For the VW Jetta TDI cup edition thunderbunny body kit front bumper removal or mk5 Rabbit, see 1000q: Cup edition bumper removal. The procedure is different because they don't have the chrome shield grille.
T30, T25 torx screwdriver/bit
Remove the front grille
Open the hood and remove the 2x T25 torx screws (yellow arrows) holding the grille to the
bumper. The green arrows are clips that you will remove later.
Remove the 2x phillips screws holding the grille. Note - they are at an
angle to the bumper.
This is what will come off.
Release the clips holding the grille (green arrows shown in the first
picture) and it will come off. There are also little hooks at the corners
shown below (yellow arrows) that will snag the bumper. Release them and
gently pull the bumper off starting at the top.
Remove the bumper
Remove the 2x T30 torx screws under the grille that hold the bumper (green arrows in the above picture).
Remove the 8x T25 torx screws along the bottom lip of the bumper. 4 of
them are shown below.
Remove 5x T25 torx screws along the front wheel well that hold the
bumper. One of them is at the corner and is vertical, all others are
Slide the bumper forward. As it comes forward, wiggle the side marker
lights out. The bumper should come off easily. If it doesn't there
are still torx screws holding it somewhere. The only other possibility is
if you have headlight washers but this should be obvious.
Installation is the reverse of removal. Make sure that you slide the
bumper onto the alignment brackets on the sides, highlighted below.
If the bumper can't get back on, feel free to post in the forums linked at the top to see if anyone else had this problem.
