How do you change a parking lamp bulb on an Audi TT?

To change the parking lamp bulb on an Audi TT, first, ensure the vehicle is turned off and the keys are removed. Open the hood and locate the headlight assembly; you may need to remove any covers or clips. Twist the bulb socket counterclockwise to release it, then remove the old bulb and replace it with a new one, taking care not to touch the glass. Reinsert the socket, secure any covers, and test the new bulb before closing the hood.
