| My daughter was driving her 2004 audi a4 at about 40 miles per hour when the the car jerked, she then pulled up to the stop light and stoped. the car stalled and would not start. the engine warning light was on. we pushed the car out of the lane of traffic. a few hours later we went back to the car and it started up with no problem, we drove the car with no problems. this is a very dangerous situation and it appears that other owners have had this problem. there was an investigation pe08027 opened on this issue in 2008 and closed in 2008 without a recall. | |||

| 2004 audi a4 1.8t engine sludge--complete engine failure. audi absurdly refuses to honor their own extended warranty on the basis the car was run without oil. the engine failed internally because there was and is sludge blocking lubrication ports to the moving parts, i.e., failure. this is my executive synopsis, but i have volumes of supporting evidence, unbelievable as it is to think this could happen in america. | |||

| I have owned my 2004 audi a4 1.8t quattro for four years. the problem that i am having is a massive issue that hundreds if not thousands of other b6 platform owners also have, the water pump in our vehicles is very prone to failure. the water pump found in our us market vehicles has a plastic impeller that is known to snap, crack, or leak causing the part to fail. i have had two of these pumps fail in the past two years. the first one failed at around 74k in july of 2008 when the part was nearing it's replacement date. the second failure occurred in january 2010 at roughly 98k miles. so i have had two failures in a very short time period. now audi is fully aware of this but has never had a recall or even acknowledges that it is their fault for releasing a poorly designed part. when a pump fails it usually goes very quickly. in my case it leaked and then i lost ac compression. i am lucky that i know cars and knew to immediately park the car and get it into the shop. i know that many other people have had significant engine damage because the failed pump caused overheating. the pump is also part of the whole system that drives the timing belt so a failure could also cause catastrophic engine failure if that belt seizes up. overall it is a huge problem and each time a pump needs to be replaced the entire timing belt service needs to be performed which runs about $1700.00 at a dealership and around $800-$1500 at independent shops. i feel that this is very unfair to us as owners, but that it also puts the public at great risk if a failure occurs at highway speeds or in traffic. lives are already at risk enough on our highways and the last thing that i want to do is cause bodily harm or property damage because a company released a poorly designed part and did nothing to improve it. i request that the nhtsa look into this issue. if you search sites like audiworld.com and audizine.com you will find lots of information and first hand accounts. *tr | |||

| I have a 2004 audi a4 1.8t. this exact model is what is described in the audi manufacturer's 8 year extended warranty for engines. i am currently being denied warranty coverage for the engine sludge that has built up in the engine. the reason being according to university audi in seattle, is that: my car is too new. but it is a 2004, the cut off year for the extended warranty. *tr | |||

| Engine has an repeated but intermittent loss of power. usually occurs shortly after starting the car and before the temperature gage shows the engine running at normal temp. engine continues to run, but when pressing gas pedal all the way to the floor, there is insufficient power to move the car. also, when in neutral or park, rpm barely goes above 1500 when pedal fully depressed. after waiting a few seconds for sometimes as long as a minute, engine will regain power and will then operate normally. this has happened at least 10 times from oct07 (when purchased car used) through 22 april. manufacturer technician is unable to locate problem. *tr | |||

| Car is 2004 audi a4 with 1.8 engine and cvt transmission. car's engine will upon acceleration from standstill, often hesitate and stumble. at times when making a left hand turn across traffic from standstill, it will at times not only hesitate, but actually stall or have a no power situation for a couple of seconds. this has led to several near accidents. i have reported to our audi dealers service department a number of time. each time, they merely say that they cannot find the problem and return auto to us. a couple of times they have said that they have downloaded software fixes to the automobiles ecm(computer). *tr (excerpt from e-mail 4-1-08) i was then told by one service rep that he had seen this problem on those audi's that are equipped with the so called cvt transmission before but that audi has been unable to address. he said that he applied a software fix to the auto's electronic management computer, but this did not help. *smch | |||
