Technical Identification of sensor next to the oil filter

[xj25vm]

Fiat Ducato 2015 2.3JTD Euro 5. As per subject, I have an oil leak from what seems to be a sensor toward the bottom of the engine block, towards the driver side (UK), on the forward face of the engine block - next to the oil filter. I first assumed it is the oil pressure switch, but none of the parts I can find online seem to look like what I have in there. Does anybody know what sensor is that? Many thanks for any info

Answering my own question. After doing more research on the internet, it looks like it is the crankshaft position sensor. Doesn't seem like anyone is selling a seal for it - so either I will have to make one with RTV silicone, or replace the whole sensor.
