I was involved in a passenger side impact accident where the passenger side curtain did not deploy. The impacting vehicle was traveling above 35MPH when it struck. There were no skid marks nor any attempt to slow the vehicle before impact. Both vehicles were totaled in the collision. All passengers in both vehicles (1 driver/ 1 passenger) were transported to the hospital for injuries. The vehicle is currently located at iaai in baltimore. [link removed]

Tl* the contact owns a 2008 audi a6. When the vehicle was started in the driveway, a wobbling sound was heard. The vehicle shook violently and smoke emerged from the tail pipe. Also, the temperature gauge started to rise and oil started to flow backwards to the top reservoirs. The vehicle was turned off. The dealer (audi bedford in bedford, ohio) had the vehicle towed to their facility for diagnostic testing. The dealer diagnosed that the engine was working to standards.

My wife and child were driving through the desert in arizona when our audi's driver-side xenon headlight failed. Then again 2 months later, driving with my wife and child through california the passenger-side headlight failed. Both times I was told it was the bulb. But we couldn't simply buy a new bulb. Audi needs to order it and take off the bumper to replace them. About a month later, driving through the arizona desert with my family, the driver-side light went out again.

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.
