I sent my twice to Turner Diagnostics in England and they had to reprogram it because it seems the GM dealer blew the flash memory. So they programmed it with a new transponder chip. I thought finally after 8 months all I need is to have it married to the ecu. Wrong the 3 GM dealers here deny that GM ever sold and serviced Saabs and that took weeks to get because you have to leave a voice mail and they never respond. But there is one last hope a guy here has all kinds of awards for diagnostics and he is going to see if his Tech 2 will marry the system. Turner in England says it is a simple proceedure but up here in the great winter north it's very hard. BTW one guy says he bought a new piece of equipment and it might work but the only thing he can guarantee is the $400 it will cost.
