C5 X7 Diagbox Eolys reset

Post by Viitonen »

Hi guys, I’m feeling stupid right now.
Managed to fill up the Eolys tank in my 2010 Citroen C5 2.0hdi.

I just can’t find the place from where to reset the service light plus tell to BSI that the tank is full again. Could someone map it to me, please 😬

It does vary from car to car, but normally you go into the engine ECU then repair then refill of the particulate filter additive. You may also need to go into the DPF ECU and do the same, and then back to the engine ECU and clear the codes!
