Instrument cluster that shows safety information doesn't work so don't know what's issue with car
As many others have noticed on the b7 models of audi's. The passenger headlight will flicker and go out at random times, it is not a bulb problem it has been replaced multiple times. It is concerning when driving at night and randomly my headlight will shut off. Sometimes when I shut the car off and back in it will return. There is an electrical problem with these headlights as I have read in other places. Very dangerous and concerning they want to charge 1000+ dollars for every customer to put in a new headlight. It is their duty to ensure safety of their customers.
Xenon headlamps wiring all corroded and bare with no insulation left. Check with audi and they said our vehicle and vin is not part of any recall. Yet rcorrd-05v096-4498 in your database shows a mofification letter from vw to include our vin. There is no record according to audi service shops that show any recall work done to our headlights. I have attached a picture that shows the deteriation of the electrical wiring and headlamps to our 2004 audi s4. Would appreciate some assistance to having our headlamps replaced for safety reasons.
Heated seat element burned or melted the seat while the car was off overnight. Passenger seat leather is now separated, shriveled (hard as a rock) and would have burned the passenger if they had been in the seat.
Tl* the contact owns a 2004 audi s4. While driving at night, the low beam head lamps failed to illuminate without warning. While attempting to the head lamp bulbs, the contact noticed that the wiring was burned and damaged. The dealer and the manufacturer were notified of the failure, but the vin was not included in any recalls. The approximate failure mileage was 79,000.
I just happened to look up recalls and saw the complaints on the audi s4 2001. I noticed my car wasn't the only one where the instrument cluster has lost pixels and ends up unreadable for all warnings and manufacturer programmed safety warnings. It has been like this for years and did ask my dealer how much it would cost to fix it and it was insane. It is a real safety issue. Audi should be responsible for fixing it. I didn't realize other audi's were having the same issue. Maybe if more people complain, audi will be forced to fix it.
As I was driving on the freeway my headlight went out with and the message, "right dipped headlight" came on. When this happen I stopped to fill up with gas and when I started the car the message was gone and the headlight was back on. This has happened a several more times since then. *Tr
The instrument cluster on all the audi s4s and also on vw loose pixels on the dash and it goes out, it is a hazard because this is a gauge that does a system check every time you start the vehicle, the car tells the driver if there are brake problems, engine problems, also if lights are out i.E. Brake lights turn signals, and also fluid status of the car. When this instrument cluster goes out or as audi calls it loses pixels, the driver does not know the status of the car which could cause safety and harm to the...

operator. It has been documented many times and has been replaced on my car over 4 times and is a common occurrence with other audi owners. Also the window regulator clip that holds the window breaks as well, audi and vw did a recall vin specific models of the beetle jetta and a4 but not the s4, the clip is the same design that is used in my vehicle. It also has been documented many times of failing and causes another safety issue, if the clip breaks the window will roll down unexpectedly, i.E. Causing the window to break which throws glass all over the occupants in the car and also exposes limbs to objects outside of the vehicle without knowledge. Many complaints have been made about this design flaw. I have tried to resolve these issues with audi multiple times and phone calls and multiple emails, regardless of the age and miles on my car, it is the same things that keep breaking, causing these safety issues. Both of these issues have been an ongoing problem from day one when these designs were put on the market. And replacing these items is necessary to ensure the safety of my occupants and myself. They need to be redesigned and revamped to solve these issues. Replacing them every single year is not acceptable. And even more so when someone's life is at risk, due to a bad and careless design. *Tr
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. *Tr
While driving, the right headlight flickered and went off (hid lights). The information system registered an error "dipped right headlight" head light comes on when ever the car is started, and goes out with the same error again at a later time. So far this error has occurred the last 3 times I have driven (all three times since first occurrence). This is a safety issue since night illumination is involved. I have read on internet audi websites that this is an all too common problem, that audi of america is not taking seriously as far as offering a clear solution. *Tr
Audi 2006 s4, there is a more frequent occurrence of my "headlights dipping" my xenon headlamps will stop working while driving, it would either be the left or the right, but not until last week when both went out at the same time. I would put car in neutral while driving and turn car off and back on and it will reset itself and lights will then work, it seems to stop occurring when car is warmed up and it is worse with colder weather and vibration or bad roads. It will occasionally occur when car is even warm well...

after 30 minutes, I am now concerned because last week both went out at the same time, that had never happened before, it was always one or the other, it has happened for the past 18 months or so. Audi has no answer, they have erroneously replaced working xenon lights, ballasts, etc and it continues to occur to many individuals that I read up on in audi forums. Frequency is now each and every time I start car and get going literally feet to less than a block. When it first started, it was once a couple of weeks, then once a week, to once every couple of days, to now each and every time at least a couple of times until warm. I am in colder climate, detroit, mi. *Ln
Car started misfiring and within less than 5 miles in the highway then started to build up smoke inside the cabin, car then stopped and towed to a mechanics who confirm the diagnosis of misfiring of 3 cylinders and found overheating of the passenger side catalytic converter that lead to a melting a connector of the transmission. *Tr
Abs sensor failure on 2000 audi s4 quattro. Light came on at 114,213. Leading to the brake light to flash along side of it and beep every other minute when your driving down the road. Haven't corrected the problem because I've heard it cost 1,700. Some people don't have that kind of money. Many other people are experiencing the same problem on vw's as well as the audi in years from 1996-2001. *Tr
Tl*the contact owns a 2000 audi s4. The contact stated that the instrumental cluster does not work in his vehicle. Occasionally, he is unable to read the display panel. The dealer quoted him a cost for the repair, but did not provide any other assistance. The failure mileage was 100,000.
I own a 2000 audi s4. My instrument cluster has an lcd display that displays information like outside temperature, possibility of icy conditions when the temperature is low enough to warrant these conditions, average mpg and other information of this nature. This screen also give safety warnings like bad headlight, taillight, license plate light, worn break pads, low washer fluid, low engine oil as well as others. This screen, as described in the owners manual, does indeed provide critical safety information about the automobile. *Tr
