Help, think my turbo just gone, 1.9tdi,X reg, has been noisy for years, with a wa wa wa sound on the throttle off, but the last week it has had a metalic sound coupled with the car being very slow and juddery when cold, I wasnt to worried as ive had it before 3 times and its cleared itself with some turbo cleaner, not this time, the noise turned into a loud whistle, thought the cops were after me,,, then loud grinding noise, then limp mode... still drives, no turbo, and no smoke???? Any ideas, and jf it it turbo, how much am I looking at? The car is well maintained , black elegance .... thanks any help would be great

Il be honest I no nothing about the 1.9 diesel but I would check your egr system if it has one for cleanliness as a dirty egr can cause these sorts of issues, if you can get the air feed to your turbo off have a feel of the turbine shaft, you should have no more than a tiny bit of movement up and down as well as in and out, your seals aint blown cos ud have non stop smoke if they had. 

I had another make of car before my first Octy and it had the police siren sound after being just a bit noisy for quite a while. 

I fitted a secondhand turbo (same part number) obtained from a dismantlers with a short warranty. Problem solved.

It was the turbo bearing(s) that had failed.

Thanks guys, defo the turbo gone, just weighing up wheather its worth doing, turbo labour , egr clean out and my cambelt is due..... but the car is imaculate.

Can you buy a "new" car that will give you another 4 or 5 years reliable service for the price of a new turbo and cambelt change?
