Hi all, I have vw golf mk4 gt tdi, owned for approx 1 week, drove back 160miles noticed temperature gauge not working so changed that problem solved. Then noticed a lot of white smoke from exhaust, literally fills the rear view, not the head gasket, turbo has slight play in shaft but only approx 1-2mm tops. Smoke has oily smell, Have no idea what could be, smokes more when engine is warm, turbo pulls fine no rough idling. Don't think it's the injectors, Any ideas??
