I leased on brand new 2006 audi s4 on july 29,2006. In december 14,2006 this car developed a problem with the power steering of car. The car was taken to the dealership for repairs. This took four days. Two weeks later this car was towed to the dealership for power steering problem. This time they replaced the power steering rack which total a twenty-three day repair. On march 24,2007 the car was once again towed to dealership and I was told the clutch of vehicle was no good.

Intermittent headlight malfunction. Over the course of a year and a half of ownership, the right headlight has malfunctioned (turned off), with no consistent cause apparent. The specific error message that appears in the driver information screen is "right headlight dipped". This condition is both unsafe, and illegal - as many states will issue a traffic violation for driving with a non-functioning headlight.

My 2006 audi s4's low beam headlights flicker while driving on very cold days. Occasionally, my left or right headlight will turn off completely. I haven't had both go out at the same time, but I am worried that this will occur eventually. The flickering is very dangerous as it happens at low speed while I am driving through my neighborhood. I am worried that I will not be able to see children crossing the street going to school.

Hid xenon headlights randomly flicker and shut off during driving. It's getting worse. Dealers "never found" problem which recurs continually so they never fixed this issue under warranty after being asked several times since the vehicle was new. 100's of other stories about this online. Huge safety issue when headlights just quit at random.
