Hi all, great forum, I'm new to the site. I am looking to upgrade to a 2003-04 RS6. Went to look at the first one in Minneapolis, MN at Carousel Audi. 2003 carbon fibre trim, sound enhancing exhaust, warm weather package, after market radio. This vehicle is on autotrader.com. Salesman indicated 1 owner purchased from this dealership and when I sat down with him, the car has had multiple owners from multiple states. He indicated that the vehicle was ran through shop and inspected. Upon road test and my inspection, I found the trans slipping, brakes having only 10% remaining life, vehicle condition 6/10. Salesman was completely misleading about the car's history and also said there was nothing wrong with the trans. Did not bring my vagcom to check codes but found it was odd that the check engine didn't come on when the vehicle was being road tested and the slipping was occurring under load. He insisted that the car was ran through the shop and the tech said there was nothing wrong with the trans. Is it common for the trans to slip without turning the check engine light on?
