Stubborn DPF sensor questions
I finally got around to taking out my DPF and loading my Spartan tune today, but I'm having a heck of a time getting the sensor furthest to the rear out. I've soaked it with penetrating lubricant, I've used a breaker bar, everything. All I've managed to do is break a wrench and scar up the nut.
Tomorrow -- after the lube dries away -- I'm going to try to take a torch to the exhaust bung and see if that will help, but this thing is tough.
A couple of questions for the experts on the board...
1. What's that sensor do and how bad will it be for me to drive without it in?
2. If I can't get it off, does anyone know how much those things run at the dealership?
