Egr tune up

[Waterloo]

There is one down at the DPF, maybe two, been awhile... When I eliminated the mandate, I found the tubes going into the DPF were stopped up with soot, the sensor(s) the same. Nothing was functioning under there. And if you mess with the metal tubes coming off of the DPF can, be prepared to have them snap off on you, mine did, looked like cheap pot metal and broke under very little force. I could see a well placed road stone taking one out if it hit the sweet spot. Nothing but junk under there, and designed to fail in my book.
