LEAKING OIL AT TOP OF ENGINE ON A PLUG BOLT?

2001 Renault Clio • 93,000 miles

On the engine looking from under bonnet, behind oil filler cap, thers a black plastic square with a cable attached, and the bolt that screws into engine the oil is coming from there? What is that? I thought it was oil pressure switch but pics look different to what I can see, thanks in advance

I don't have any information on your vehicle but based on the wire attached to it, it most likely is a sensor and if you remove the bolt and take the sensor out, you should see an O-ring which should be bad and causing the oil leak.
