Bulbs
Replacing light bulbs
For your safety, we recommend that you have
your authorized Audi dealer replace any bulbs for
you.
It is becoming increasingly more and more diffi­
cult to replace vehicle light bulbs since in many
cases, other parts of the car must first be re­ moved before you are able to get to the bulb.
This applies especially to the light bulbs in the
front of your car which you can only reach
through the engine compartment.
Sheet metal and bulb holders can have sharp
edges that can cause serious cuts, parts must be
correctly taken apart and then properly put back
together to help prevent breakage of parts and
l ong term damage from water that can enter
housings that have not been properly resealed.
For your safety, we recommend that you have
your author ized Audi dealer replace any bulbs for
you, s ince your dealer has the proper tools, the
correct bulbs and the expert ise.
Fuses and bulbs
Gas discharge lamps (Xenon lights) :
Due to the high e lectr ical voltage, have the bulbs
replaced by a qualified technician. Headlights
with Xenon light are identified by the high volt­
age sticker .
LED headlights*
LED headlights require no maintenance. Please
contact your authorized Audi dealer if a bulb
needs to be replaced .
.&, WARNING
Changing Xenon lamps without the necessary
equipment can cause serious personal injury.
- Bulbs are pressurized and can explode when
be ing changed. Potential risk of injury!
- On veh icles equipped with gas discharge
bu lbs (Xenon light) life-threatening injuries
can resu lt from improper handling of the
h ig h-vo ltage portions of such lamps!
- Only your authorized Audi dealer or quali­
fied workshop should change the bulbs in
gas discharge lamps. There are parts with
sharp edges on the openings and on the
bulb holders that can cause serious cuts. If
you are uncertain about what to do, have the work performed by an authorized Audi
dealer or qualified workshop. Ser ious per­
sonal injury may result from improperly per­
formed work.
(D Tips
- If you st ill prefer to replace the light bulbs
yourself, be aware that the engine compart­ ment is a hazardous area to work
in¢ A in
Working in the engine compartment on
page 323.
- It is best to ask your authorized Audi dealer
whenever you want to change a bulb .
