i have spoken to meny of people about this, i fine it very hard to belive that a turbo would blow up due to swaping cars (because it made very good sppol on mine) before swap.
chips as i have said to you you are more than welcome for a refund and fitment, this dosent solve the issue.as i cant see how it can be the turbo unit itself at fault, i would like to get the car back to the garage to check for exhaust blow before the turbo and valcume pipes etc before i would say it was the turbo.
all i can say is i am sorry for the inconvence, i would never sell anythink i am not happy on as i like to think as my customers as freinds as well.
