I was driving along and noticed that my heater was not blowing any hot air, infact not blowing at all. Seemed like my heated seats were not working either. I also spotted from my polar FIS readout that oil temperature was high as hell and oil level at zero. I stopped and restarted the engine, I got "Oil sensor workshop!" note on my display. Car had oil and drove fine so I wasnt too worried. I came home and scanned it. There were a few faults found from sensors. I started measuring the fuses one by one, and bingo.. the number 5 (small 5A) was burned out. I replaced it and hey hou, everything's fine again.. I wonder why it burned out in the first place?
