    Replace your oil pump pressure relief spring with a new one and your problem will probably go away. The work is well documented in these hallowed halls somewhere, or likely in the HOW. EDIT: actually in this very thread; page 1. It's super fiddly, but it can be done without even draining the oil. Replacing the spring and switching to 10W50 oil fixed my identical issue completely.

    Spring part number is: "60038026000 CONTROL SPRING LC8 3,5 BAR"

    I remember there was somenone who reported flickering oil pressure warning and low pressure when he measured the pressure as per manual. In the end that was caused by an internal oil jet that was unscrewed, and that caused the pressure drop :hack

    Hope that this is not your case, and you should probably start first by replacing the oil pump relief spring.
