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 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!.
Was changing lanes and when trying to accelerate the car would barely move then in an instant went extremely fast. I hit the brakes but the car was rev'd so high and going so fast that I just skidded into traffic. Before the incident we noticed it would do it but the lag wasn't so bad. . . Wasn't until we drove it on the freeway in stop and go traffic that it really became a problem. Very scary to have a car full of kids and not be able to control the acceleration.
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.
