I have a galaxy 1.9 tdi 115 bhp and we had the same kind of whirring noie when we accelerated, this had been going on for a while and also if my husband drove he seemed to lose power if he went to 60 or over. Anyway today we started the car and loads of white smoke came out and also carried on white smoking alot when driving and there is a different noise now and has lost a lot of oil but there is no leaks (he only filled it up last week). Could the turbo have gone or could it be something else? Thanks
