I have a 2004 S4 Avant 6 speed. For the last few months, when I haven't driven the car for 8-12 hours, the car doesn't start right away. I thought the problem was with the clutch since that has to be depressed for the car to start. The dealer replaced the clutch switch and ignition switch to no avail. It doesn't seem like the battery is the problem as their is no sound whatsoever from the engine compartment when the car won't start to mimic a weaked or dying battery (i.e. no continuous cranking sound, etc)When the problem occurs, to get the car to start, the key has to be turned more than my wrist can rotate to the point my key on the remote snapped off. The two local dealers cant find/reproduce the problem when I have brought the car to them. Once the car does start, I can drive a couple of miles, turn the car off and it starts immediately thereafter with little effort or torquing of the key. Any ideas?
