Hello,
I have a 2012 Roomster (5J, CFWA 1.2 lit diesel engine) and I am about to change the fuel filter. But, I do not want to ruin my engine, so does anyone know "the code" or "how-to" to prime the fuel filter/system with both the auxiliar and lift pump to fill the new filter using the OBDEleven?
I hope you all are well in these times.

Hello. I have the same engine in a 2012 Fabia. To run the fuel pump with the engine off I do the following. Go into the Engine Control Unit Go to Basic Settings Scroll down until you get to Test of auxiliary fuel pump Press the green tick and the pump will run several times. It runs at about 4.5 bar so pushes a lot of fuel through. If you stand at the front of the engine you can clearly hear the fuel being pushed through the filter. You have to stop the process by pressing the button again. Hope this helps
