I have the same problem. How long does it blink? (seems to blink 15 seconds if problem with one glow plug, 30 seconds if problem with two glow plugs etc.)

Check:

- Glow Plug relay (also check fuses)
- Measure Ohm Resistance after disconnecting 6-pin cable from Glow Plug Relay (only 4 wires connected, one to each glow plug), by using a multimeter. Resistance between "ground" and each of the 4 wires should be apx. 1.2 Ohms. A higher Ohm value could indicate a faulty glow plug. If no resistance measured, this could be due to a faulty wire.
