Title: Which bar oil pressure switch, mk2 16v 1991 model
Post by: walchy01 on 27 May 2010, 12:15

Hi there

could anyone advise me bar pressure switch I need as the dealer is showing 4 options, the one I have picked up is 0.15 to 0.35 pressure switch, us this correct for my car, looks completely different from the one I'm changing it for in size terms.

Thank you

depends which switch you need to replace! blue or brown is for the low pressure 0.3bar, white is 1.8 bar high pressure

it will display --- till the oil temp gets to around 50 degrees. to check if its trhe sensor at fault earth the wire, it should read about 150degrees on the MFA

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....

(http://i676.photobucket.com/albums/vv124/Baz3230/IMG_0434.jpg)

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
