It's a Beru plug and glowing at the base of the tip and not the end - see picture - so when you look down the injector hole you see no glowing tip. I suspect its not effective anymore as the car suddenly battled to start . I only visually checked glowplugs as I was about to reinsert the injectors after having done a compression check. I also changed delivery valves on the pump from another one as I thought perhaps they were leaking .
