Filed Oct 10, 2012 · Electrical, Engine · 70,290 miles · NJ

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.

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.

I noticed a lots of white smoke coming from the exhaust system and the car was shaken really hard. I pulled over cause the check engine light came on. Then I has to get out of the road 11/15 as soon as possible so I only could drive 40 miles per hour or the car will shake more. I purchased the vehicle with a personal check. I want this vehicle back to the dealer as soon as possible. I do not want it . Can I cancel the check?

I am concerned with the safety involved with the catalytic converter on my audi a6. My check engine light appeared and I took it into my local mechanic who showed the fault as the catalytic converter. I then took my vehicle to the local audi dealer where they insisted it was the oxygen sensor. I then had this replaced and audi verified that everything was correct. Once again my check engine light appeared 200 miles later and I took the vehicle back to the audi dealer. I requested that they check the catalytic converter again and they insisted that it was once again the oxygen sensor. The warranty on this part is approaching the end. I asked, "if this is once again replaced and the light comes on again in a couple hundred miles, my warranty will be up, will you cover it? Their response was, "if it is one mile past the warranty, we don't have to cover it." from this comment one would conclude they are giving me the run around until my warranty is up so they will not be held responsible. My concern is that audi is failing to comply with a federally mandated warranty. They simply do not want to replace the converter which is placing my life in danger considering a car can catch on fire if the catalytic converter is not working properly.
