External Light Bulbs — Replacement (Audi 80 B4)

High and low beam headlights

All headlight bulbs are removed from the engine compartment. In order to remove the corresponding bulb, it is necessary to perform some actions to provide access to the bulb.

Depending on the engine type, to access the bulbs in the right headlight, you need to remove the rubber cuff from the headlight cover, press the retaining clips and remove the middle part of the cover. In some cases, you also need to remove the air intake sleeve. On cars with six-cylinder engines, you need to remove the battery cover to access the bulbs in the left headlight, and on cars with a five-cylinder engine, you need to remove the cover above the radiator to make room for working on the left headlight.

The headlight cover on cars with four- and five-cylinder engines is removed from the engine compartment by turning it to the left.

In cars with six-cylinder engines, the low and high beam headlight bulbs are covered with separate covers secured with wire clips (see illustration 10.0).



Access to the bulbs of some headlights is difficult. For this reason, the headlights themselves have to be removed.



1. Disconnect the headlight plug.

2. Press down on the clip holding the bulb base and remove the bulb (see illustration).



The new headlight bulb should be installed so that the three contact projections form an inverted "i".

Install the new headlight bulb in a car with a six-cylinder engine so that its base fits into the hole in the socket.
