  Q: How to access and remove the headlight and car bulbs on Audi 90?

  A:

  Access to the rear of the right-hand headlamp unit is gained by removing the air cleaner inlet hose, while for the left-hand unit on 90 models, the radiator upper cover must be removed. To remove a bulb on 80 models, turn the rear plastic cover anti-clockwise, remove it, and then pull the wiring plug from the bulb terminals. On 90 models, release the spring clip and remove the rear plastic cover before disconnecting the wiring plug from the bulb terminals. The bulb can be removed by releasing the spring clip. If the bulb is to be re-used, avoid touching the glass with bare fingers; if touched, clean it with methylated spirit. To remove the headlamp, first take off the washer components if fitted, and disconnect any relevant wiring for electric beam adjustment systems. On 80 models, disconnect the wiring plug(s) from the rear of the headlamp, potentially removing the direction indicator lamp first, then unscrew the upper and lower mounting screws to withdraw the headlight. For better access, the narrow trim strip may be removed from under the headlamp. On 90 models, disconnect the wiring plug from the rear, unscrew the upper and lower mounting screws, and withdraw the headlamp forwards. If necessary, the lens may be removed by prising off the spring clips with a screwdriver. Refitting is a reversal of removal; when fitting the headlamp, tighten the upper mounting screws first, then the lower screws, and adjust the headlamp as needed. When fitting the bulb, ensure the centre terminal is positioned at the top for proper engagement of the bulb rim location lugs, and if the plastic cover is marked 'Oben', it should be uppermost when fitted.

  Q: How should Car Bulbs be renewed and replaced on Audi 90?

  A:

  Bulbs should always be renewed with ones of identical type and rating. To replace the front sidelight, remove the plastic cover from the rear of the headlamp, disconnect the wiring plug if applicable, pull the bulbholder from the reflector, depress and twist the bulb to remove it, and refitting is a reversal of removal. For front direction indicators on 80 models, turn the bulbholder anti-clockwise to remove it, depress and twist the bulb to remove it, and refitting is a reversal of removal. On 90 and Coupe models, unscrew the cross-head screw to withdraw the front direction indicator lamp, turn the bulbholder anti-clockwise to remove it, depress and twist the bulb to remove it, and refitting is a reversal of removal. For front fog lamps on 80 models, use a screwdriver to prise off the plastic frame, unscrew the cross-head screws, withdraw the foglamp, disconnect the wire, unhook the spring clip, remove the bulb, and ensure proper engagement with the reflector during refitting. On 90 and Coupe models, remove the front direction indicator lamp, unscrew the two cross-head mounting screws, pull out the lamp, disconnect the wiring plug, unhook the wire clip, remove the lamp rear cover, disconnect the wire leading to the bulb, unhook the spring clip, and ensure correct engagement with the reflector during refitting. For the rear lamp cluster on the boot lid of the Saloon, open the bootlid, prise out the plastic cover, turn the bulbholder anti-clockwise to remove it, depress and twist the bulb to remove it, and if necessary, unscrew the retaining nuts.

For interior lights, use a small screwdriver to prise the light from the headlining, remove the festoon type bulb from the spring contacts, and ensure the spring contacts are tensioned sufficiently during refitting.

For the map reading light on Coupe models, hold the grab handle down, unscrew the cross-head screws, remove the handle and light complete, disconnect the wiring plug, remove the festoon type bulb from the spring contacts, and ensure the spring contacts are tensioned sufficiently during refitting. To replace the side marker lamp, push the lamp rearwards to release it from the location hole, pull the bulbholder from the rear of the lamp, pull out the wedge type bulb from the bulbholder, and refitting is a reversal of removal. For the glovebox illumination lamp, remove the glovebox, pull the switch/bulbholder from its housing, depress and twist the bulb to remove it, and refitting is a reversal of removal. For facia switch illumination, prise the cover from the switch with a screwdriver, remove the wedge type bulb using a piece of tubing, press the new bulb firmly into position, and refit the cover.
