So driving to work this morning my freshly serviced and mot'd vw polo (diesel) started juddering, kind of like it was mis firing. When I got to work I sat and let it idle and it was stuttering with an occasional little bit of black smoke from the exhaust on the occasional big judder.
Not very knowledgable on engines (in particular diesels) so wondering if anyone on here has a clue to pre arm me for when I speak to a garage.
If it makes any difference its just clicked past 170k (51 reg)
Cheers,
