According to the Pentosin website the MTF-2 is for: "BMW with ZF & Getrag manual transmissions (1997 on)".
It's a GL-4 spec fluid. Here's the info:

Edit:
Hmm, actually the top one of the two BMW reference numbers does actually refer to LT-2 fluid. FFS!! I asked about this for ages and deliberated for weeks on BITOG and here, and nobody said it was the wrong fluid, then as soon as I put the stuff in somebody says it's not right! ARRRRRRGH!
What is the difference between the LT-2 and LT-3 then? Pentosin don't seem to make anything other than MTF-2...
