Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“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 same problem. This should be a federal recall. …”
NHTSA complaint #10282073, filed 2009-08, 9,892 miles“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. No fix for this and they will be charging about 1500 to clean and fix the problem temporary when the warranty expires. Second issue is with multitronic CVT. This is also their design flaw where the transmission have difficulties engaging causing severe shudder and jerking during an acceleration from stop. …”
