Lighting on the 2006 Audi S4 Avant is managed by a total of 9 bulbs, covering everything from primary headlights to signal indicators.

This vehicle is known to use a CANbus system. Installing standard LEDs may cause flickering.
Can You Put LED Bulbs in a 2006 Audi S4 Avant?
Upgrading to LED is one of the most effective ways to modernize your Audi's appearance and safety profile. Since your S4 Avant uses a single H7 bulb for both high and low beams, ensure your chosen LED kit is "dual-beam" compatible. This allows the LED circuitry to mimic the two-filament design of the original halogen bulb. Because Audi utilizes a CANbus system, standard LED bulbs may cause "bulb out" errors on your dashboard. Always opt for "Error-Free" or CANbus-ready kits which include the necessary resistors. Don't forget the H11 fog lights; switching these to LED can dramatically improve your visibility in adverse weather.
