Hello fellow Ram owners. 1 st post in years. Never had a problem with my past Ram 2500's. I have a 2019 2500 6.7 . I have the New/cp3 pump installed. Drove fine for 750 miles then engine light and the code 2459 regen frequency came on. This happened shortly after starting to tow my trailer 8K. Took it to dealer and they're trying to tell me its due to a wear/scoff mark on thr airAir Charger tube coming from the turbo to the air cooler, They say it leaks and causes this. They also say it's not covered under warrantee. wanted $1200 to replace it. I found OME part for $212.00 . My inspection shows wear mark from wire harness but no hole/leak. Has anybody had trouble with the Air Charger Tube leaking causing a code ? I've loss all respect for what I thought was a straight up dealer. Thoughts ?
