Hey Folks.

I was wonder if the glowplug errors are actually legit. or cylinder 1-4 errors could be caused due to glow unit error

sometimes I get quite a rough idling when hot or cold, does not matter.

I first thought It was battery related, (the battery was bad) and had it replaced.

all error were cleared and these are the ones that came back after a few days again.

any input?
