Something ive noticed on the Audi that ive never had on a previous car before is that when im driving normally 1/2 throttle ect its normal but if i put my foot to the floor there is a feeling of an additional button being engaged on the pedal at 100% throttle. Its hard to describe but basically when the throttle it say at 90% if you go any furhter i can feel a click. Im not sure if this is just to alert you you are at full throttle or is there another reason for this, something like... it would only fully boost when clicked in or is it just me ????
