Can the compressor be removed by only removing the front bumper and not having to jack up the car?

 

To remove bumper you will have to remove bolts holding bottom of the bumper facia and first section of the splash tray. There are also screws holding bumper facia to wheel well splash shield.
Can it be done? Yes. but why would anybody do it that way?! It is way more difficult than just removing wheel well shield!

 

Ya definitely leave the bumper on. I think I removed just the front section of the under-tray and the wheel well liner.

 

Tyre and Wheel well liner removed is all you need.
3 x 10mm nut, two plugs, inlet airfilter hose and naturally the 4mm brass fitting for the nylon hose.
if you have never done it before take a picture of the rubber , springs, esp . The bracket
