going to a thicker oil will mask the problem but it can also cause oil consumption,carbon build up,and even premature engine wear,rather than hidding the problem i would recommend fixing it. the spec for oil pressure at idle and normal opperating temp is .5 bar which is a little over 7 psi (not much) but that is the spec. the best solution would be to check it by taking out the oil pressure switch and finding an adapter to check it there. rather than bore you by rambling on i will tell you the most common problem that everyone has overlooked if its not the pressure switch and i doubt its the harness because problem only happens with warm engine at idle i would replace the oil filter housing. it has a pressure regulator incorporated in it that cant be replaced separatly and i have fixed this problem with this repair numerous times
