The Bosch Duraterm and the equivalent Beru plugs vary resistance based on temperature. They start out ~ 0.8 Ohms cold and go up to ~ 30 Ohms when hot. All the bad ones I've seen read infinite ohms and don't get hot anymore. You should have a spare glow plug in your bag of tricks. See how your meter reacts to that one and go from there.
