oil pressure sensor, clio 16v

[dannyb1986]

I have an oil leak on my clio 16v, goin to have a look at weekend, been told on here it could be the oil pressure sender loose, its coming from under the exhaust manifold and is dripping onto the offside driveshaft, were is the oil pressure sender and what am i exactly looking for? is it easier to do from underneath or above? plus my oil pressure dial isnt working, so this is making me think it could be like this!!
