I got home from work last night and my wife gave me a letter - told me we got a letter about a problem with my "mistress." :-laf
I was expecting a recall letter on the tie-rod thing, as I had seen that here on the TDR and in the news. However, the recall notice said that I needed to have the power control module updated because a possible miscalibration would allow excess NOx prior to end of expected useful life.

I am new to the diesel truck thing, and while I have been an avid student of the service manual as well as the TDR I realize I have a long way to go. At any rate, my experience with the truck so far has been excellent - I understand the 2013 and 2014 with the revised DEF/SCR emissions system are returning better mileage, but as far as my experience goes with my truck it has exceeded all of my expectations. So, I am not excited about messing with it - it sure ain't broke, so why do I need to fool around with fixing it?
Am I being a sissy worry wart about nothing? Have others encountered problems when having the PCM software updated?
As always, the help is appreciated.
