Well if you have an 08 that's actually a TD04.
If you have the 09, then you have the VF52.
Here's how it breaks down
1) VF52 is essentially the same as the VF48, but with a different flange that bolts directly to the intercooler. The VF48 just has an open end that uses a hose clamp and tubes to connect to the intercooler.
2) VF48 is essentially the VF39 but with a revised, larger wastegate to help control boost creep.
3) The above two points mean your turbo is essentially a VF39 with a larger wastegate and a different flange to connect to the intercooler.
