DPF Regen - Whats normal?!
Would like to know whats normal during DPF regen. The normal which I have is MPG drops through the floor, exhaust has a bassy note, can smell a burning type smell if get out / open window at slow speeds. The one which I think is not normal is the car shakes / shudders at steady or light throttle between 1.5k and 2.5k rpm in pretty much any gear at any speed. I can feel this through the steering wheel, pedals and seat, its quite bad. Can overcome it by planting the right foot or dropping a gear or two. Once the regen is over (about 5 - 10 mins), the mpg improves and driving is back to normal.
I dont think there are any related symptoms under normal driving but ive only drove this one so nothing to compare to!!
Is this shaking during regen normal and if not does anybody know what causes it?
