To change the oil filter on a 2017 2.0 TDI am I correct that it can only be accessed from underneath, and the underbody tray has to be removed?
Yes ....... Here you go, my 'walk through' from when i did my oil change with photo's: https://www.audi-sport.net/xf/threads/diy-oil-change-a3-8v-2-0-tdi-150ps-vag-ea228-engine.317244/ I also did one for the fuel filter: https://www.audi-sport.net/xf/threads/diy-fuel-filter-a3-8v-2-0-tdi-150ps-vag-ea228-engine.317248/
