I just purchased a 2005 audi a4 2.0 turbo cvt, 2 wheel drive, it's used, but has only 5000 miles on it...seems to be in good condition, but when i drove it off the lot, i heard a noise coming from the transmission from the low gears on automatic and on teptronics. The dealership said they'd check it out but that it's normal and that all the audi's of this model have the same noise...wondering if this is true? is it normal? please help. thank u
