Acceleration Stall 2016 Audi A6 3

[TallGuy]

I was going down the on-ramp to the freeway and decided to see how the car would perform if I pushed the accelerator to the floor. I felt like I was on the Millenium Falcon out of Star Wars when they first attempted to go into hyperdrive. The car just felt like it was going to stall. It did not feel like a lag. My car has 2500 miles on it, an I drive it very conservatively in Dynamic mode. I backed off the accelerator and the car seemed to have normal power for whatever gear it was in. Does the computer learn my behavior? So I hit the accelerator, and the computer goes WTF what does the driver really want. The engine had been running for 10 minutes when this happened. Do not think this is a dirty part issue. What should I expect for a full out to the floor acceleration from a rolling start. A fly by wire pause, or instantaneous acceleration. Thanks for your input.

Not really sure where to start given your long list of questions, but sounds like perhaps the transmission was trying to figure out what gear to be in, and that you didn't give it time to make its choice.

Also not sure what your expectations are, or even which engine you have (2.0T, 3.0T or TDi)?

This sounds like exactly what it was. Gearbox takes a while to figure out what you're trying to do. Any time I really want to mash it, I have to be in manual mode or have been driving pretty aggressively in S for a while.

It is a 3.0, I will test out the gearbox idea. I will try the S mode as well. How long should gearbox take to figure things out 1-2 seconds? Thanks

Since the engine and transmission are both "adaptive", they react to your recent driving style. If you've been feather-footing it and suddenly start driving aggressively, the car will begin to adjust its responses accordingly, but you may not feel the difference until many minutes have elapsed and you've been up and down through the gears several times.

It's a feature of the DSG, this happened a lot on my B8 S4, one time in a intersection. Typically happens after slowing down for a right turn, then getting on the throttle - listen to the engine rev freely.. I don't expect the ZF 8HP would have this problem.

Essentially the tranny is expecting to shift at 2500 or whatever it normally shifts at so its in the process of shifting when the ecu is like "oh shit, he really wants to go. We need to be back in first" and that bogging down is the tranny beginning to shift then realizing it doesn't.

The OP's car is a 3.0T, so it has the ZF 8HP, not the DSG...

Plan to take car for a long drive on Friday. Will see what happens. Is there an easy, benign way to have the computer start over (light footed driving).
I find it troubling to think there would be a safety issue to need to accelerate quickly and have the car stall out. I am accustomed to mashing my foot on an accelerator and have instantaneous response.
Thanks for your input.

Yeah the A6 3.0T has the ZF 8HP planetary transmission, which should not be having this problem, unless it has faulty programming. It should not need the same setup time as the DGS, when shifting into the opposite mode (down shift instread of upshift).

Just drive aggressively for a several minutes and the computer will figure out what you're trying to do. Also keep in mind that this transmission has eight gears to choose from so the programming has lots of options (gear + throttle position + speed).

[TallGuy]

Thanks I will try that.
