oil pressure warning. brown/blue one brings the oil light on if pressure drops below 0.3bar at idle, white one brings on buzzer and oil light if pressure drops below 1.8 bar from around 1.8-2k rpm +

Didn't want to start a new thread, but i've searched all night and cant find my answer. So i though i'd dig this one up.

Im having trouble with my oil pressure switch on my 16v. Reading RJ post about blue/brown and white makes me wonder if i have to wrong switch fitted. Heres a picture....



Ive found a brand new blue switch with loads of stuff that came with the car. Should i change the black one with the new blue one?

Any help appreciated
