2011 Audi Q5 2L Turbo - Part2 - Min oil light/Add oil warning message - Replace the WHAT??

Vehicle came in with very poor running and oil consumption. See Part1:    • 2011 Audi Q5 2L Turbo - Bad misfire & burn...   For Part2 I deal with this annoying minimum oil level light on the dash. This vehicle has a dipstick. Later models just had the tube but no stick. The oil level is perfectly at max. Perhaps a faulty oil level sensor? I check the scantool and there is a PID for oil level. Thankfully they also had a PID for oil level threshold (minimum level at which it'll turn the light on). The measured oil level, as seen in the ECM, is ABOVE the threshold. So the ECM KNOWS that the oil level is GOOD... But why does that light/message keep coming on?? Google/TSBS came to the rescue on this one! The cause is so whacky there's no way you'd ever find the issue without them! Disclaimer: The information, demonstration and any content contained in this video is for informational purposes only.
