Allright, I've searched the forums and I haven't been able to find anything that matches the three issues I've got, and I'm hoping you experts out there can help me. First, the basics. 2001.5 Immola S4 that I'm in love with. 75K miles all stock (I bought it CPO from Audi with 42K miles).

Occasionally at very low speeds (>5mph) I notice a very light vibration in the whole car. This is usually induced by braking (although this might not be the cause, but I'm usually braking to get to the >5mph kinds of speeds ), but continues after I let off the brake petal. It will go away after a couple of seconds, but i can get it to continue if I'm on a slight downhill. Hot or cold doesn't seem to have anything to do with it, both in terms of engine temp or ambient temp. Any thoughts? It's actually continued on and off for quite a few months now, and it hasn't gotten better or worse.
Now, I'm not sure if they're related, but I also notice the occasional rough idle. I'll be sitting at a dead stop and I'll notice another kind of slight vibration. If I barely touch the gas to bump idle up to ~1000 RPM, it goes away.
Next, I've got an occasional problem with the clutch. Again, outside or engine temperature doesn't seem to have anything to do with it, but when it happens, I get a "click" about halfway through the clutch throw. It doesn't stay there for long and it comes and goes. It too has existed for a couple of months without getting better or worse - it's just there.

Any help you guys could provide would be extremely appreciated! Thanks.
