Hi - The Crankcase Ventilation Valve Extended Warranty [XXX] covers only ten years or 120k miles. My car has close to 160k miles. According to NHTSA or Audi, -??Audi has determined that, in some vehicles, it is possible for the crankcase ventilation valve to malfunction, causing a whistling noise in the engine compartment and the MIL to illuminate due to the presence of specific fault codes caused by this component. This condition may impact the vehicle tailpipe emissions, and the presence of a MIL-on condition may cause the vehicle to fail an IM (smog) test.-?? This is causing the engine to rev on its own, foul odor, consume more oil and gas, MIL-on, and potentially cause the IM (smog) test to fail regardless of years or miles and a safety issue. Please add this matter to recall rather than extended warranty and is likely related to NHTSA Campaign Number: 22V178000 which is causing oil separator and coolant pipe issues that need to be covered.

I am having a transmission malfunction warning light on the dashboard that comes on. The car will not shift gears which is dangerous when driving in streets/highway. This is a known issue with the Audi S6 and related models and a class action lawsuit is in process. Audi is trying to charge few thousands dollars $8000-$12,000 to replace the mechatronic and clutch transmission system which is very prone to failure. Thank you

Loss of power on freeway, due to known turbo issue on these cars. Filter for turbo oil clogs, and burns the turbo's without warning causing loss of power. Not to mention it often sends metal into your engines oil and the repair for that is more than the car is worth.

This was a low mileage (9K) less than 1 year old pristine condition Audi S6. The vehicle was driven approximately 10 miles and then parked in a driveway where it was turned off. The driver sat in the vehicle for 5 minutes with the engine off prior to exiting the vehicle. Between 5 to 10 minutes after exiting the vehicle we smelled smoke in the house. We discovered the vehicle had flame and smoke emanating from under its hood. The fire department had to extinguish the flames as we were unable to do so with a garden hose. The entire front of the vehicle burned. It was classified as totaled. The vehicle was inspected by a fire cause and origin inspector and Audi. I have been told verbally that the fire likely began in some electrical components behind the driver side headlight area. Audi has confirmed that the fire was not caused by external factors but I have not been provided any other feedback from Audi as to what the actual defect. Was. Just to re-cap: 1. the ignition was off 2. the car was not running 3. the car spontaneously caught fire and was destroyed. 4. it was raining that day 5. the car was in like-new condition, well maintained and with no known defects. 6. we were lucky the car was not in the garage as the house would have caught fire.
