"Jerky" Shifting

[RV8 Mike]

I've been playing with the Sport mode, and have had two incidences where, when accelerating from a stop, the car "jerked". It felt like instead of up-shifting to the next gear, it down-shifted. In accordance with the suggested break-in procedure I am trying not to "baby" it, although I am not normally an aggressive driver. Is this a quirk of the Sport mode, or am I not agressive enough, or could this possibly be a defect? The transmission is perfectly smooth in the normal mode.

i think what you are describing is normal. I've done a few thousand miles in my father's 09 Jetta DSG, and the throttle is a lot more responsive when you are on sport mode. I can easily get a 'jerk' or a 'lunge' out of the car if I'm not careful

My only complaint is first gear performance. It doesn't go right away when I push the accelerator. There's a slight delay. It's pretty annoying.

BTW yatzee, I had a 2006 Interceptor, great bikes.

Give it just a beat before you ease into the gas. My understanding is that the DSG needs that beat to realize that you are now wanting to go. I agree it is a little weird, but once you get you used to it you won't even notice.

Yeah, I figure it's something I'll get used to. My mother in law's Lexus behaves in a similar manner. On most accasions, it's not a factor, but there are times when I want instant acceleration. I'll try bumping it.

Thanks for the hints; had better luck today. I live on a hill and like using the sport mode for compression baking. I don't even touch the brakes until reaching the bottom of the hill. Works as good as the braking mode on my wife's Prius. Her brake pads look new after 95,000 miles. The Toyota dealer told me we probably would never need to replace the pads for as long as we own the car.

One thing that the DSG totally respects is the kick down switch. If you floor it and then go into the kick down detent on the accellerator pedal, the DSG may appear to be confused. In actuality, it's trying to select a different gear than it preselected on the alternate gear shaft. Once the requested gear is available, power is transfered from one shaft to another.

Ease into the power then get on it. The DSG doesn't seem to lend itself to flooring it from a stop/almost stop.

What people don't seem to realize is that the DSG starts to engage the clutch before allowing acceleration. It the slips the clutch a little as it starts to go, to keep the power application a bit smoother than a manual would.
I admit it seems a little strange for most people, but some people drive that way already. I do something similar, but a little more to the extreme. I tend to engage the clutch fully before giving throttle. It's something I was taught to do when driving big trucks. I do occasionally do the "apply throttle as you release the clutch" method, but only when I need to take off fast. Other than that it's foot off the clutch before I touch the "go" pedal.
Once you let off the brake the DSG does a slight application of the clutch to give the car a little "creep" forward, but it never fully engages the clutch until you apply some throttle.
