  Q: How often should the headlight alignment be checked and How to adjust on Audi 4000?

  A:

  The headlight alignment should be checked every 15,000 km (10,000 miles) or 12 months, whichever occurs first, and it is recommended that this alignment is carried out by an Audi dealer using modern beam setting equipment. In an emergency, position the car on a level surface with correctly inflated tyres, approximately 10 metres (33 feet) in front of and at right angles to a wall or garage door. Draw a horizontal line on the wall or door at headlight centre height and a vertical line corresponding to the centre-line of the car, then measure off points on the horizontal line corresponding with the headlight centres. Switch on the main beam and check that the areas of maximum illumination coincide with the headlight centre marks; if not, turn the adjustment screws as necessary, with the upper screw controlling horizontal adjustment and the lower screw for height adjustment.

  Q: How to remove headlight and car bulbs on Audi 4000?

  A:

  To remove a bulb on UK models, open the bonnet and take off the plug and rubber cap from the rear of the headlight. Next, press and twist the retaining ring or unhook the clip to remove the headlamp bulb, ensuring not to touch the glass if it is to be reused. For Saloon models, take off the surround and front grille, disconnect the direction indicator wiring, loosen the front bumper mounting bolts, and press the bumper down as far as possible. Remove the side lamp bulb (if fitted) and the cross-head retaining screws, then withdraw the headlamp. On Coupe models, only the surround and the relevant retaining ring need to be removed. Refitting is done in reverse order. For North American models, sealed beam units are used; start by removing the screws from the surround, swinging it forward and lifting it out. Then, take off the relevant retaining ring, withdraw the headlamp, and disconnect the wiring. If needed, remove the screws and take out the mounting frame. Refitting is also done in reverse order, and if the mounting frame was removed, check the headlamp alignment.
