I had a serious situation with this car today; attempting to burn off the soot in the DPF by taking the rpm to over 3500 in second gear, I had the engine suddenly taking over the rev’ing and hitting the redline in a flash! A great big puff of white smoke was left in the wake of the vehicle and the engine acted very strangely.
The car came to a halt. I managed to start it up again but it sounded quite ominous with a clacking sound seemingly coming from the timing gear. So, I was able to drive on to my destination down the road and turned it off. The engine now had a quite harsh ticking sound, and a moderate amount of white smoke emitted from the tailpipes.
After half an hour I started it again and drove for ten minutes back home. The ticking was less obvious now, and no white smoke but there was still a slight ticking sound.
Any wisdom on this kind of thing here?
