I have a 2013 Volvo d13 and I got a check engine code: spn 5394 fmi 17 I just replaced my egr cooler and my def fluid seems to be used less. My question is how serious is this code? Can I make a trip? It had me do a manual regen. Then I drove it for like 10 miles, parked, shut off engine. When I drove it after the regen the check engine light disappeared. But after I shut it off for 5-10 minutes and started it back up again, the check engine light came back on with the same code... How serious is this? Safe to go on a trip?
