I would hesitate taking any car with this engine and turbo problems to anything other than a very experienced mechanic- we have had a bulletin at work from BTN Turbo regarding replacing them. The instructions for changing are VERY specific- to the point of measuring the exact amount of oil and running it for the exact number of mins then changing the oil again etc etc. There is also a specific turbo filter which must be changed after turbo failure. If the instructions (which run to many pages!) are not followed to the letter the warranty is invalid. It would seem that BTN have had many cases where the new turbo has gone pop within a matter of hours of it being fitted and it not being done properly.

Its a cracking engine when under manuf. warranty but I wouldn't touch a secondhand car with it fitted.
