The GTI and TDI of MKV years 06-09 would fit. If you're talking about the trunk/hatch, I believe 2 and 4 door are the same. I would check with the salvage yards or LKQ.
The bare hatch from any MK5 will bolt up, what will vary is what electronic are installed in a complete used hatch and if it will be a direct swap or if you will need to move some of your parts over to the replacement hatch.
