I was ready to remove by door today when I discovered that the forward upper bolt has a special, non-hex head. Looks like a Torx but by Torx tool would not fit tight enough to break it loose. What kind of tool do I need to remove these bolts?
 
Procedure

Re: "The door hinge should have four phillips head bolts into the A pillar."

I am following the procedure in the workshop manual. My goal is to re-skin the doors. What are the good points / bad points of removing at the door vs. at the A-pillar?
 
As to removing the hinges, I wouldn't. Unless and only if you have to refresh the hinge pins, etc.

The theory is that you'll be refitting the doors many times while shifting the skin a bit to match the body and contour lines. By leaving the hinges you only have to worry about getting the door re-aligned. But that depends on how much restoration of the door frame itself you must do. It's easier to grind the edge free and then deal with what's left.

You said skins, which means the whole skin or did you mean just the bottoms? There's a different procedure for just the bottoms. There's another for just the top where the trim clips scratch and rust.

I used an allen wrench/socket in the head of the bolt you have pictured.
 
Looks easier from the door itself but I have never done either. Isn't there a Star bit, similar to Torx but more points?
 
That fastener is a triple hex with 12 points. A regular Allen has 6 so it grips half.

Unique to German cars on high torque fasteners as far as I remember.
 
While an Allen will work in the 12 point heads , be careful. It doesn't get a full grip. These fasteners are actually 3 squares not 2 hex's...... You used to be able to get these bits from the tool specialists (Snap-On, Mac, etc....) They were called triple square, I think.... but I haven't seen them for a LONG time......
