My US spec 2000 VW Cabrio MK3.5 has the 6H0953257B Siemens immobilizer. I 've been trying for a while to get my PIN with other methods, but it was impossible. I ordered a TMS370 programmer, and a spare immo box from ebay so I can practice with before I operate on the original box. Somehow I think I created a short when the TMS370C702 was on the programmer and it got erased. The first time I run the TMS I got the PIN 7404 but after that when I was running it again I was getting 65535 which makes no sense. Reading the EEPROM I get all FF's. Does anybody have a backup of this file, so I can load it and make sure that I have everything working before I operate on the original box?
Thanks in advance.
