Have my car 3 months now (Premium Plus) and almost at 5K. Since delivery I've noticed that when stopped at a light then about to let go of the brake, It feels as if I get a grabbing/sticking sensation. It almost feels the same as a car which has auto start/stop and you get that rumble.

I've had passengers ask me the same as its not just felt through the pedal. Its as if something is keeping the car from moving when letting go of the brake for a second.

Looked around the forum and found some posts about Hill hold and its definitely not that as where I live is mostly flat and rarely stop on inclines, but who knows....it may be related to hill hold calibration sensitivity??

Any thoughts, ideas? Are others feeling this.

The Hill Hold function works thru the ABS - it is possible that a calibration or even the angle sensor is not working correctly and you're getting some 'hold' on comparatively flat surfaces. I've noticed this a few times in mine and while true, haven't really worried about it cuz as soon as I apply throttle, I still accelerate just fine. I will add that since installing the SprintBooster and now keeping it in Red all the time, this phenomenon has disappeared and even the Hill Hold is now less aggressive - meaning that as soon as I lift off the brake the car will creep forward even on a slight incline ...

Thanks Roger. I was going to mention it at my 5K. Looking around the web at other forums, I learned that Audi's implementation of this actually applies the brake and slips the tranny into neutral then re-engages it as you lift off the brake. This was on an A6 forum and really hope that inst the case with the Q3's. That sounds like a recipe for disaster and unnecessary wear on the tranny. Almost as bad as auto start/stop.

To be honest, this is a feature that I can do without and will talk to them about disabling it if it cant be re-calibrated or adjusted. With an automatic, I cant see the value. The other forums mentioned it can be checked on/off (at least on the other models).

Ralfo - I'm not sure where you found the tidbit about slipping into neutral, but I think that is WRONG dope. On the Q3 at least, HillHold merely applies the brakes once you hold firmly on the brake (for about 3 seconds) while on an 8 degree or more incline. As for Start-Stop, this feature is VERY reliable and actually wears the gearbox LESS than idling while stopped.
