I made a new key on a F15 X5 yesterday and the result was weird to say the least.
-BDC had to be updated on bench before the unlock
-BDC unlocked without issue using original key
-Made a 2nd key.
All was fine until reinstallation in the car;
Engine could not start with either keys, tons of errors message on the car information display.
I figured the module was not coded properly after the update, however AH did not let me code the module, both gateway and BDC gave a message of no coding available.
I had to fight with E-SYS (because the SVT was missing after the update) to manually detect a good CAFD to recode the module.
After re-coding with e-sys the engine started with no error message.
Now, unless i'm missing something, shouldn't the module get recoded properly on the bench after an update ?, no reason not to, as it already contain the VO to code it properly. If I wasn't used to coding with E-SYS that car would still be in the service bay, not starting, and with a very angry customer... 😛
