I have a tdi sport 130 saloon. The other day I was informed by the old man, that when he was following me, i was chucking out a bit of black smoke under acceleration. Also i have noticed that it is quite noisy under acceleration or downshifting (i.e. it bellows a bit). This is my first diesel i have owned so I'm not sure whether the noise is normal or not, but I'm pretty sure it shouldnt really be black smoking.
The car has done 89k miles, and is completely standard (as best to my knowledge). Would a egr blank and inlet manifold clean sort the smoking out? or am i looking for split boost/intake hoses causing the smoking and the noise?
