Volvo Owners Club Forum - View Single Post - Instantaneous MPG display and DPF Cleaning ?

I've had a couple of occasions while "steady state" driving where the instantaneous MPG nose dives. I was wondering if this was linked to cleaning the DPF and if others are also experiencing this.

For example - Motoway driving, 75mph, I-MPG ~ high 40s. then suddenly for a ~20 min period the displayed MPG drops to low 30's with no change in driving conditions. It recovers after some time. I have seen this a couple of times now - it may be happening quite often - I just happened to check the instantaneous MPG display.

Similarly today, driving around town, the displayed MPG was <10 - and there was a definite "burning" smell outside the car when I stopped.
