I must admit, I hate idiot lights! But the dang thing goes on, then goes off with no rhyme or reason. My wife's plus 8 simply comes on when you first fill the gas tank after a reset.

Checked the plug gap.... 0.22 (factory spec)
Oil...... level okay
battery..... 14.6 (or so)
M3W running.... just fine
Gas..... 93 octane (US)
Oil light..... not on
