P1590 – Engine Running Signal High Input not present.

car runs like a bag of poo but once warmed up its seems ok.

What the relative resistance of all  your glow plugs. I forget now what the codes were, but both on the Astra G TD of mine & that of my s-in-law's Astra H a code referring to glow plugs lead to me a failed glow plug.

Check to see if the resistance of all the glow plugs is more or less the same .... the one that isn't is the duff one! 

no idea on the other codes

Ah good ill have em out and stick power to them and see who glows thanks.

No, just stick a multimeter on resistance from the contact on top of them to earth (or for Mark zero volts - the block)  As said, you're looking for an odd man out reading of the four

Be aware that sometimes these plugs tend to seize in the head

I'd also fully clean out the inlet system, to allow all the inlet sensors to work

Is there a correct procedure for this?

Ill get my meter out 

Any other hints on the other codes. I tried clicking on the malfunction 2
 but I got no further details and the high signal missing?

[Y26SE]

confirmed GP no4 open circuit. cheers for that one people. ill get one from the factors tomorrow

An additional fault has just popped up aswell now. on the mid screen. low beam vsr fluid or something like that

HID level sensor is upset. Sometimes it's as simple as the front sensor's arm has popped off

ill have a look tomorrow at that aswell

is the P1590 code a battery or alternator voltage issue? and the critical malfunction 2 is related to this

[andymp]

P0400 means maf sensor reading out of operable limits. Usually caused by an egr malfunction. Check vacuum rubbers.

[andymp]

P1590... check your alternator output voltage.

Just a quick question on this arm. Is it easy to see the arm on the headlight or am I looking at the fabled plastic adjusters that go
