Hi all, think a turbo has went on my 2017 4.4Sdv8. Been coming up with boost faults, solenoid faults. But today it put out a hefty amount of smoke and what would sound like a diesel knock. Randomly it still pulls well but take you foot off and it smokes. I don’t see a lot about the turbos going on these. Is there anything else that gives these symptoms or is it remortgage the house time? A bit annoyed as it’s only done 70k with FRRSH
