Oil light is on

What is your question?

I’ve changed the oil and oil pressure sensor and checked all the wires and also checked if there’s any leak and still oil light comes on after 15-20 min driving. Any help please. At the beginning the oil light came right away after I started driving the car but after I changed the oil pressure sensor the oil light came on after driving 15-20 min

How long has your 2011 Volkswagen GTI had this problem?

I have this problem since I bought the car for almost a month
