You have a reservoir, not a pouch system, so just need to top it up (minimum 1 litre) and reset the additive counter in the engine ECU with a diagnostic tool (essential). You need Powerflex additive.

Incidentally, you have an outstanding after-sales campaign for the check of an electrical harness in the engine compartment and replacement if necessary. It has been outstanding since 2020. As you obviously don't have your vehicle dealer-serviced, you would not be aware of this, so I suggest you call your Citroen dealer and quote Reference HKT, the work will be free of charge.

As for the fault code - you may also need an engine management software update as well as filling of the additive reservoir.
