DEF - Diesel Exhaust Fluid Video
Since the question about DEF comes up here I thought this video can clarify some misconceptions and how DEF works in the Exhaust System. Enjoy... Link

One of the things I don't like about my truck, is the limited information it gives you about the regen cycles. On a normal regen, if you miss the initial "Cleaning Exhaust Filter" message that only displays for a few seconds, and you don't pick up on the slight change in engine noise, you don't even know a regen is happening or how long it lasts (unless you manually run a system check, and then the last thing it tells you is "Cleaning Exhaust Filter" if it's in regen). The only time it gives constant indication of a regen is when it displays "Drive to Clean Exhaust Filter", and then it will display the message until the regen is finished. It would be nice if there was an icon that illuminated every time it was in regen. Do the 6.7 truck give any more info?
One of the reasons given for changing the regen message was dealers were fielding too may inquires as to why this message was occurring. The early tunes did show the message and it stayed on until complete.
