Five problems related to exterior lighting have been reported for the 2003 Audi A4. The most recently reported issues are listed below. Please also check out the statistics and reliability analysis of the 2003 Audi A4 based on all problems reported for the 2003 A4.
Water pump failed inside lights sometimes work and signal lights aren’t accurate.
There is a failure with my high intensity discharge(hid) lights that causes them to flicker and sometimes to turn off completely while in use/ the failure occurs every time the hid lights are turned on. Bulbs have been changed, but the condition is not resolved. An alarm comes on screen which reads "left light dipped" or "right light dipped" and results in the light turning off completely on the dipped side.
At least quarterly I have to replace one or more bulbs. Within this past week my rr brake bulb & lr parking light blew.
Since I purchased this vehicle, the hid lights have sporadically flickered. Within the past year, they randomly flicker and sometimes turn off briefly making for a hazardous driving situation. I really wish Audi would fix this problem because there are hundreds of owners having the exact same problems.
Fuel pump failed, ignition coils have all been replaced twice.
