If a stock BMW oil pressure switch functioning correctly is flickering at idle then you have problems. Either your oil pump, mains, or big ends (or all three) are hosed or will be shortly. The switching pressure on the stock switches is only about 3 psi, so if you have less than that, your engine is devouring itself. You sure you aren't looking at the charge light?
