    My 2009 Cooper S had to get jump started. I drove it to an appointment and when I came out, it wouldn't start. I had several people try to help me jump start it again with no success.

    I towed it home (more like drug) and after some basic troubleshooting, replaced a low battery and the relay for the fuel pump. This did not make a hill of beans difference as it will still crank but not start. I can hear the fuel pump prime. The engine cranks like a champ. In the Tach icon window, it displays a key symbol (no checks or other overlays).

    I bought a Foxwell 510 Scanner and can't make heads or tails of the results.
    i.e.
    Diagnosis index: 1696

    A102 CAS: Immobilizer anti-tampering protection present
    2FD7 DME: EWS anti-tampering protection present

    I would really like to start driving my Mini again. Any help would be appreciated.

    I believe immobilizer is the key word to your problem most likely brought on by low battery and battery replacement. If this is the case you’ll need to register your battery with cars computer. I wish I could be of more help but I have an early R53 and it does not have that feature.

    It sounds like you are out of sync. I believe the key and BCM has to be in sync. Some times with a low battery they can get out of sync. It will have to be reprogramed. I believe only the dealer can do this but perhaps a good independent shop can. What part of the country are you in maybe someone here knows a good shop

    Also your battery may need to be registered this just helps with the smart charging system. It won't fix your problem but your Foxwell scanner can do this.

    Welcome to M/A Trevor. Sorry about your issues. Let us know where you are & we may be able to point you toward a competent shop.

    Man I love these new modern cars, when they work.:Dead: I'm very glad I did a proactive battery replacement on our MINI. Maybe I dodged a bullet. :Nailbiting:

    Thank you for the suggestion. I'm in the Phoenix/Laveen, AZ area. It would be a whopper of a tow bill if I have to take it across town to be reprogramed. Any suggestions from the group would be helpful :)

    I was able to at least register the battery replacement and verify all but F31-35 give me voltage across both test points
