Hi Bob,
"As an experiment, I fastened a strong magnet to the plastic dipstick of the PS pump in our 940 at 140k mi. To my knowledge that fluid has never been flushed, but still looked clear and red. After 60k mi, the magnet still did not have a single visible particle on it."
You know Bob, I did the same thing, but after some 20 or 30K, I pulled the magnet out and although there was no specks I could discern, when I rubbed the magnet, I got some black sludge off it. You may want to give that a try and see what you've got.
Marty
