Hey guys proper stuck on this 2005 Audi A3 with the legendary 1.9 TDI engine. Oil pressure light came on after I did some welding to the sills and doing an oil and oil filter change. It’s always at about 1.8k revs. I thought maybe bad sensor. Changed it for a new one. Still oil pressure light comes on. I thought I had bought a bad sensor. Bought another, light still on. (These are all new sensors btw). When changing for the last sensor I took it off with the engine running and got COVERED in oil. All. Over. My. Face. This oil blew up into my face so turned the car off before engine damage. So now I know it has sufficient pressure. Topped up oil. Still oil pressure light on. I’ve taken off the oil pan and cleaned the pickup line from inside. Still light on. The plug for the pressure sensor is receiving 2.4 volts. I beg someone help me
