I have an original Bosch 5.7 module installed in my BMW X5 4.6iS. This module was once repaired in Moscow, Russia (not Moscow, Idaho!!!), when the car was there and the -40 degrees temperatures got the best of the module. Recently I was towing a U-Haul 5x8 covered trailer (using the original BMW towing package installed on the vehicle from the BMW NA, 40 miles total towing distance), and the DSC, BRAKE and the ABS lights came on. As it happened during the tow, I got a brief message that the DSC INACTIVE, did not get that verbaige since then. Since there is no speed signal, all speed related functions are dead. As I drove the car since the towing, I would get the issue intermittently, once there will be no problem, the next moment the problem is there, I do get the trifeca of the lights, randomly get transmission into LIMP mode, and eventually set some codes in the Service Engine Soon.
So, I suspect the module is acting up again (when the temperature is at operating range, the problems start), and I need to remove it and to send it off for a repair, and hopefully, it can be repaired.
My problem is rather trivial - out of the 6 bolts: I was able to loosen up 5 and the #6 bolt broke off my Torx 20 bit and got the inside the torx part in the bolt stripped (almost looked like a Hex, but hex key would not work on it). It is the top left one, the one that is relatively easy to get to.
I went to home Depot, they sold me some "extractor" tool for $20, that is the "best on the earth", but it did not help.
Any suggestions on removing that last bolt?
