I commute about 40 miles each way 5 days/week on a 2 lane highway. For the past 3 weeks, it has been under extensive repair resulting in long delays and extended idling. Today, I started my CTD and was greeted with a CEL and reduced engine power message. Code P2463. Great. Appointment in 2 days at dealer for this and NOx position 1 sensor recall. Can I reasonably hope that a manual regen will fix it or will I be on the hook for a $258 DPF plus $100 x 1 hour labor?
