Notes:

To replace headlight bulbs in vehicles equipped with halogen headlights, the bulbs can be replaced without removing the headlight. How to do this is described below. To replace lamps with gas discharge (xenov) lamps, due to the design features, it is necessary to completely remove the headlight from the vehicle. In addition, replacing xenon lamps sometimes does not completely solve the problem of weak headlight, then it is necessary to check the remaining parts and clean the lenses.

Over time, the luminous intensity of the headlight lamps noticeably decreases. The main reasons are the deterioration of the characteristics of the lamp itself, as well as contamination of the lens. Headlights may start to flicker, change color to pinkish, and simply fail. These are sure signs for replacing the lamp, as well as checking the rest of the components of the headlight.

Before carrying out work, turn off all electrical consumers in the car and turn off the ignition. Open the battery cover and disconnect the negative terminal.

Replacing halogen headlight bulbs without removing the Volkswagen Passat headlight

1.  To replace all three types of lamps, it is necessary to remove the cover of the required lamp.

A - parking light lamp

B - low beam lamp

C - high beam lamp

Note:

An example is shown on the left headlight. The location for the right headlight is symmetrical. All three types of lamps change approximately the same.

2.  Pry off the cover of the desired lamp, put your hand behind the headlight, pull the cover from side to side and pull it out.

3.  Put your hand into the niche of the lamp.

On the Hella headlight, feel for and turn the bulb holder and turn it counterclockwise. Remove the bulb socket. Be careful not to damage the wires.

On the Valeo headlight, pull the wire terminal in the opposite direction of the vehicle. After removing the terminal, remove the lamp by the plug from the reflector.

Note:

The type of lamp sockets for Valeo and Hella headlights is different. At the Valeo headlight, the low beam lamp is placed in a niche and then a terminal is connected to it. At the Hella headlight, the low beam lamp is inserted into a plastic base, which is already connected to the wires.

4. Remove the bulb from the socket.

5. Replace the bulb with a new one and insert it into the socket.

6. Insert the cartridge back and turn it clockwise until it stops. In the Valeo headlight, the lamp must be inserted all the way and the wire terminal connected. Close the niche tightly with a lid so that dirt and moisture do not get there.

7. Check the operation of the headlight, including all its functions.

8. Check the headlight setting, adjust if necessary.

Warning:

It is highly recommended that you wear clean cotton gloves when handling the lamps. In addition to the fact that the lamps are quite fragile and can burst right in the hand, this is also important for a new lamp. It is undesirable to touch it with bare hands, since dirt and grease on the lamp glass significantly reduce the life of the lamp.

Replacing lamps in a car equipped with xenon headlights (with the removal of the headlight) Volkswagen Passat

1.  To replace the bulbs and gain access to the lens, the front bumper trim and grille must be removed as described in  this article .

2.  Unscrew the two screws of the headlamp top mounting.

3.  Turn off three directing bolts under a headlight and remove a lath.

4.  Unscrew the two side screws securing the headlight.

5.  Disconnect the terminal of the headlight power wires.

6.  Remove the headlight by pulling it towards you.

7.  Remove the bracket at the rear of the headlight housing.

8.  Pull the cover together with the lamp ignition unit to the other side of the bracket. Do this carefully, as there are wires attached to the cover that will need to be disconnected.

Note:

Do not remove the ignition unit from the cover unless it needs to be replaced.

9.  Disconnect all wire terminals from the headlight cover.

10.  Next, there are two options depending on the performance.

Disconnect the terminal of the wires suitable for the lamp (highlighted by a frame) and fold the latch (movement is shown by an angular arrow).

Or put your hand into the headlight housing, turn the square base of the lamp counterclockwise, pull the lamp out and disconnect it from the wire.

11.  Remove the dipped beam lamp and replace it with a new one if necessary. Remember not to touch the lamp with bare hands.

12.  To replace the parking light bulb and cornering light bulb, you need to open the oval cover at the back of the headlight housing. To do this, open the two latches on the top and bottom of the cover.

13. Remove the turning light bulb (1) or parking light bulb (2) from their sockets, disconnect them from the sockets and replace with new ones.

As a cornering lamp, a conventional halogen lamp is used, which is used in headlights with halogen light (VAG N10320102).

14.  Install the lamps and all other parts in reverse order.

15.  Check the operation of the headlight, including all its functions.

16.  Check the headlight setting, adjust if necessary.

Cleaning headlight lenses or repair/replace headlight unit Volkswagen Passat

1. To enhance the effect of replacing the lamps, you can try to clean the lens and headlight cover. To do this, you need to make a long manual mop from a wire tightly wrapped in a towel.

2.  Run a mop through the lamp hole, bending at different angles, wipe the lens and headlight cover.

3. It should be noted that it is impossible to wipe everything with a mop without disassembling the headlight housing (it is non-separable in design). In some cases, users turn to an additional cleaning method. All lamps and headlight electrical units are removed, the wires are insulated and warm distilled water is poured into the headlight housing with the addition of a cleaning degreaser. Then the water is drained and the headlight is dried in the most thorough way. This can be done either in the oven or naturally.

Warning:

This kind of cleaning is inevitably associated with the risk of water ingress and incomplete drying of electrical contacts. Pay special attention to drying the headlight. You perform all operations at your own peril and risk!

4. Repair or replace headlight assembly.

Note:

If replacing the bulbs and wiping/washing the headlight does not solve the problem of weak head light, then either a complete replacement of the headlight assembly or its disassembly and subsequent replacement of the lens reflectors is necessary. This disassembly is not provided by the manufacturer. Faro will either have to cut or peel off the cover. This is a very time-consuming procedure that will take a lot of time and requires good technical training. It is performed incl. specialized workshops.
