I have 2008 audi a6 cvt (8000 miles) with 2 major issues. One of them being carbon deposit build-up on intake valve causing engine malfunction light to come up. The problem with this is caused by direct fuel injection of their engine and is common with every fsi engine as I was told.

This is also their design flaw where the transmission have...

difficulties engaging causing severe shudder and jerking during an acceleration from stop. I have difficulty controlling the throttle and if I step on the gas pedal harder, it will cause sudden acceleration and if I don't, the car will jerk back and forth and will not get decent acceleration, which is a major safety issue. Audi states that there are no complaints for this and the vehicle is running fine. I had the loaner (a4 cvt) one and the car also had the same issue, but significantly less severe. Toyota is being honest about their faults but it seems like audi is trying to hide this issue until there is a death or an injury involve, which by that time, too late. *Tr

I leased a 2008 audi a6, less then a year ago. Audi has had my car now 3 times for a problem with the intake valves and carbon deposits. They have been unable to fix the problem and refuse to admit there is a problem with the car. It has been in the shop over the past 6 months for 15 days. I have had to continue paying for the car when it is un-drivable. I also paid for audi care upfront when I leased the car, and the level of care is pathetic. On the audi forums, there are many a6 and a4 owners having the...
