I have a 2008 Gulstream Crescendo and driving from Houston to Dallas the "Regen required" light and words came up on the dash. On the way back it changed from that to "Regen Soon" and then 30 miles later went to "Regen Now" with and alarm. The amber light continues to blink, though the red stop engine light has not come on. Doesn't the engine automatically regen above 45 mph? I was steady 65+ for 3+ hours. Am I doing something wrong? Is it a sensor I can reset? Please help. I only have 11000 miles on the vehilce.
Thx.
