Oil Pressure sensor self change on Ducato multijet 2/ 2017?

[Birty]

Anyone actually done this. Intermittent amber fault light on dash. I can just about get to it to clean/check the terminals but its awkward as its low down and up the back of the starter motor. Ramps would help...Got to be done from below.
Also should you drain the oil first? Fiat dealers just won't answer the phones or have closed down.. SE UK but struggling to find someone to do it, hence my question.

Not familiar with your van, but generally the oil pressure light is usually a red light on the dash, which goes out shortly after the engine is started ?
If you do choose to change it, you won't need to drain the oil as the switch is well above the sump level, but you probably will get a trickle of oil come out.
