Hey all. I have a 2020 6.7. Three weeks ago it threw a check engine. Then after a couple of days it said exhaust filter nearly full. Drove the snot out of it to no avail. Never went into limp mode. Shop said it had a turbo problem (covered by warranty) they also told me if unit throws the check light the pcm will not let it go into regen. Fast forward to today. Check engine light back on. Anybody else have this issue and are they right about no regen when check engine light on?
