Hi. I have a mileage restriction on board and the check engine, service and adblue warning lights are on with the antipollution error message. The error code is B1811 fault on the diesel fuel pump present. The question is the following: which additive pump is faulty, the adblue pump or the eolys pump. Citroen c4 picasso, 1.6 bluehdi 2018 ? Thank you for the answers

That code relates to a fault with the DPF Eolys Additive Pump, not the SCR Urea (Adblue) Pump.
