When mine died a few years ago now, I started to remove the regulator and came across 3 cross head screws.
Two came out with difficulty, one just got chopped out badly so in the end I couldn't get mine off. Whacked it back in drove around for a week just charging the batteries as needed, new alt came .. and went in.
I still have that old original to fix up one day.
ps. 15mm bolt heads are common on the 300 Tdi.

All these discos are giving me a heart attack!
