I went and looked at your old posting on checking fule usage by doing the temp button and pushing 1000 and 10 and then the 1 three times. Worked like a charm! So here are my numbers: At 72 Degrees it's running at 3.1-3.4. So my question is what is the norm for a V12? At what number do you suspect the O2 sensor, etc.... Thanks in advance! Henry 89 750iL 170K
