Bulbs
Replacing light bulbs
For your safety, we recommend that you have
your authorized Audi dealer replace burned out bulbs for you.
It i s becom ing 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 ab le 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 .
