Hi everyone,

I noticed something in my B8 2009 A4 2.0T quattro with tiptronic.
When I have the manual mode and floor the gas, it suddenly knocks/hits when downshifting. It kind of makes sense because it downshifts to give more power, but the downshift is not smooth at all.. In fact, it kinda hits/knocks... It also happens in my friend's 2013 A5 2.0T turbo 8-speed. Is it normal, or is it a sign that we should do maintenance in the transmission?

Thanks!
