Hi all, I was driving down a duel carriage way yesterday, when I realised that the engine seemed a little louder than usual, and MPG was below normal. I assume that some sort of active regeneration was occurring. Unfortunately I had to stop and switch off the car and drop my son off. Whilst the car was switched off, I could hear some sort of activity from under the bonnet. Assuming that regeneration cycle was still happening, I jumped into the car and headed for nearest motorway where I could trash the engine for 30 mins. However soon after restarting the car, MPG seemed normal. In any case I still went on a long drive. I checked the oil today, and the level hasn't changed. So questions : Was active regeneration taking place, even though there was no light on the dash? Had I done the right thing in restarting the car and heading for a motor way? Are there any bad consequences to what I have done? What should I do in future if I find a regeneration cycle to be in action, and I can't let it complete because I have to end my journey? I would appreciate thoughts from people how have experiences of DPF regeneration. Thanks.
