Can anyone tell me where to find the oil filter on my 2015 Octavia.

What you got TSI or TDI ??

Sorry , it's a 20lt tdi elegance.

the oil filter is at the front of the engine looking from the front of the car at the bottom right and you get to it from underneath you need to remove the bottom cover and it at the front bottom right of the engine see pic 

Thanks for that very helpful.
