The glow plug system has a glow plug installed in the inlet side of each cylinder. The glow plugs heat the combustion chambers before and during cranking, to aid cold starting, and after the engine starts to reduce emissions and engine noise when idling with a cold engine.
A glow plug wiring harness on each bank of glow plugs is connected to a separate relay and fusible link in the Battery
Junction Box (BJB). The individual glow plugs are grounded through their fixing in the cylinder head. Operation of the glow plug relays is controlled by the Engine Control Module (ECM), which also controls the illumination of the glow plug indicator in the instrument cluster.

I would be checking them with a multimeter, firstly to see if they are getting 12v, and 2nd, makes sure they are drawing current Thumbs Up My D3 Build Thread
