Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

A4 4-cyl

My Audi A4 constantly will get a dipped headlight, meaning that the hid lights will dip and fail to stay on. It happens on both sides and will happen at night. I have driven in complete darkness and had both lights fail, if I turn the lights off for a few seconds and back on they will reset but it does not take long before they do it again and it is something that concerns me anytime I drive during dark times. I live in a area with snow and ice in the winter and also have to deal with deer and pedestrians during the summer. My lights going out all of a sudden for no reason has me questioning the safety my car provides. I am concerned that I may have my lights go out and wreck, or potentially hit a animal or person.

Headlights constantly flicker and then go out. Turning them off then on will only bring them on for a few seconds. I have had bulb replaced no results, though very expensive. My last Audi burned to the ground due to similar defect. Couldn't imagine this would happen again. Have reached out to Audi with no response.

1) headlights are the main problem. The car has the type of lights that move when turning the wheel. Occasionally, the headlights will "flicker" whether or not you are turning the steering wheel but will remain on. This is a nuisance but may be related to the next, larger problem. The larger problem is, almost every night there will be a "headlight dip" warning signal on the instrument panel. When this happens rarely will the headlights stay on anymore. They used to do so, but now one or both of the headlights will frequently turn off. We used to be able to "override" this by moving the headlight switch on the dash from the auto to the manual mode and off mode. However, now we have to switch back and forth multiple times before the headlights turn back on and it takes a lot longer now than it used to. (the headlights are staying off for longer periods. ) also, even when you leave the headlight switch in the manual mode (rather than use the auto mode at all), the headlights will still dip and turn off.

The contact owns a 2005 Audi A4. The contact stated the headlights shut on and off while driving. When the failure occurred the instrument panel would display headlights dipped on the instrument. The contact took the vehicle to the dealer who was told the engine vibration caused the headlights to shut off. The dealer placed rubber pieces into the casing in order to minimize the vibration. The failure mileage was 43,000 and the current mileage was 62,000.

  • 75,000 miles
While driving the headlights (either left or right or sometimes both) will just go out. Happens on the freeway, happens in the driveway or on a surface happens nearly every time I drive with the headlights on. Audi can't replicate the issue when I bring it in and doesn't have a fix. Many people report that replacing headlight bulb or ballace didn't fix problem. This is very dangerous as they just flicker and go out. There really should be a recall as this is a very common issue on the A4.

2005 Audi A4 2.0T - headlights malfunction. Warning sign comes on "left/right headlight dipped out". during night, this is extremely dangerous. Only way to get lights back on is to either turn headlights off and back on again or pull over, turn car off and restart. This is only a temporary fix though. Within 10 to 15 min, the headlight will "dip" out again (light flickers and goes out). Changing bulbs do not help. Changing ballast does not help. Within a 20 mile stretch, my headlights will "dip out" and black out on average of 3 times. This makes for very unsafe driving conditions.

Defective headlight assembly. Google "dipped headlight Audi". causes rampant flickering that blinds everyone on the road or turn off your headlight and drive in the dark at night. Changed bulb does not fix it. Changed ballast does not fix it.

Problem occurs when the lights are turned on at night, the right headlight begins to flicker and then shuts off with an error, "right dipped headlight". it occurs every night, which is dangerous and hazardous and makes it difficult to see and obscures the view to drivers of oncoming traffic. This problem is being suffered by a large numbers of owners and it should be recalled by the manufacturer.

A4 4-cyl

  • 92,000 miles
My 2005.5 Audi A4 quattro frequently experiences hid headlight problems, typically starting with a rapidly flickering headlight and then followed by the headlight(s) extinguishing. When this happens, there is a right or left dipped bulb failure indicated on the dashboard. The headlights can be restored by cycling power. This problem is occurring more frequently; currently it occurs at least every 30 minutes and seems to be triggered when braking the car to a stop, gently accelerating in lower gears, or when turning while climbing or descending steep hills. When this condition is experienced, the headlights flicker rapidly and eventually extinguish. Restoring the affected headlight requires me to either pull off the road and cycle power or to manually turn the lights off and on while driving. This is unsafe, probably illegal, and very annoying to the driver and others in traffic. I had this condition repaired previously under warranty (40K miles), but it has recently returned and worsened. My Audi now has 92K miles and is out of warranty. I am surprised that Audi has not offered a cost-free recall action to fix this safety problem, particularly given its prevalence in Audi A4's. the cost to repair this obvious design defect is high and apparently could involve replacement of the hid bulbs, igniters, and sensors.

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 happened about 7-8 times, the headlight flickers, then goes out, but will come back on when the car is restarted, then be fine for weeks or months at a time. The dealership has been notified of the problem on at least 3 visits, and has claimed that everything is fine and they can not reproduce said error. They have suggested/guessed that it is the xenon light bulb itself, however it has checked out fine each time, and as mentioned, has functioned flawlessly after each occurrence with merely a restart of the vehicle. No parts have been repaired or replaced, however they have claimed to perform a visual inspection of the electrical connections on at least one visit. Given the availability of information online and by word of mouth from other fellow Audi owners, this problem is not limited to just my case. I would like Audi to step up and address this issue not only for their own pr, but for their customers' safety.

A4 6-cyl

  • 42,300 miles
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 repair suggestion (just live with the problem I guess). Also, it appears that this happens on the 2002-2005 models as well as the 2005.5 - 2009 models of the A4. This is a known issue that Audi doesn't seem to want to address. Dealer has estimated the "O" ring replacement to be about $250 (for a $1 part!).

  • 45,000 miles
The passenger side xenon headlight unit flickers off and on and eventually go out while driving at night. Turning headlights off and on while temporarily relieve the problem (sometimes less a few seconds, others time 30 min or hour). When problem started a couple years ago, time between the problem was long (weeks). The problem has persisted and now happens every time I drive at night. When problem first occurred (car under warranty, ~45K miles), nothing was found to be an issue by the dealership as the problem could not be replicated at the point of inspection. Unfortunately, the car is now out of warranty. From things I've read, Audi failed to program fault tests for the headlights, making the problem hard to diagnose. Additionally, many Audi owners spent large amounts of money trying to replace bulbs and replace ballasts (very expensive) only to have the problem persist. I've encountered a couple owners that have actually had charred connectors of the electrical connections affiliated with the lighting system (fire hazard?). the defective nature of the system is an obvious safety issue. Please help facilitate an acceptable response program from Audi.

Audi A4 (2005) - Audi is apparently aware of the problem with the "dipped headlights" in their vehicles, but will not offer a fix to owners. If one does an internet search you can find literally dozens of sites dedicated to this issue and people trying to get a resolution. This problem causes one or both of the hid headlights to flicker and go out while driving and repeats even when the lights are turned off and back on again. Aside from it being a safety issue, it's also causing owners in the form of driving violations, etc...and yet Audi usa refuses to address this well known issue.

Bought 2005 Audi 3.2 quattro A4 with 57500 miles have driven aprox 3000 miles and headlights have started to flicker and the left highbeam is starting to fail. I get error message that headlight has dipped. It then shows headlight failed symbol. I turn lights off and on and headlight comes back on. I see from online research that this a common problem with Audi owners with no fix from Audi.
