Ok, so there are NO recalls for your vehicle and as such I can't tell you what the above codes are for - as they are not relevant to your specific vehicle.
There are only 2 recalls so far for this model but not yours and again none apply to you. One was for the this vehicle that was the Chinese version and the other on the 2021 model (JGT) that concerned the front left wheel mounting bolts may not be properly tightened, which can cause a loss of vehicle control while driving, creating a risk of an accident.
The Citroen C5 X vehicles affected by this recall were manufactured between 25 August and 6 December 2021.
I should of said, that once a campaign (not a recall) has been completed as in the case of the codes you've listed, they are no longer shown on the system - only the outstanding ones are. So I can't provide details now as they've been completed.
Most of those will be software updates AMVAR is the suspension - so probably a tweak there., PHEV will either be a check to add insulation to prevent corrosion in the gap between the battery and the casing where needed, or the battery management software needs updating to fix issues with either range or electric mode I suspect.
The steering wheel software may be for the controls / functions.
