I have read the procedure for repair of the final stage (sword) here: http://www.bmwe34.net/e34main/mainte...ical/sword.htm

But was wondering if anyone had a more detailed version or a link to one that explains more in depth the repair procedures. I understand all the removal and replacement of the unit, I just need some pictures of what needs to be done on the circuit board and such.

I'm sure it would be easier to just spend the $100 for one on ebay, but would like to save the $ if I can.

Thanks.
