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

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.

At 47658 miles check engine light came on dealer stated it was the camshaft & repaired at cost of $2007. (2/14) and same problem again at 60,711 miles at cost of $2305. There was a camshaft warranty extension (recall) for 10 yrs. 100,000 miles for same car for 2005 to 2007. My 2008 car was purchased 10/07 & would assume mfg. In 2007 which was the time period the camshaft problem existed and covered under that warranty. It appears audi did not want to extend that warranty into the next year even though the camshaft problem still existed. The camshaft should never have to replaced at such low mileage once much less twice on a much less expensive car much less than an audi. This is my third audi and I have never had a problem before. To date I have spent $4300 in 2 years on something that should not have to be replaced. Your thoughts and assistance would be greatly appreciated.

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."

I just purchased an 08 audi a4 3.2l cabriolet almost 2 months ago with 16k miles on it. After 3 weeks, and approximately 800 miles later, my check engine light came on. I took it to the used car dealership I bought it from (mazda) and was sent to audi. I took it to audi and they couldn't get me in for 1.5 weeks. I finally got it in, and they said they cleaned my valves and changed 3 injectors due to a carbon build up. 2 1/2 weeks later, light is back on. I called the audi dealership, can't see me for another 2 weeks! I did some research and found a full thread of a lot of complaints about this same issue for this year/engine size from audi and vw. Audi is claiming there is no issue and the gasoline is at fault. I use only top tier gasoline as recommended. Please review the several other complainants on this forum at http://www.audiforums.com/forum/showthread.php?t=113568 this is an ongoing issue that is being ignored and affecting a lot of consumers. It has yet to become a safety issue, but could in the very near future if not corrected.
