P200D Particulate Filter Over Temperature (Bank 2)
A temperature sensor at the diesel particulate filter (DPF) on bank 2 has exceeded the safe limit — typically during a runaway regeneration. Continued operation can melt or crack the substrate.
Is it safe to drive with P200D?
Usually safe for short trips, but don’t ignore it: the underlying fault can get more expensive over time.
