For your safety, we recommend that you have
your authorized Audi dealer replace any bulbs for
you.
It is becoming increasing ly more and more diff i­
cult to replace vehicle light bulbs s ince in many
cases, othe r parts of the car must fi rst be re­
moved before you are able to get to the bu lb .
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 ho lders can have sharp
edges that can cause serious cuts, parts must be
correct ly taken apart and then properly put back
together to he lp prevent breakage of parts and
380
long term damage from water that can enter
housings that have not been properly resealed.
Fo r you r safety, we recommend that you have
you r autho rized Audi dea ler replace any bulbs for
you, since your dealer has the proper tools, the
correct bu lbs and the expertise.
Ga s di sc harg e la mp s (Xe non ligh ts):
