it's oily i think, a friend had a look, he suggested it might be the head gasket. i haven't been driving it much so i've hopefully caught it early enough. i think im going to have to get an Audi main dealer to do it, ive had too many problems with incompetent local mechanics...which leads me to another issue. i had a brand new clutch: clutch plates, fly wheel, and master and slave cylinders. since then, if i press the clutch pedal in lightly, the pedal just disappears to the floor, and i have to manually pull it back up again. the fluid has been bled a few times, but i have a feeling they havent pressure-flushed it which i have a feeling needs to be done. any ideas on this?
