97 A3 1.8T Lost oil pressure last week, turned out to be the oil pressure relief valve which opened and jammed. Made a claim on my AA warranty which was refused. AA state this is a known problem. Audi customer service, and two Audi dealers deny this. Can't find any mention of this fault in various forums/websites, which suggests the problem isn't as well known as the AA claim. Does anyone know the truth?
