I have a 2011 S4 with S Tronic and 2500 miles. In manual mode, under wide open throttle, using my paddle shifters, when I shift into 2nd, it won't hold the gear to redline. It shifts between 4000 and 5000 rpm. This problem also occurs when I am in auto mode as well under wide open throttle. It seems to hold remaining gears to 6600 rpm or so--just not 2nd. The only time I have found it will stay in 2nd to redline, is when I am in manual mode M1, accelerate under wide open throttle, and never touch the paddle shifter. Then it shifts properly at near redline (6500 to 6600) in all gears, including 2nd. HELP!!
