It does sound like the low pressure warning switch is faulty....
this is down by the oil filer and easy to replace. There could be two, one that is rated to come on at about .7 bar and the other at about 2 bar. The idea being that the lower one is for monitoring pressure at idle and the other is monitored above 2000 rpm. This means that the pressure must be at leats .7 when below 2000 rpm and at least 2 bar when above 2000 rpm. The warning system changes over automatically when you go above 2000 rpm.
Try and notice what engine speed does the warning come on at?
