I have heard a lot about removing and replacing blocked windscreen washer jets but no one describes how to remove  one before replacement . Can anyone please let me know how I remove the faulty jet 

Moved this to a more relevant section, where you should get more views and replies

Im assuming its a mkII fabia 1.2 TSi

I recently did this, first you remove the 2 plastic scuttle nuts visible on the plastic cover plate when the bonnet is up. Lift or slide this out but not all the way, You should be able to get your hand underdeath and slide the small plastic clip from the jet then it will release the pipe which should allow you to hold the jet and slide it forward and lift up the back and it should wiggle free. Do the passenger side first as it is easier to get the plastic pipe off and you'll see how it is a push fit onto the jet. Don't forget to slide the small securing clip back when you refit of it will blow off under water pressure.
