I have a 2015 Q7 3.0. I started getting an oil level senor defective error on the dash. I replaced the sensor and the error has not gone away after clearing all the codes. I checked the pins and had 12volts on I believe pin 1. Ground continuity on pin 2. And variable voltage on pin 3. just wondering if anyone has any ideas of what I can should check. I have seen mention of the hood latch but that switch seems to be working because the hood shows as closed or open appropriately. Any thoughts?
