Really in need of some help or advice here please
My DPF light came on today, so went on a run on the motorway to try clear it. It didn't come off by the time I stopped, however as I was coming off the motorway when I changed into 3rd I seemed to loose a lot of power, a huge puff of white/grey smoke come from the exhaust and then power returned
I stopped turned the engine off and went in a shop for maybe 10 mins. When I came back out the car wouldn't start, it was just cranking very very slowly
After letting it sit for an other 5 mins, the car started but then ..... after about 100m the car accelerated full throttle on its own, and I was engulfed in smoke from the exhaust pipe
I quickly turned the engine off and give everything a chance to 'settle'. The car then started up fine and I had a very bum twitched 4 mile drive home
The car will start fine now but I've not been back out in it. Does anyone have any idea at all what could have caused this or if there could be something serious wrong?
Thank you!!
