hey can anyone help, as i need to reprogram a BMW GM5 module for my car, is it possible to do this at home or does a dear need to do this, and if a dealer need to program the unit roughly how much does this cost?
 
"You sometimes can find GM5 modules on ebay or by specialist breakers but you will have to have the unit programmed .

Scott, of the BMWGM5 website, can do a service for a very reasonable price. Or you can order the parts (relays) from him and do it yourself. There is plenty info available of how to do it.

I have just noticed this thread, I got 2 new relays last year & fitted them myself, carefully, but using an old soldering iron & great care while sat in the Kitchen late at night when i wasn't going to be disturbed! I used some solder extractor, which you put on the soldered joint & this draws the old solder out when you heat it up. Some of the finer connections where difficult to draw out, but i found it was easy if you first added some solder which then gives you a bigger blob to work with when trying to withdraw the solder. The removing of the solder is the hardest bit, re-fitting the new relay is the easy bit.

I would say be brave & give it a go, too many people give up too soon or they have too much money!!! " - Quoted from another source.

Hopefully that helps (I couldn't be bothered to read the whole thing).
