DEF and P20EE
I changed my DPF for a new one because I was having a lot of issues. all problems was fixed! But now the DEF is low. so I added half gallon and it barely moved. I read I need 8 gallons to fill it up.
well I used a DEF that isn't the OEM called Blue DEF.
but after that a few minutes later the check engine light came on. error P20EE. so I guess the DEF doesnt works like the OEM.
if anyone can help me out I appreciated.
what DEF brand is good quality for my JEEP?
