Eventually, the pump would fail, resulting in the errors you saw on the dashboard. PSA fixed the issue by using an AdBlue cap fitted with a small pressure release valve. If caught in time, a new cap would fix the issue. If not, a new tank was required. Unfortunately for you, your C4 missed the recall and is now outside of the warranty period.
