It's all a result of new emissions laws in effect for diesels. In place of a catalytic converter, the new Ford 6.4L diesel engine has a DPF or "Diesel Particulate Filter". It does a very good job of "cleaning" the exhaust. So much so, that there is virtually no odor, and no black soot inside the tail pipes. As a matter of fact, the new trucks don't even have a muffler - the DPF also quiets the exhaust. One drawback is it must be cleaned out every fourth oil change (you can open it), and must be replaced at 60,000 miles at a cost of $2500. The other drawback is the exhaust runs hot. Very hot. At times the engine computer goes into a "Regen" mode, which effectively cleans out the system and makes it run very hot. Even before the recall, there were reports of grass burning, or drywalls in garages burning.
The recall is simply a re-flash for the computer. Takes 10 minutes. The part I don't like is the computer is supposed to reduce power now when it senses excessively high exhaust temps. I'm not to sure if I like the idea of losing power when I'm towing something up a mountain.
They have to get this ironed out. There are other problems with the engine as well. It hasn't been uncommon for there to be computer reflashes for Powerstrokes. Take a 2002 model year truck - there might be a dozen flashes out already for it.
