Hello My wife had a red tringle warning and asked me about it. I thought it just needed a diesel regeneration so she brought it home and it said no more restarts. I did the regen without turning it off on a autel scanner tool. I filled the DEF up just over a week ago and it says its empty. Will it start after being empty if I fill it up? The regeneration worked I'm sure but didnt solve the problem. Is anyone using a large amount of DEF???? If filling it up doesnt get her started does anyone have clue what I can do ? Help, Thanks all.
