BMW seems to have changed from the E-Torx to the internal Torx head style mid way through production.

I rounded and eventually snapped the head off the E-Torx on one of them; no amount of heat/penetrating oil/impact with an extractor socket would budge it. I ended up removing the knuckle and drilling/backing it out with a left hand drill bit. Managed to save the threads thankfully. New ones went in with nickel antisieze.

On my 2001 the originals were external Torx E12. I replaced the ball joints with Lefoerders which came with Torx T45.

From my notes, the trick I needed was to remove those E12 screws first, and then the standard ball joint separator that I use on all my cars worked fine.
