Hi, i got the check engine light on and after a check with a real scanner and not the one ford provides in the car i got the error code 0400 which after some digging turns out to be a problem with the EGR valve or solonoid,
could i get some info please on what is the easiest and cheapest way to fix this problem?

i live in norway and the repair costs here in a workshop are insane so ill be trying to do this myself is it possible?

thank you for the help!
