Technically there is all sorts of differences. the TD5 is a 2.5 litre bmw sourced, 5 cylinder turbodiesel engine.
the TDI is only a 4 cylinder and although advanced for the time, is relatively simple compated to the TD5.
I'm afraid I can't tell you much more than that other than the TD5 is more powerfull, smoother, quieter etc etc.
