My 2019 brought up the message "Perform DPF Regen" as if I could choose this function manually. Checking the dash, it started at about 84% and came on every time I started the van. I drove the van for about an hour and the DFF reading went to about 98%. I suppose this will start at 100%. Does all this sound normal? Did everyone else get the request to perform a DPF regen?
