problem #2

Car did not show any signs prior to check engine light coming on. Within several minutes of check in light appearing the car begin driving rough and smoke poured from under the hood. My husband quickly cut the wires of the coil pack from the housing to prevent the fire from spreading, as I grabbed the fire extinguisher.

Extreme vibrations are occurring while vehicle is stopped and in gear. This problem has existed since I drove it off the lot new. It now has only 8000 miles. The vibration levels vary and can fluctuate. When vibrations are high the vibration is nauseating, tingles my ears, and rattles my teeth. My keys vibrate enough to produce sound and they appear blurry. My local Audi dealer says there is nothing they can do about it currently, but suggest there may be future remedies. They did tighten my seat and say that my car is operating within specifications. I drove an identical vehicle to compare from their lot and my car vibrated significantly more. These severe vibrations prompt me to place my car in neutral at traffic lights so I don't feel ill. This can be dangerous since my car may not be in gear, and if I'm distracted, then need to accelerate suddenly, I won't be able to immediately. I'm afraid I may get rear ended at one of these times. The vibrations make me feel sick and give me headaches while driving which can detract from my ability to operate the car safely.
