Glow plug light but no diagnostic code

Thanks for all the info and yes I've replaced the module and all 6 plugs.
Tested all plugs - ok
Tested wiring to plugs -ok
Tested voltage to both module plugs -ok
Did notice the wiring to passenger side front plug comes from a little round relay thingy not sure what that is!
The plugs dont seem to be working as its still struggles to start on occasion.
Star fault code just says Lin Bus fault.

Have you found a solution yet? i have an issue that car starts well (unless its really cold) the GB light is always on, it might turn of for a minute time to time.
car has been read on Star and it says Lin error..something, cant recall... i have had this issue for an year now. last owner said that he has changed the Module and it didnt help. now that winter is coming im back on trying to find the issue.
