Thanks. Looking at the site and I cannot say it gives me great confidence. It just comes off like a cheap scam. Very little information. They also don't show a Q7 past 2010. I appreciate that folks here say it works but man it is hard to get over how "scammy" the site looks.

I took some additional time to find various postings and I can see that this isn't a scam but rather a way essentially to make the car think you pressed the pedal further than you did. Question for those that have it, how does this product differ from putting the Q7 in "sports mode"?

You must have had a granny driver as previous owner. I do not feel any hesitation off the line in D. Did you try the S mode yet? I suspect a reset of the TCU will let you start from scratch learning mode.

Brand new with only a few miles on it, so no granny driver.

I need to play around with S more in comparison to D when I next get a chance to drive it.

After getting a chance to play with it, S mode does correct the problem. Unfortunately there is a gas penalty for using it and I don't think you should have endure that just to get rid of the initial delay.

Or maybe the logic in the D mode is to start out slow to save gas? I really do not see any delay or hesitation in D mode, so I am not sure what you are noticing. However, when I want to really drive this machine, S mode definitely kicks some butt.

When at a stop if you press the accelerator slightly the car doesn't start to move. You actually start to move your body but the car isn't going. It's an odd feeling. I believe the issue is that the pedal doesn't really engage until it is pressed further whereas in "S" mode it goes right away. S mode also revs higher so it is going to use more gas. I shouldn't need S just to have the car start to move at the top of the pedal press.
