Technical Panda twinAir oil pressure switch?

[euroben]

Right think it's all fixed, it was the oil switch not earthing with the engine. Because of the plastic oil filter housing it relies on a small piece of metal that's under the oil pressure switch and contacts one of the bolts that holds the housing to the block, there must of been some corrosion so cleaned it up and now the lights gone out Happy days thanks for all the help

What is the best way to access this? I looked from the engine bay but can’t really see from above. Is it reachable from underneath?

Did you access from underneath to get such a clear view. I can’t really see mine from above
