I did post on the door handle fix, how to section but no biters so in true Barbie style I want my own post

Muffed up on door carrier fix and caused the airbag light to illuminate leaving bmw trying to rob me of £65+ vat to turn a light bulb off.
I've looked at loads of tools on eBay and searched the forum but unsure whats best. I'm sure I saw that the 1.4.0 is the best tool for airbag reset but not sure.
I asked Jochen (programmer) who wrote nav coder if it would do it with my resler but he told me that won't do it unless I know the codes.
Can anyone provide me with a link or advice so I can ensure I get the right tool

Pretty please
