Vito 2001 CDI 110 oil pressure sensor location

[skibidipop]

I bought old Vito MK1 110 CDI 75kW .. and I have oil light on dashboard.. When I searched for the sensor I couldn't find it, but I found the cable and the connector for it.. it was just hanging from the loom.. it is in the same loom as the oil level sensor located on the bottom of the sump.. I know this should be the connector for pressure sensor because it fits the sensor I bought
Can someone explain where is this sensor located ? I think it should be somewhere around the oil filter

Here is the picture of the connector:

I just need the location of the pressure sensor.. this should be OM611 engine .. someone must have workshop manual or something

I have only found this manual and as far as I can see, the 2.2 cdi engine doesnt even have pressure sensor, only level and temp sensor... is that correct?

also, I'm having trouble finding anything for w638 (mk1 vito) on internet, youtube, etc, why is that?
