We have 2011 Octavia. Have tried replacing rear wiper motor. Removing the wiper arm was a bit tricky and we bought a removal tool which was a game changer. 

New motor duly installed. Only trouble is when water spray operates a load of water comes out around the hose attachment. It is slightly different fitting on this motor than old one. We must be doing something daft. Thank you!!

Also meant to say that it is the square base that the water gushes out of not the pipe. Makes the boot smell nice but a bit wet😄
