Hi Guys

My fatehers '99 A6 2.8 Quattro Tiptronic started making the loudest, weirdest noise, sounds like metal scraping and it gets worse when you rev the car. Does not give any faultcodes at Audi workshop. Started leaking engine oil at the same time the noise started. Seems like the oilleak is from between the engine and gearbox. My father has removed the engine and gearbox and seperated the 2.

Does anyone know how to remove the torque converter on this model, or have had similar problems with the audi? Any help would be greatly appreciated....
