[Half a stereo]

Hello all, well I finally got planet running. I had the dpf fluid and tpms systems to reset and that all went ok and seems to have worked but in the ECU scan I had 3 permanent faults

can anyone help explain these, I assume the first one is a relay or glow plug issue, hopefully I can use a multimeter to test the glow plugs as it seems a pig of a job.
Hopefully the second fault will rectify itself if I sort out the first fault seeing as I have filled and reset the eolys tank?
The third one..... hmm something to do with the thermostat I've heard?

Cheers everyone?
