Hello,
I’m back, exact same fault returned, I changed the glow plugs, including the cylinder 3 glow plug with integrated pressure sensor, and this has not been resolved… YET.
BUT… I finally have clearance, after scanning and doing multiple tests, and researching the fault and the similar symptoms from other people having the same issues on YouTube etc, (glow plug light flashing) does not always mean the glow plugs are faulty, however I am happy that I have replaced them all anyway, because it is a serviceable part and I will not have to worry about it for a while, hopefully.
Anyway, the G31 fault as seen in my original thread post, points to the manifold boost pressure sensor located in G31 on the workshop manual, and I have ordered another G31 Manifold boost pressure sensor and this has to be the issue, my theory is that because the underlying issue of this sensor throwing intermittent signals and sometimes even high signals, it is confusing the glow plug pressure sensor as some of the readings and pulses given from this boost sensor to the glow plug pressure sensor in cylinder three are not corresponding, therefore the sensor is more than likely faulty. No air leaks or boost leaks anywhere after tests.
I will update this forum once I have 100% diagnosed this issue.
Cheers
