Inter cooler O-rings or a split pipe leading to the turbo more than likely.

Glad you made it home though Ian. Best of luck in sorting it.

Hi Andrew
O rings have been changed so should be OK but will have a check for split pipes..

Power loss and black smoke means a boost leak, normally.

Hi Ian. Although unlikely, I had the same problem and symptoms on mine last year. I stripped and rebuilt a lot of bits and pieces, had the synergy checked, replaced the \maf and lots more. Code reader kept saying inlet manifold pressure low. A week later I removed the ERG bypass to find the "washer" between the exhaust and the EGR had blow a small hole through. Relplaced the metal disc and no more problems.

right angle pipe popped off the turbo on mine and that did cause ploooms black smoke and as you say loss of power.

Cheers Ian
