After hours of thread reading, still confused
On cold start and up to temp, car is a wee bit lumpy, but puts out blue smoke and smells slightly, this only happens until up to temp.
No fault codes. Injectors changed (on recall) 20k ago. EGR valve cleaned <10k ago. Oil & filter <5k ago and again yesterday with balancer shaft/hex drive upgrade. Full service (incl fuel filter) & cambelt change <20k ago. New turbo at 45k ish.
