Hello, I am trying to run monitors for Smog on this 2004 BMW Z4 it is not running and not setting codes. Any ideas? Thanks for the help I'll post the fix. Monitor in question is comprehensive component monitor.

Comprehensive monitor is ignored on all gasoline vehicles. Test it and it will pass.

On older BMW's and Mini's that do complete the component monitor with no codes I start looking at the electronically controlled MAP thermostat. It usually does not fails its test, but it is also not in a plausible range that the DME likes or there is no code for the failure of it. So the monitor does not switch to complete.

The fix was to go get it smogged and it passed. I went to the Bureau of auto repair website and saw that misfire fuel and CCM were not monitored for gas engines. Thanks for the advice.
