2021 I brought an Audi A4 Quattro 2.0 2008 after having a test drive and haven't looked over the mechanic just said it was the fuel pressure high pressure sensor that was not a big deal after an hour buying it it took it to see my mom and it quit on me I had to have it towed home it would not start I took it to the mechanic and the mechanic said the same thing that it was a high pressure fuel pressure sensor so I purchased one and put on it couple months later it did the same thing the check engine light came on and it was told it was fuel pressure high pressure sensor again so I changed a fuel sensor two fuel pumps in the engine to electrical fuel pumps in the back four sensors camshaft sensor the cam follower PPC valves body throttle can follower engine light still comes on the car does not want to seem like it wants to accelerate when it gets to the normal temperature save your driving for 10 or 15 minutes still normal temperature not the radio the temperature it will start to cut off the RPM drops very fast I also have put in a fuel pressure regulator and a fuel pressure filter just the other day it came out again saying the same thing p0089 Dakota's always been throwing ever since I brought the car and p 02993 it says performance one and performance too I have put a lot of money in to get in this car fixed in the I believe there is something wrong with with the fuel system in the cars they need to be on a recall

On 7/2/18 I merged on to 280 S from moorpark avenue in san jose. I had driven about a mile @ 60 (I do not use cruise control) when engine started to accelerate unexpectedly. I stepped on brake which slowed my vehicle but when I removed foot from brake it started to accelerate again. I was able to exit freeway safely and pull over into an empty parking lot. When I turned off engine I believe I hear a loud "roar" noise. Experience was frightening. I was afraid I would lose control of vehicle and cause major injury. I checked floor mat and floor to see if there was obstruction but there was none. I called tow company but after waiting 3 hours for C&M towing to not show up I decided to driver car around parking lot to see how it would drive. It drove fine so I drove home on surface streets. The next day took 2008 Audi A4 with 64K miles in to our mechanic. Diagnostics did not show any error codes.I do not know what caused sudden acceleration. Still I need to report this for the public record, in the event this happens again to me or others and it does not end well. Linda

Power train problem results in prnds light flashing, intermittently. While driving, the transmission changes gears which leads to loss of control of vehicle. Similar problem led to recall of previous models. Audi should be responsible for remedying this dangerous situation.

Takata recall

My A4 randomly switches into neutral as I am driving down the highway. I have no control and have coasted to the shoulder of the road on one occasion when "drive" would not re-engage. My dashboard screen flashes over the prnd transmission indicators. The check engine light is on also, so I took the car to the Audi dealer in South orlando. I was told that the transmission control module has gone bad and will cost $3100 to repair. The car also will not go into reverse about every 3rd or 4th time I select this gear. My research shows that this same problem was a recall on 2004-2006 models, so I would assume Audi will recall this model year as well. My A4 has 62,000 miles on it and has been maintained by the dealer since new. I don't understand how this safety issue has not been elevated to a recall status already given the previous history of similar problems on the same models.

It happens when I turn the car on and I go to park it. When I pass reverse. It seems to happen a lot more often after it rains. My transmission is going into limp mode due to a major fault. Code P0706: Transmission range sensor circuit range/performance the transmission range sensor tells the tcm the position of the gear lever. It also contains a neutral safety switch, which ensures that you can only start your car in neutral or park. Potential causes for this code to set are: Faulty transmission range sensor misadjusted transmission range sensor open or shorted transmission range sensor harness faulty PCM it happens to a lot of the A4 Audi's. its dangerous and its not anything that owners of the Audi did or did not do. I have never neglected my car. It is something that is enevatable because it was caused during the manufacturing.

I was driving on rout 62 with my 16 year old niece and my car felt like it went into neutral, the lights on the dash started flashing. The brake pedal felt tight but I was able to pull over without causing an accident. It keeps happening and I am afraid to drive. (especially knowing there is an open recall because my airbags may not work or worse, cause severe injury due to metal shrapnel) I also read that my car has a hidden defect that the timing chain can go at any time, causing catastrophic engine failure. I brought it to an independent Volkswagen Audi mechanic where they did a diagnostic. He told me to bring it to someplace that specializes in transmissions.I looked in my owners manual and under transmissions. It says if this happens drive it to your nearest Audi shop. I emailed Audi because I read that there were recalls and technical service bulletins about the diagnostic code P0606. I saw that there are many class action lawsuits and complaints all about the same problem with my car. I can't wait years for a class action lawsuit. I live in new england and it's getting cold. This is my only car. I bought 6 months ago, in November. I have done all the service and maintenance recommended by Audi. What ever it is that is wrong with my car, Audi has fixed other cars but not fixing mine and my car. I take excellent care of my car, inside and out. It has been serviced at every recommend milage date. Nothing has ever gone neglected. My car is completely inoperable and it is due to defects that were made during manufacturing. I do not trust Audi customer service or the Audi service center.

The park, reverse, neutral, drive display flashes which indicates that the vehicle is running in caution mode. The vehicle does not run in reverse and while the vehicle is moving it seems as if it wants to change gears such as from drive to neutral. My research indicates that this was a common problem with the 2008 models. My research also indicates that the problem is the transmission control module. I am not aware if this problem affected other year models or if Audi corrected the problem after 2008. I purchased the vehicle in July of 2016 with the problem and the dealership informed me that it was a recall problem. When I recently took the vehicle to a Audi dealership they informed me that it was not a recall problem. The dealership information sounds false since this is a safety issue. I am making this complaint to see if an investigation is warranted for me and other owners of the 2008 Audi A4.

Transmission shifting out of control.

When coming to a complete stop, the car shudders while going into 2nd and 1st gear as if someone has just rear ended the car. Took the Audi to an authorized dealer in my area and findings are that it is the mechatronic that is defective. Finding is that is a very common problem and Audi is not taking any action after contacting aoa. Repair cost is $2700.

Accelerator pedal stuck at wide open throttle. Had to shut the ignition off and pull over and restart the car and it went back to normal. Googled the net and found that many people encountered the same problem.
