Atlantean

Thank you very much for this info, it's very much appreciated. I had a suspicion that they were T45 but I was also told T40.

I just got an 18 Octavia Combo 1.0 TSI facelift and I want to do an oil change. Before I go jack it up and crawl in under it can anyone tell me what size the torx screws are that secure the undertray? I'm more concerned about the 3 larger bolts towards the rear of the tray (11 on the attached diagram) as I might not have a torx large enough to undo it. All I can find is that the part number is WHT 000 729 A and that it's M8x20. TIA
