HEADLIGHT DIPPING WARNING COMES ON. MULTIPLE COMPLAINTS TO AUDI AND ON OTHER FORUMS WITH OTHERS HAVING SAME PROBLEM. THIS IS A VEHICLE SAFETY ISSUE DUE TO HEADLIGHT GOING OUT DURING RANDOM TIMES WHILE DRIVING. AUDI IS FULLY AWARE THAT OVER 70 PERCENT OF ITS A4S HAS THIS PROBLEM WHICH IS A MAJOR CONCERN AND REFUSES TO FIX OR RECALL THE LIGHTS. THIS CAN HAPPEN ON A NEW VEHICLE PER MANY PEOPLES COMPLAINTS ONLINE. *TR
RIGHT MIRROR TURN SIGNAL LIGHT FAILED
I HAVE A 2009 AUDI A4, WITH 26K MILES. THE LEFT HEADLIGHT WORKS INTERMITTENTLY. THE DEALERSHIP STATED THAT I NEED TO REPLACE THE BULB, BUT ON FURTHER RESEARCH I HAVE FOUND THAT SEVERAL OTHER FOLKS HAVE HAD THE SAME ISSUE. THIS IS A MAJOR SAFETY ISSUE AND THERE APPEARS TO BE A DEFECT THAT THE MANUFACTURER IS NOT COVERING IN THE WARRANTY. CAN YOU PLEASE HELP RESOLVE? *TR
