best thing I can suggest is drive down there and while your there take it out and compare, be sure to take some coth or something to put around the area though. When doing mine I got 3 different ones from ecp before I got the right one :P

the 2 sensors on your car are blue and white, black & green are both wrong. blue is 0.3bar, white is 1.8bar. the blue sensor may be brown, but normally on mk3s they're blue

blue/brown 0.3bar one is on the side of the head, white 1.8 bar is on the oil filter housing. there is also a smaller white oil temp sensor for the mfa on the filter houisng. side of head sensor has a blue/black wire, filter houisng has a yellow wire and the oil temp sensor wire is green/black
