We have classified the 2 complaints from 2001 Audi A4 about EXTERIOR LIGHTING into the following categories.
We have experienced an intermittent problem with the hid head lights flickering and shutting off during operation at night. the left low beam began to flicker and then shut off. the head light warning indicator light comes on. after inspection the next day, lights came back on and were working normally no warning lights were on. this appears to be a common problem with this type of car and in my opinion a very dangerous one that needs to be addressed by audi in a recall for the obvious ballast, bulb, wiring, problem that exists on this car. *tr
In 2007 xenon headlights dropped/dipped headlight level sensor replaced and lights appeared to work correctly. in 2011 the same problem occurred again. headlight leveling sensor and wiring harness replaced. appears to be working ok. driving with the headlights aimed incorrectly is a dangerous driving condition. it appears that there is a common design flaw with the xenon headlights. *tr
