At a stoplight yesterday, the cvt transmission suddenly failed. When I pressed the accelerator, the vehicle would only very slowly lurch forward with a great deal of "grinding" noise. I was barely able to limp out of the flow of traffic and then had it towed to my shop. My mechanic today told me the cvt (continuously variable transmission) failed and needs replacement. New, the part alone is $7,500, with another $1,000+ in labor. My 2003 A4 has been meticulously maintained since new and only has 75,000 miles. I have found considerable "traffic" online regarding major problems with Audi cvt - but very little on your site. This is s a major design problem that consumers should be made aware of.
