticality - I assume you mean for oil changes?

My filter is on the top of the engine & I might put in a cut-out to make oil changes easier for my mech.

OTOH, there are only 3 bolts extra on the full tray & it's a good thing to take the tray off to see any visible signs of fluid leaks.
