Takata recall audi has persistently denied anything wrong with the air bags and there is no sufficient process to remedy this. I called the dealership and there is no maintenance or service bulletin available. Audi headlights the left headlight is malfunctioning due to something with the adaptive head lights. Upon steering the car, especially on highway entries and exits, sharp turns, and windy road driving the error "dipped left headlight" will appear. Audi has consistently denied the problem as you need to be on the road for this problem to occur. Even driving to the service mechanic is deadly with only one functioning headlight and has been the only way for a mechanic to determine an issue is occurring. After that, the car must be left on and unlocked while registering the car.

My right headlight has been flickering for about 3 months, and a few times it has gone out completely. Turning the headlights off and back on fixes it for a couple days. I waited to take it to the dealer until it needed maintenance, and also so there would be more dtc evidence for them to troubleshoot with. The left headlight started doing the same thing so I took it in. Audi cannot replicate and will not replace the headlights.

Driving down the road and my car starts smoking and catchs on fire

Bi-xenon driver side headlight goes off randomly while driving at any speeds. Have to power off and on the headlights while driving to get the light to work again. This has been happening for years since I bought the car new. Audi service was never able to admit to the problem or fix it on multiple visits for service on the car. Huge safety issue...

I was driving down the highway and have continuously gotten the "dipped light" warning on my display. My lights procceded to flicker and then shut off. I was driving right next to a car and had to pull over because they wouldn't come on. It took 15 minutes before the headlights returned to normal. I was extremely scared when my headlights turned off. This is a big safety issue and has occurred 3 times since then. I have replaced the bulbs and that did not solve the problem. I know there is a tsb for this problem, but I think there is a need for a recall as I almost got into an accident on the highway.

I purchased this 2005 audi a4 in august of 2007 and within the first few months of having the vehicle I was already having problems with it having to take it in and get repaired/serviced. Not only was I dissatisfied that I bought a horrible car, because it was having recurring problems, but I find out after purchasing the vehicle the dealership sold me a quattro, but my audi is not a quattro, so I was mislead into buying a faulty vehicle.. My paperwork documentation says 2005 audi a4 quattro 1.8t so I had to pay to get towed out of the snow because the audi is only 2 wheel drive.. I will never ever purchase a vw/audi vehicle again and I always tell people don't get a vw/audi because they are horrible unreliable cars. I have put so much money into this junk audi that just constantly has problems, I could have bought a new car again by now . I'm very disappointed with vw/audi. I have wasted so much money on diagnostic repair checks, because the [xxx] check engine light repeatedly keeps coming on the dashboard. I can't get my car smog approved without the check engine light being off, so I am relentlessly dumping money I simply don't have into this pos audi.

Car headlights periodically flicker and turn off under normal conditions. Driver side flickers on acceleration and passenger side will flicker and turn off completely during acceleration or braking. Have to switch the headlights completely off and back on for them to light up again. I have the bi-xenon hid adaptive headlights factory installed on my car. I just received a class action lawsuit letter describing reimbursements for class members who have either repaired or had an authorized audi dealership document the issue within the 5 year/50,000 mile warranty from date of original purchase or lease. I bought my car at 51,xxx miles and am out of warranty with no access to the previous owners records. This is a safety issue that should be identified and a full recall campaign should be initialized with audi of america (aoa). From what I have gathered on the internet, there are 100's if not 1000's of a4's having this problem but aoa refuses to take responsibility for it and claim the headlights are operating normally. Normally is not turning off while driving on their own. I have dealt with this issue for 5 years that I have owned my car and never asked the dealership for a repair due to it being out of warranty and is expensive ($1000+). It's time for aoa to own up to this issue and repair it free of charge for it's customers since it's a safety issue.

Repeated headlamp failure.

Problem of "dipped" headlight on my 2005.5 a4 b7. Purchased the car used in 2009 and have had this issue since purchase. Asked mechanics to investigate but had found nothing wrong. Usually it was just one side, either left or right (both have occurred multiple times). The other day was the third or fourth instance where both sides threw the "dipped" error, leaving me barreling down the highway at 75mph with no lights. While power cycling them usually brings them back, this is completely dangerous and unacceptable behavior for a vehicle that is allegedly working properly. It is clear to me, as an engineer myself, that this is a gross short-coming in design of the electrical system used to drive the lights. Either the wiring, or ballasts are malfunctioning. Audi has done nothing to ameliorate or warn me of this issue.
