2014 Ram Promaster 2500 159" diesel
Regen light came on while at the dealers never saw one in 15000 miles. This was after service for check engine light related to turbo control. As to whether the bcm update or his work or as they said it being normal I got no clue. The diesel Mechanic said when the lite comes on I should drive until the lite goes out I say how many miles, he say's I think 7???? let me look. He was trying to say 70. I say my 7 miles from town to home not enough he says no. So he gets on the puter and starts looking and like the rest of us all he can find is what the light is for, but he says he'll look into it and have a rep call back. And my official regen light did go out at 19.5 miles driving at 70mph from the dealer this was with a stop for cheap fuel at 4.5 miles from the dealer. My dpf temp reached over 1000f this was the highest temp I have seen from my scan tool. My scan tool in the past the regen temp's were only in the 800-900 range. My two previous regen's were incomplete so could this just be a super clean burn. I'll see if the regen light comes on at the same time as my scan tool at next regen by scan tool.
