OVER THE COURSE OF NEARLY TWO YEARS OF OWNERSHIP, THE RIGHT AND LEFT HEADLIGHTS HAVE MALFUNCTIONED (TURNED OFF), WITH NO CONSISTENT CAUSE APPARENT. THE SPECIFIC ERROR MESSAGE THAT APPEARS IN THE DRIVER INFORMATION SCREEN IS "RIGHT/LEFT HEADLIGHT DIPPED". THIS CONDITION IS BOTH UNSAFE, AND ILLEGAL - AS MANY STATES WILL ISSUE A TRAFFIC VIOLATION FOR DRIVING WITH A NON-FUNCTIONING HEADLIGHT. IT HAS H…

MY CERTIFIED PRE OWNED 2005 A4 HAD THE XENON HEADLIGHTS CHANGED 3 TIMES IN 1.5 YEARS WHILE UNDER WARRANTY. SIX MONTHS AFTER THE 50,000 WARRANTY, THE LIGHTS STARTED FLICKERING AND THEN DIMMED AND FLICKERED WHILE DRIVING AT NIGHT WITH NO WARNING ON THE DISPLAY. I WENT TO THE DEALER AND BOTH HAD TO BE REPLACED AT A COST OF $430 FOR THE TWO LIGHTS AND $236 DOLLARS INSTALLATION COST. I HAVE OWNED THE …
HEADLIGHTS ON MY 2005 AUDI A4 SEDAN VIBRATE AND FAIL, SENDING AN ERROR MESSAGE READING "DIPPED HEADLIGHT FAILURE". THIS HAPPENS MORE WHEN IT'S COLD OR WET. VARIOUS ITEMS HAVE BEEN REPLACED. ISSUE IS INTERMITTENT. NOW OUT OF WARRANTY. THIS DANGEROUS CONDITION IS VERY EXPENSIVE TO REPAIR, IF THE DEALER IS CAPABLE OF REPAIRING. I'M LEARNING THAN MANY OTHER AUDI OWNERS HAVE THIS SAME PROBLEM. *TR
2005 AUDI A4 2.0 TURBO. THE HEAD LIGHTS GO OUT AND THE SENSOR SAYS "DIPPED LIGHT", NEED TO SHUT LIGHTS OFF AND THEN PUT THEM BACK ON. I HAVE BROUGHT IT TO THE DEALER 3 TIMES AND THEY SAY THEY KNOW THAT THEY HAVE A PROBLEM ON ALL THESE CARS BUT, "DO NOT KNOW HOW TO FIX IT". THEY CLEANED THE TERMINALS BUT IT DID NOT WORK. THERE ARE THOUSANDS OF SIMILAR COMPLAINTS ON THE LIGHTS. *TR
THE LEFT HEADLAMP WILL FLICKER AND THEN DIP TOWARDS THE GROUND WHILE DRIVING, A DASHBOARD WARNING SAYS "LEFT HEADLAMP DIPPED". THE CAR HAS BEEN TO THE AUDI DEALER SEVERAL TIMES AND THEY ARE UNABLE TO REPLICATE THE ISSUE, AND TELL ME THE FAULT DOES NOT GENERATE A COMPUTER CODE FOR THEM TO CHECK. IT HAS STARTED HAPPENING ON A MORE FREQUENT BASIS, AT DIFFERENT SPEEDS AND ON DIFFERENT ROAD CONDITIONS.…
WHEN DRIVING DOWN THE CITY STREET OR HIGHWAY, I WOULD GET THE "DIPPED LIGHT" WARNING ON MY DISPLAY, THE HEADLIGHTS WOULD FLICKER AND THEN SHUT OFF. I HAVE HAD THIS CHECKED AT THE SERVICE DEPT AND NO FAULTS WERE FOUND ON MORE THAN ONE OCCASION INITIALLY. THEN, THE HEADLIGHT BULB WAS REPLACED AT ONE POINT AS ADVISED BY THE SERVICE DEPT OF THE DEALERSHIP. HOWEVER, IT DID NOT SOLVE THE PROBLEM. I NO…
EXCESSIVE MOISTURE IN BOTH HEADLIGHTS. DEALER STATS THAT AN "O" RING HAS FAILED AND INFERS THAT THIS IS A DESIGN PROBLEM. STATES THAT MOST HEADLIGHT ASSEMBLIES WILL CLEAR UP WITHIN ABOUT 10 MINUTES. MINE HAVE SO MUCH MOISTURE IN THEM THAT I HAVE WATER DRIPS. THIS CAUSES THE LIGHT OUTPUT TO BE VERY DIM. AUDI HAS A TSB THAT STATES THE LIGHT ASSEMBLY SHOULD NOT BE REPLACED, AND HAS NO OTHER REPA…
I DRIVE A 2005.5 AUDI A4 2.0T. WHEN I TURN MY HEADLIGHTS ON NEARLY HALF THE TIME THE RIGHT HEADLIGHT SHAKES, THEN FLICKERS, THEN TURNS OFF ONLY TO TURN BACK ON A FEW SECONDS LATER AND THE PROCESS CONTINUES THE ENTIRE DRIVE. UNLESS I TURN THE HEADLIGHTS FROM AUTO TO OFF AND THEN BACK TO AUTO AND IT SEEMS TO FIX THE PROBLEM DURING THIS TRIP. I'VE TAKEN THE CAR TO THE AUDI DEALER WHICH I PURCHASED …
LEFT HEADLIGHT (BI-XENON TYPE) FLICKERS THEN FAILS ON OUR 2005 AUDI A4 QUATTRO. THE ONLY WAY TO BRING THE LIGHT BACK ON IS TO TURN OFF THE HEADLIGHT SWITCH AND TURN IT BACK ON AGAIN - AT NIGHT, THIS MEANS SEVERAL SECONDS WITH NO HEADLIGHTS ON - WHICH MEANS THAT YOU MUST PULL OVER TO A SAFE PLACE ALONG THE ROAD (WHICH SOMETIMES IS NOT POSSIBLE) TO CYCLE THE SWITCH. THE LIGHT WILL OFTEN SHUT OFF S…
HEADLIGHTS WILL TURN OFF FOR NO REASON. FOGLIGHTS WILL ALSO CYCLE ON AND OFF. NO SOLUTION. EXTREMELY DANGEROUS SITUATION. *TR
Common questions
How serious is the lighting problem on the 2005 Audi A4?
It's a documented issue but not catastrophic. 85 complaints have been filed. Repairs average $250 and most owners catch it before it causes a breakdown.
At what mileage does the lighting typically fail?
Mileage data is limited for this issue. Owners report failures across a wide range, suggesting cause is more about driving conditions and maintenance than mileage alone.
What does it cost to fix?
Independent shops typically charge around $250 for lighting repairs on this vehicle. Dealer pricing tends to run 20-40% higher. The exact figure depends on the specific failure mode, parts availability, and your local labor rates. If you're outside factory warranty, an extended service contract often covers this category.
Are there any recalls related to lighting?
No active recalls currently cover lighting issues on this vehicle. The complaints filed represent owner-reported failures that haven't risen to the level of a manufacturer-issued recall — but they're still worth knowing about before you buy or budget for repairs.
