I don't get it either, but reading on this and other forums it is often said that IMSB problems happen more often in M96 engines that have not been driven a lot and not driven hard. Is there data to back this up? I don't know.
This is from the LN engineering site.
"Remember, not driving your car or worst yet, not driving it like Porsche intended can make the problem worse. Although a greatly debated subject, most experts agree that more frequent oil changes with a quality 5w40 motor oil like Driven DT40 every 6 months or 5,000 miles is a good first step. Secondly, actually driving your Porsche more often and avoiding higher gears to keep the revs above 2500-3000 rpm is another good step to take to improve the life of the ball-bearing in the intermediate shaft. Although there is limited data, the general trend is that lower mileage vehicles with infrequent oil changes or driven light-footed (as in run at low speed/engine rpms) are most likely to suffer a failure rather than those cars that are driven hard and well-maintained."
