I have purchased a 2002 Audi A6 2.7T from sunnyside in middleburg hts Ohio. The car had a vibration felt in the steering wheel and floorboard with oem wheels and tires. Went back and forth to this specific dealer with no results. Other area dealer, fred baker was able to alleviate the problem, but I asked if purchasing new wheels and tires would fix my problem. I was told yes, as long as I get wheel and tires with manufacturer's specs. Purchased new wheels and tires with the following specs: 5X112mm bolt pattern, wheel bore to fit hub bore of 57.1mm with hubcentric ring. The offset of the tire is 35mm (same as oem tire) and the vibration became worse. This is at highway speeds. Dealer tech manager did not even inspect the vehicle, even under warranty, just blamed the wheels and tires. Contacted the wheel seller, edgeracing in Florida and was told they build wheels for Audi and VW to specs and never had any problems before. Dealer tech manager asked me how I want to problem fixed. Manufacturer's manual does not say that I should not be upgrading my car's wheel to more than specs. My tire ratio and offset remained to manufacturer's specs, and I do not feel that my car is safe when driving on the highway. I do not have the monetary resources to inspect the car to see if it was ever involved into an accident and never reported to carfax. I have been driving for 12 years and I can differentiate between rough driving due to lower profile tires (pirelli pzero nero M/S 235/40/18) and steering wheel vibration and floor board vibration due to some mechanical problem that dealer will either not disclose or are trying to hide. They did drop the sales price from 26,995 to 23,250 when I purchased the car from them. The car is still under warranty and I have contacted the auto manufacturer in germany to inform them of the potential safety issue. Please advise me how to handle this situation, I feel that the car has a mechanical problem that the dealer is trying to hide.
