Volkswagen issued a detailed service bulletin regarding this.
The repair procedure includes confirming the oil pressure with an independent oil pressure gauge. This is to eliminate the possibility of an erroneous display. Has this been done?
The root causes of the failure you describe are the use of incorrect oil i.e , non synthetic , and/or the use of the wrong oil filter. Over extended oil change intervals are also a factor.
If you are having recurring problems and actually have LOW oil pressure stop driving and get it properly diagnosed and repaired.
