Off stands and drive around to try and reset the oil sensor. Back on stands Today I drained it an it gave me 7.7l ( I forgot to warm up car before as I was rushing. ) I put 7.7 back in. New Sensor reads still low. Thoughts, just low on oil? No this isn't my first time working on cars but at this point I'm feeling a bit lost.

With this new information we are back to this part -> Give it sometime to recalibrate. It can take as many as up to 5 driving cycles for the reading to stabilize. At the moment you know the engine has enough oil in it (9L) even if the DME has not fully learned that fact yet. Try to do nothing to any of the system except for using the BC stalk to get a quick hot reading while driving and the car is at normal operating temperature. Do this for at least 5 longer driving cycles before worrying. Scroll through the BC stalk options until you get to the oil level option, and then hold the BC stalk button for 2 secs to engage the quick oil level read cycle. Do not add anymore oil - yet. IF I'm following the math correctly - 7.7L are in the engine, and 1.3L are in the oil cooler, oil cooler lines, and oil filter housing (7.7L + 1.3L = 9L mentioned in an earlier post above). While waiting for the system to recalibrate I advise against red lining the car. Try to keep the RPMs below the 5400RPM break in rev limit recommendation until the system and sensor become calibrated and stable using the process described above. PS: Leaving the car for a month without being on a battery tender may have caused some issues with stored values (adaptations) within the DME memory.
