Hope someone can point me in the right direction 2006 2.0 dci 115 Vivaro. Was running rough and jerking about. I swapped out the fuel filter as I don't know when that was changed as only had the van a year. I also swapped out the boost solenoid as it was making odd noises and rattled. At the same time I checked the vacuum hose from the solenoid to the turbo to make sure that was not leaking, kept a vacuum nicely. Now it's improved enormously with good acceleration and runs pretty well and tick over spot on. I am still having an intermittent stutter, it then puffs out some black smoke and then carries on like no issue. No lights on the dash and no codes either. Any advise gratefully received.
