Intermittent Black smoke - not the main intercooler hose
This ones vexing me, normally after driving a while I get the symptoms of a split intercooler hose i.e. sluggish initial acceleration, cloud of black smoke out the back but as said it's intermittent. Yesterday I changed the main intercooler pipe for a new silicone one and I thought it had fixed the issue as drove it 10 miles this morning, no smoke, indeed it went for an MOT and passed with flying colours, a short journey of 4 Miles to the office and all clean. This afternoon after 6 or so miles it was OK then sluggish initial acceleration and black smoke
it'a had as said a new main pipe and 2 Years back an intercooler, BAS EGR blanking kit and Map sensor cleaned. I also did the turbo lever arm thing a couple of Years back but haven't checked that recently
No relavent fault codes present other than low circuit on EGR's which it's always had
Any pointers/ ideas gratefully receivedMark

Black smoke is over fuelling, white smoke burning engine oil. Possible MAF might have packed up?

Have you checked the jubilee clips are tight / come loose ?

Definitely tight
If it was the MAF would I not get a fault code?Mark

Try replacing air filter as it could be collapsing starving it of air , or check the other inter cooler hose

Mine was doing this when I bought it. Previous owner had changed hoses. The fault was a crack in the intercoooler. Worth a look.

Tanglewood, you're right the Intercooler is split which is all the more frustrating as it was replaced just under 2 Years ago
I wonder do genuine parts have a 2 yr warranty?Mark

Parts warranty is 12 months but worth asking the dealer that fitted it. It should last longer than 2 years. They may have fitted it incorrectly and stressed a joint? Worth a poke. At least you know what the problem is.
