In recent months, the glow plug indicator has remained illuminated post-startup, necessitating the replacement of a glow plug each time, as indicated by my previous Foxwell scanner. In total, I replaced three glow plugs over a span of six weeks, which resolved the issues. I utilised some old glow plugs when necessary, intending to acquire new ones subsequently.
Ultimately, I procured new glow plugs, and during installation of the Beru components, cylinder 5 exhibited an open circuit, which was concerning. I changed it, and all functioned properly. Subsequently, cylinder 1 also went open circuit; I replaced it as well, and everything is now functioning correctly.
Is there an underlying issue causing my glow plugs to fail, or are the new glow plugs defective? Additionally, I experienced this problem prior to installing the new glow plugs.
It is noteworthy that each instance the scanner has indicated a glow plug, it has consistently been the case that the glow plug has failed due to an open circuit.
I am aware that glow plug relays might malfunction, although I am not receiving any failure codes for the relay. I would appreciate the insights of our OM642 experts. Thank you in advance.
