Hi all, I have got a 2017 SDV8 with 70k miles on and was coming up with turbo shut valve faults and boost issues. It then started smoking. Spoke to a specialist that said it would be the turbos that have gone on it I have stripped into the turbos and it had loads of oil in the inlet pipes but the turbos feel fine no shaft play and spinning freely Has anyone else came across this and if so where was the oil coming from? TIA
