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

I had just put $35 in gassed the car still said I needed gas and that I had zero miles left of gas I made a trip that was about 45 miles in distance. My car was then parked and turned off for about 3 to 4 hours then it had trouble starting at first but turned on and I proceeded onto the freeway which was across the street from the parking lot I parked inside of. It was about 9:00 pm and thankfully there was not a lot of cars out. The entrance of this freeway consist of one medium sized steep hill which remains traveling upward onto a mountain when my car suddenly shut off my 3 year old daughter and I were in the car and thankfully we were on the last lane due to the fact that we were barely entering the freeway. I parked on the right side skirt I had just replaced that battery earlier that week (no more than 5 day before). I had a small gas can in my trunk and had someone go to the gas station and bring me the gallon of gas which I emptied into my car and it turned on. At times the car does smell like gasoline especially if I just put gas. It doesn't matter how much gas I fill up my tank with it will indicate I have 0 miles of gas in the screen and the fuel gauge will not go below the middle indicator and will never show above 3/4 full. My tpmsa is always indicating a problem when the I have a mechanic see it and he assured me it's in good condition

I have had repeated issues with oil consumption. Oil overconsumption has been the subject of a class action lawsuit for 2009-2011 A4S. For some reason the 2008 was not included in the lawsuit. I have had to top my oil off every 3,000 miles, at a minimum, for the entire life of the vehicle. This has been a safety issue numerous times where I was not close to any facility that sold oil and was forced to drive the car on low oil a long distance in order to top it off. I have also had issues with the headlights being dipped -- also a known problem for this year and model. The headlights go out way inadvance of a normal life expectancy. Audi gives excuses on how it can be fixed (the prices and repairs were inconsistent between the two headlights). One of them they quoted me $1300! when I read the service information they had only replaced a bulb!

Problem with my vehicle is the high pressure fuel pump and camshaft. Apparently there has been a warranty for 2007 and older models and I was also told by a dealer that 2009 and new models were covered. The warranty was an extended to 10 years/120,000 miles for this issue. I called corporate also to see if there may have been a mistake at the dealer that my vehicle was not covered and they said it was not mistake. Whats astounding is that the same issue my vehicle has is what is covered in previous and later years for the exact same vehicle as mine. My mechanic advised me that the system is failing and it is only a matter of time I start experiencing loss of power and other engine issues. I don't know if I am writing this to the correct department however any assistance in making this issue known and even forcing Audi's hand to take responsibility of this issue would be greatly appreciated. The vehicle is a wonderful vehicle but to be told about and also reading about other owner's experiencing this issue and saying that their vehicle just stalled and lost complete power or that the camshaft broke into pieces causing engine failure in addition to fuel failure is scary. Again it looks like this is a big problem that has been ignored for years. Maybe forcing a recall will correct their manufacturing problem with the affected vehicles.

Initially, check engine light came on. Dealer suggested oil change well before due as solution. Problem is failing high pressure fuel pump. Failing fuel pump causes camshaft and valve lifters to wear prematurely. As high pressure fuel pump fails car loses power and/or loses ability to accelerate. Car is especially dangerous in situations such as crossing traffic, accelerating to get up to speed, may lose ability to accelerate when attempting to pass other vehicles - very unsafe on 2 lane roads. Problem of little to no acceleration is intermittent and without warning and can be frequent. Same parts and problems as documented on prior models years, including 2007 Audi A4's (previous model year) that were covered either due to recall or manufacture extending the warranty due to product defect. 2008 models were still under initial manufacturer warranty for age of vehicle when prior years became covered / recalled. Cost at Audi dealer to fix were over $1600. Dealer paperwork states problem is "not uncommon on this motor."

After reaching an appropriate speed on a highway, I eased off the gas pedal but the car continued to accelerate. I removed my foot from the gas pedal entirely but the pedal stayed down. I shifted the car into neutral, turned on my hazards and pulled over to the breakdown lane. I got out of my car and checked the still depressed pedal to see if anything was obstructing it and there was nothing. I pulled the pedal up and the engine stopped revving.
