Adaptation 1.9 TDi BKC with arl injectors and turbo

it is a genuine garret but has 100% been rebuilt recently(says garret on housing but maybe Chinese parts used for rebuild ), it was from a 2005 leon FR from the junk yard, strange thing was the car they said was driven in, but seeing the car it seems strange why it was scrapped as it was a nice car, maybe it was the turbo issue.
