You would really think in todays world that a metal manufacturer would have better quality control than this, especially given the work involved in getting this particular part out and back in. Where I work, (much larger scale but metal manufacturing for industrial parts) all the flanges are laser verified on every piece as part of qc before they go to the paint & blast shop. It’s a shame. I’ve reached out to the company and sent them some pictures so we’ll see what happens. Still no resolution from ecs either. So I will continue to push forward despite the road bumps and slowish supplier responses to help rectify the issues. I really was hoping for a new system to increase reliability but if I can clean the old dpf and reinstall, it will be good enough. it likely has far more precious metals content than the aftermarket dpf anyway and a much greater serviceable lifespan. We’ll see on Monday when I get the old one cleaned, if they say it’s still serviceable, it’ll go back in (once it’s emptied of 215k miles of ash). I’ll at least be up and running again. To bad no one makes a modular dpf for these, where you can pull the “filter” element section and just have that cleaned every 50k miles.
