And... mine failed (passive tank level sensor). When the tank is full I get no CEL. When the tank is low I get a CEL.
Member PIXLFIX over on Bimmerfest repaired their failed active tank level sensor by adding resistance between the two leads of the sensor. I will likely do the same if I can't find a cheap secondhand tank or sensor to swap in.
