Has anyone else had this problem which seems unfixable? we first noticed oil in the coolant when the coolant warning light came on. The car went into a reputable Prosche specialist who replaced the head gaskets and heat exchanger. The heads were pressure tested and were fine. The car seemed fine for about 3 months (5000km) and then the coolant warning light came on again - Same situation - Oil in the coolant. The car went back to the same specialist, they pressure tested the heads, heat exchanger and turbos and could find no fault. They then wanted to simply replace the turbos as a bit of trial and error (Very expensive exercise). At this point I took the car back from them. I'm thinking it's a cracked block unless anyone can suggest any other possibilities.
