Hi guys
In need of some advice please my td6 suddenly developed a noise from the turbo like a high speed dentists drill. The car has done nearly 200k miles so fitted a reconditioned Garret turbo and still have the high pitched drill type noise.
Car is very sluggish when accelerating from a standing start as well. Apart from that it appears to run fine No lights on The dash. Any help greatly appreciated.

Did you ever find the problem? Thanks
