2012 MX-13 EGR CLEANING

[Waterloo]

The sensors need to be replaced yearly, at least that is how often I would replace them. You are wasting your time cleaning or brushing them off. And only use OEM sensors, stay away from the cheap Chinesium crap, as you will pay for it in the end.

Clean the soot out at the same time and keep the cans fresh and operational, remove and bake at 250,000 miles, replace after that with new ones. And do not forget your fuel doser.

The SCR system is where everyone screws up, that system too has to be serviced. I would say yearly on any sensors, and there is filtration on some systems, that should also be completed yearly, along with inspecting the lines and what not for leaks and cracks. And do not forget the Urea loser, there is one under your cab somewhere, they need to be replaced every two years or so, if not sooner depending upon mileage. That urea is nasty and can cause a lot of damage if not maintained. The NOX sensors too...

Do as much of the work you can, as the dealer and these shops will rape you. Maintaining these emission systems is not cheap, figure at least $3000 to $10,000 a year. Or more if the system is neglected, $20,000+ is not out of the ordinary if a dealer does the work. And odds are, they will not fix the issues.
