Changing bulbs
Introduction
This chapter contains information on the followingsubjects:
⇒ Checklist 
⇒ Changing bulbs in the headlights (halogen bulbsyf
⇒ Changing bulbs in the front bumper
⇒ Changing bulbs in the front bumper (R-Lineyf
⇒ Changing the bulbs in the tail light cluster in the body
⇒ Troubleshooting
Changing the vehicle bulbs requires considerable technical skill. Volkswagen therefore
recommends having bulbs replaced by a qualified workshop if you are uncertain. The work must
always be performed by an expert if other vehicle parts around the affected bulbs need to be
removed. Volkswagen recommends having bulbs replaced by a Volkswagen dealership.
You should keep a box with spare light bulbs for the lights that ensure the vehicle is roadworthy in
the vehicle at all times. Spare bulbs are available from Volkswagen dealerships. In some countries
it is a legal requirement to have these spare bulbs in the vehicle.
It may be illegal to drive with a defective bulb in the exterior lighting.
Worn or dirty windscreen wiper blades reduce visibility and increase the risk of accidents
and severe injuries.
•Always change wiper blades if they are damaged or worn and no longer clean the
window properly.
WARNING
Damaged or dirty windscreen wipers can scratch the windscreen.
•Do not use any cleaning agents containing solvents, hard sponges and other sharp
objects, as they can damage the graphite coating of the wiper blades during cleaning.
•Do not use fuel, nail varnish remover, paint thinner or similar products to clean the
windows.
NOTICE

Park the vehicle on a firm and level surface at a safe distance from the flow of traffic.
Switch on the electronic parking brake Electronic parking brake.
Turn the light switch to position 0 Lights.
Move the turn signal lever to neutral position Lights.
Move the automatic gearbox selector lever to position P DSG® dual clutch gearbox.
Switch off the ignition and remove the vehicle key from the ignition lock Starting and

Switch off the orientation lighting Lights.
Leave the defective bulbs to cool down.
You can change the following bulbs yourself:
•Bulbs in the halogen headlight: dipped beam, main beam, daytime running light, side light, turn
signal.
•Bulbs in front bumper: fog lights, static cornering light.
•Bulbs in the tail light clusters: rear turn signal, if it does not feature LED technology (depending
on vehicle equipment levelyf.
All other bulbs and lamps in the vehicle should always be changed by an expert.
Additional bulb specifications
Some bulbs in headlights or in tail light clusters might have factory specifications that are different
to standard bulbs. The designation is inscribed on the bulb, either on the glass part or on the base.
LED bulbs on the vehicle
•Brake light, rear fog light, tail light, turn signal and reversing light in the tail light clusters.
•Dipped beam, main beam, daytime running lights, static cornering light, side lights and turn
signal.
•Number plate light.
Owners cannot replace the LEDs themselves. If some LEDs fail, this may be an indication that
more elements are on the point of failure. If this happens, have the bulbs checked and replaced if
necessary at a qualified workshop.
Checklist Information on changing bulbs
First read and observe the introductoryinformation and safety warnings⇒
Introduction
Checklist
Always carry out the following actions for changing a bulb in the given order ⇒:
Accidents can occur if roads are not sufficiently illuminated and other road users have
difficulty seeing the vehicle, or cannot see it at all.
WARNING
Changing the bulb incorrectly can cause accidents and serious injuries.
•When working in the engine compartment, always read and observe the safety
warnings ⇒ In the engine compartment. The engine compartment of any motor vehicle
is a dangerous area. Serious injuries can be sustained here.
•H7/H15 bulbs are pressurised and could explode when they are being changed.
•Only change the defective bulb once it has had time to cool down completely.
•Never change a bulb unless you are familiar with the procedure. If you are uncertain of
what to do, the work should be carried out by a qualified workshop.
•Do not touch the glass part of the bulb with unprotected fingers. When the light is
switched on, heat will cause fingerprints to evaporate on the bulb, which in turn will
cause the reflector to dim.
•There are sharp-edged parts in the headlight housing in the engine compartment and
on the tail light cluster housing. Protect your hands when changing bulbs.
WARNING
Damage to the electrical system can be caused by water entering the system if the rubber
covers or plastic caps on the headlight housing are not properly mounted after a bulb has
been changed.
NOTICE

Check to see if a fuse has blown Changing fuses.
Follow the instructions to change the affected bulb . Always use identical bulbs with the
same designation. The designation is inscribed on the bulb, either on the glass part or on
the base.
Do not touch the glass part of the bulb with unprotected fingers. The heat of the bulb would
cause the fingerprint to evaporate and condense on the reflector. This will impair the
brightness of the headlight.
After changing the bulb, check to ensure that the bulb is working properly. If the bulb is not
working properly, the bulb may not have been inserted properly or may have failed again,
or the connector may have been inserted incorrectly.
Any time you change a bulb in the front of the vehicle, the headlight settings should be
checked by a qualified workshop.
