I decided it would be better to create my own thread:

I am having an issue with glow plugs, I managed to find a helpful post

https://www.fiatforum.com/stilo-guides/151734-dealing-preheat-fault-message-stilo-jtd.html

Although this is for the stilo it looks like its the same engine, the wiring is slightly different as the colours dont match the list, on the connector block from the glow plugs to the glow plug relay the pins are numbered.

Pin 1 - 1.5 ohm
Pin 2 - 1.2 ohm
Pin 3 - 180k ohm
Pin 4 - 1k ohm

Are pins 3 and 4 glow plus 1 & 2 or 3 & 4, if 3 & 4 I may have a go, 1 & 2 its in the garage.

Thanks in advance
 
I would just pull the plugs off the glow plugs and measure the resistance between the plug and the block.

It may be me but they look really hard to get to, the pictures I've seen are people with the socket set between the block and the egr valve, I'll have another look but it may be garage job
