I recently bought my audi and throughout the summer it drove just fine, but once winter came around and the temperatures dropped, I noticed the smell of gas in my car as soon as it was started. I opened the hood and there was gas spraying from what looked like all six fuel injectors. So I took the car to a mechanic, where they replaced numerous things (fuel pressure regulator, o rings, valve system, and all 6 fuel injectors) all to no avail. Nobody can tell me what is wrong, nobody knows. I called audi and they told me I could take it to a dealership but that they couldn't promise they can fix the car. I can't drive the car, it is a safety hazard. I have looked on many forums and there have been a few other people with the same problem but nobody can figure out what is wrong. Is there a recall, or any information you can give as to how to fix this problem??

The audi was stopped at a stop light when the RPM meter started to drop revs suddenly. Once the car was in motion the engine felt rough. The car was driven 3 miles with no further incidence and was parked for the night. The next day when the car was started in the morning the check engine light came on and the engine started to get very sluggish and shuddering. The car was immediately stopped and the diagnostic codes were pulled. The codes showed multiple cylinder misfires with specific misfires in cylinder 2 and three. The car was towed to an audi dealer where this was confirmed. The dealership mentioned that there was a voluntary recall for exactly this issue. This is a safety issue.

This car has been great to me. Aside from a fuel pump going, just recently I was driving on the freeway and the car died. The epc light on the dash popped up and luckily I was able to coast to the side of the road. I attempted to start the car several times before calling aaa (15-20 min) while on the phone with aaa I attempted to start the car again and it fired right up. Thinking it was just a one time issue I got back on the freeway where 10 mile or so later same the same thing happened. Another 20 min of waiting before it cranked again at this point I was in a b ad area with my family and everyone was getting nervous. After it started the epc light stayed on this time and I experienced loss of power and the car coughed and stumbled terribly when I needed it most. I managed to make it home and let the car sit for a day. Hoped in and it cranked right up. No problems 15 miles later it happened again. After talking with other valued audi owners and looking over the audi owner forums. I have found this to be a quite common problem with the audi across the range of there a series from 1997-2011. Please help!

My check engine light is marking misfire but I have gotten a complete tune-up, changed all 6 coils on the engine changed all the spark plugs, I've done everything possible and changed everything I can that has to do with the engine all brand new and nothing has worked and its still saying misfire...I've googled this problem for audi's and there were so many people complaining about the same thing... Also, I am having a problem with the electrical system as well one day my windows work the next it doesn't sometimes my lights will work and sometimes it doesn't, sometimes my radio will work some times it doesn't, the information on my dash sometimes doesn't light up and I can't see anything at night time, I have constantly been to the mechanics trying to figure out what's going on but we can't find the problem, I've spent so much money on this car trying to fix the problems but its really making it hard for me to keep spending money on my car and not being able to figure out what's wrong with it. This is very dangerous because if I'm driving at night time and my lights end up not working I can cause a very big accident I am very very concerned about these defects, my safety and others safety and would really appreciate if you can please investigate this problem because its happened to so many people. I also think something is wrong with the fuel system I'll put $60 in gas and two days later it'll almost mark empty I really don't understand how that is possible but if there's an answer I would really want to know. Thank you so much and I really appreciate your time.
