[A4] Repair or walk away - advice for an Oil Sludge victim?

[John S. Lagnese]

Would that be safe in my  90,000 mile 91 200 TQ 20V? The oil pressure 
warning comes on occasionally. I have 4.5 bar of pressure. I would like to 
make sure that everything inside the engine is clean. Would using an engine 
flush while idling be too risky?
