The Volkswagen Touareg is a popular SUV that combines traditionally handsome German lines with precision European engineering. In order to replace a headlight bulb, the Touareg's headlight housing must be removed. The housing will also need to be removed if you are replacing a broken headlight lens. This is a relatively straightforward process that requires the use of a special tool that the vehicle comes with and which is kept with the spare tire.
Open the bonnet. Remove the side engine cover panels if your Touareg has them installed on the engine.
Insert the headlight crank tool into the hex bolt on the back of the headlight housing located below the sticker that says "Open, Close." The headlight crank tool is kept in the compartment for the spare tire.
Push gently on the front of the headlight assembly to release the tension on the housing while simultaneously turning the hex bolt with the crank tool. Turn the tool until the headlight assembly pushes partially out of its socket. Do not force the tool too hard or turn it too far to avoid breaking the chrome bar.
Locate the hole in the radiator bulk head above the headlight assembly that allows access to the headlight release clip. Insert a long, straight screwdriver and push down on the release clip to free the headlight.
Pull the headlight out while pressing on the clip. Once the headlight is moved out beyond the clip, use both hands to gently and carefully pull the headlight out. There are no wiring harnesses or cables that need to be disconnected.
Reinstall the headlight by sliding it into the cavity until you hear a click. Make sure the headlight slides in smoothly and that the two rails on the bottom line up with the tracks in the cavity.
Apply light pressure on the front of the headlight while you use the headlight tool to tighten the bolt that holds it in place. The crank tool will pull the headlight tightly into place. Continue to crank the tool until you here an audible snap, which indicates that the headlight is locked into place.
