Default left-foot braking?

does the s4's drive-by-wire system allow you to stay on the throttle while left foot braking?

Default Yes and No....but really No....

If you left foot brake, the DBW system will cut the throttle. Some have reported that if to brake, then gas, then brake (or something like that) it will work. The problem is that it that the throttle/brake trigger point isn't consistent, so it's not a very reliable method.

Default that's too bad...

strange that a company with such a storied history in rally racing and performance driving wouldn't let you do that. I wonder if there's a mechanical reason the computer behaves that way. Does a chip upgrade change it?

Default Chips do not fix this, unfortunately...

Well, they <b>could</b> but nobody wants to assume the liability. I'm guessing that the whole Audi 5000 issue pretty much sealed the deal for Audi.

Default It's very consistent! If you apply brakes before gas, it will work as you expect. However,

if brakes are applied AFTER throttle, the throttlw will be cut after a few seconds.

This is a safety feature.

Default Yes, but my point is....

In normal street driving this method doesn't work well at all.
