    Replaced (No2), fault code P0672, cleared DTCs with VCDS, everything fine, it was lashing rain so I didn't spend much time looking at the others but a quick look at the time seemed to say that all 4 are the same, but I thought No3 also monitors the cylinder pressure as well so would be pretty obvious, I will have a another look when next I see the car.

    Yes, no3 glowplug is the one that measures the cylinder pressure as well.

    Just a word of caution to anyone who may be advised to change all 4 glowplugs + the Nox sensor No2 fault that was flagged as well, my daughter got this advice from a fairly well known (independent) garage in West Cork, a OEM NOx sensor is probably around €600/€700 so not much/any change out of €1000 to do the lot, seemed very strange advice to say the least, but the good news was they only charged €35 for the scan.
