Hi chaps
Thanks for the info.
After double checking with my mate, we reckon that Mr. Yut was torquing our nuts to 42Nm! His information was from a book, which was obviously out of date. No wonder the threads stripped and 'he has seen the problem quite a few times'.
Anyway, we let him sort the problem out and he had new studs made with a larger thread and fitted them. Not sure how he drilled the hole, but so far all now seems AOK for a total cost of about $100. Not the end of the world by any means.
I also found info from the BMW owner's club of america which categorically states 35Nm maximum and ALWAYS slacken the nuts before torquing them or the studs WILL pull out.
Thanks again from Phnom Penh.
