had new turbo fitted to work car few weeks back, done 5k kms since. started making bad turbo noises and then the motor started making bad noises.
took it to mechanic and told him the turbo or something and he said timing chain (there was a rattle), fixed that.
Now they obviously took it for a drive and the turbos stuffed. better cover it under warranty cause id taken it back twice saying the new turbo had an issue and the bloody thing ran fine while the mechanic had it.
