I have been experiencing my DS4 idling rough when I start it on a warm day.
it sounds like it is running on 3 cylinders.

After a while it runs fine.

I hocked up my car to a diagbox and it came up with lots of errors codes, after clearing them it bought up the error below.
Looking through the log, it looks like it had the same error at 6km (when the car was new)

Do I need to replace/clean the EGR or somewhere I read this rough idle is related to a software issue?
Someone else mentioned I need to change my glow plugs, so currently confused what to do? Any help greatly appreciated.

Who done the work and cleared the codes?
Actually I did the work myself, I bought a diagbox and a new egr valve and replaced it.
And to clear the codes I went to the repair menu and cleared the fault codes, there was another fault code along with this one but this one reappears.
