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.
