I just recently bought this S5, 70k miles, manual, with the issue that it won’t drive. The engine will fire up, and from neutral, it will not engage any gear. If I push it hard enough 1st gear will grind. Now, if the car is off, and I throw it into gear, press the clutch all the way down, and start it, the car will jolt forward as if the clutch was not depressed! I kind of have an idea of what can be the issue, but anyone whom might have some more experience with issues like this that can give me some pointers, would be greatly appreciated!
