I have a 2012 A6 3.0T Prestige with Pre-Senses and Assistance package and was wondering if you guys had a "hesitation" problem with the car. I think i have narrowed it down to when trying to apply the brake and the gas at the same time. Think of it as trying to get off the line quickly or crossing a 4 lane highway and having to slow a moment then accelerate swiftly. When I am at a stop and have the brake pedal pressed and then press on the gas the rpm briefly goes up then goes back down. (two feet driving) The gas pedal feels dead or non resposive. Is this a safety feature and have you guys experienced anything like this. I know most of this can be eliminated by using only one foot but sometimes in agreesive situations you may need to use both brake and gas pedal. Thanks

Rule #1, never use both feet.

What you're mentioning is a safety precaution, the car kills off the gas line when it detects both pedals pressed for a prolonged time.

I don't race professionally, but I never heard of using both feet in an "aggressive" situation.

Stop ruining your car.

I'm sure it has to do with all those Japanese cars with their stuck throttles. I'd read that they want the drive-by-wire throttle to be cut off if the brake is depressed. I imagine there is a delay so it doesn't cut the throttle immediately when the brake is pressed. But to quote a great "Stop ruining your car".

Left foot braking is a common practice in racing, particularly with a turbocharged car. It that case, it keeps the engine revs up and the boost available at all times. Here's a link to see Walter Rohrl dancing on the three pedals of the original Quattro rally car.

On the street with fly by wire throttle systems, left foot braking leads to the strange behavior the OP pointed out.

Just use one foot, and leave left braking to the "Master".

Or Audi is remembering its mega-millions lawsuits for "unintended acceleration" back in the 1980's

Thanks guys for your comments. I was just making sure that my car wasn't the only one. And yes i thought of the unintended acceleration issues back in the 80s and hoping it was more of a safety issue. Thanks again for your feedback.

I had the same question as the OP. Thanks for sharing. I worked on a construction site as a laborer in the summer when I was a kid and was promoted to driving the forklift. The only way to drive a forklift with a heavy load is to use two feet.

You can't powerbrake any modern car that way, as soon as you touch the brake the electronics disengage the throttle.

Thanks for the replies. I had never heard of that before and it took me a while to figure out why the hesitation occurred. Keeping in mind not to use the brake pedal with the gas pedal has all but eliminated the issue.
