#1: Jerking and Black Smoke 1.6hdi Author: 2jof, Location: BarrowfordPosted: Fri Aug 26, 2011 10:43 am ---- Every now and then my car, at low revs around 1500-2000, jerks when I gently accelerate and when it does this a puff of black smoke comes out of the exhaust. Could anybody shed some light on what this may be? feels like the turbo or something is going wrong, blocked pipe maybe?
Help would be appreciated,
Thanks

#5: Re: Jerking and Black Smoke 1.6hdi Author: 2jof, Location: BarrowfordPosted: Sun Aug 28, 2011 9:08 am ---- Fap has been removed so not that. this is why I am more inclined to go with the boost leak.

It won't, revs must be kept as low and steady as possible to allow regeneration, 50-60 MPH ideally. Whoring it up and down the motorway will only block up the filter more.
