Morning all,

2007 E60 LCI with M47 engine

I get occasional lumpy starts on cold mornings for a feel seconds , this throws up glow plug fault codes for cyl 2&4.
I figured it was just 2 glow plugs on the way out and that I could live with it.

Only recently when looking at the diagnostics report in inpa, the faults for 2&4 occur at identical mileage/time each occurrence, couldn’t be a coincidence could it?

Am I right in saying that this is pointing towards the glow plug module being faulty rather than the plugs themselves?

Would be a much easier fix!

John.
