Mein Auto: 2002 530i
One more SoCal data set

--------------------------------------
- Southern California (+moulin), 2002 530i 5-spd 105K
--------------------------------------
HYDROCARBONS:
- 15mph (1540 rpm): +moulin: 0 ppm (limit = 51 ppm, avg = 4 ppm), PASS
- 25mph (1717 rpm): +moulin: 0 ppm (limit = 35 ppm, avg = 4 ppm), PASS

--------------------------------------
Carbon Monoxide:
- 15mph (1540 rpm): +moulin: 0.00% (limit = 0.48%, avg = 0.01%), PASS
- 25mph (1717 rpm): +moulin: 0.00% (limit = 0.46%, avg = 0.01%), PASS
--------------------------------------
Carbon Dioxide:
- 15mph (1540 rpm): +moulin: 15.0% (no limit provided)
- 25mph (1717 rpm): +moulin: 15.0% (no limit provided)
--------------------------------------
Nitrogen Oxides:
- 15mph (1540 rpm): +moulin: 3 ppm (limit = 419 ppm, avg = 16 ppm), PASS
- 25mph (1717 rpm): +moulin: 5 ppm (limit = 706 ppm, avg = 18 ppm), PASS
--------------------------------------
Oxygen:
- 15mph (1540 rpm): +moulin: 0.0% (no limit provided)
- 25mph (1717 rpm): +moulin: 0.0% (no limit provided)

This was the test results I got when I purchased the car a couple of weeks ago. Looked pretty clean for an 8-year old car with 105k. Hopefully it will turn out to be a good purchase.

btw. the oxygen is indeed measured in the exhaust. It is an indication that your O2 sensors are working correctly to create the correct stoichiometric ratio of fuel and air for complete combustion.
