Throttle response

Just trying to figure out if this is "normal", as my dealer says, or a fixable problem.

Low-speed throttle response on my 2012 DCT is poor. When starting out at a moderate pace the engine seems to bog and surge until the revs get above 2,500 or so. In addition, throttle response is far from crisp, almost seeming like the timing is retarded (for those of you old enough to remember what that feels like). Gentle or hard acceleration doesn't bring out the problem.

Premium fuel seems to help, so my theory is the engine senses pre ignition under these conditions and retards the timing accordingly. As the car is intended to run on regular gasoline I'm not thrilled about having to feed it the more expensive stuff.

Does anyone else have this problem? Thanks.

Mine is similar. You definitely can't stomp on this car and expect it to take off. The throttle response is very much like my previous car, a VW Jetta Sportwagen which had the DSG tranny, also a automatic dual clutch. A few times it scared me when I went to stomp on the gas to get out of the way and it seemed to take for ever to get going. One thing that helps, which you have to train yourself to do. With my VW and the Focus they react much better if you wait a heart beat or two before stepping on the gas after releasing the brake pedal. This give the tranny a chance to engage.

I have to remember this time to time because my "weekend" car is a Mercedes SLK. That car takes off like a bat out of hell when you hit the gas!

Yes, the car sucks at figuring out that stepping on teh gas pedal means you actually want to go.

If you gas it a little bit before you let out the clutch you'll get a little more jump off the line but it wastes gas.

i drive around town in sport mode and i find that this helps a bit w/ the bog down and delay vs. driving around in drive....not great but a bit better.

The throttle response on my car improved a great deal after I received the last tranny update more than a year ago. It actually seems very good at this time.

Around the stop and go traffic SelectShift is the only way I have found to avoid this trait in my car, but my DCT is not playing nice and I have a host of issues with it.

I have not found the DCT to be of much fuel savings for around the town traffic, it works better on the highway much like a car in overdrive mode.

Trying playing the TC off. Now, I'm back on the summer/stock COnts right now at the stock 35psi. Last few stops where I HAD to get across the street and not get hit in two directions, the car really took off. This was in Drive. I'll probably play a bit more with it this weekend :D

If not so much timing being pulled because it is sensing a knock activity, but the wheels may have JUST the slightest loss of traction and the car slows things down until traction is found again. Thoughts.

That's not going to help the OP much. He has DCT.
