    Post 1998 BMW e38 750il EWS 3.3 bypass or delete or disable

    Hello everyone. My 1998 BMW e38 750il seldom does not crank, and I had replaced new starter, new starter relay, and new ignition cylinder's electric connector, but problem still remains.
    Therefore, I am wondering if the EWS system is the cause of problem.
    And, I want to know how can I disable/delete/bypass the EWS 3.3 by myself to check whether the EWS really is the problem?

    Any guideline or suggestion will be appreciated

    Thanks

    It might be possible, but I've never heard of anyone being able to do it. EWS is like baked into the system. By design. The idea is that if you don't have a key, you ARE NOT starting these cars. Anything easy thieves could do.

    On the very newest ones, you can't even hack the system to add keys like you can on ours. It's all locked down and encrypted. I guess the whole getting keys from 3rd party sources was effecting some VPs boat payments in Germany.

    If you only want to see if ews is preventing the starter to spin, you can just unplug the ews connector and short the two largest pins on one side. A 30A fuse fits perfectly. If the starter will work then, we will see more.

    Do those work? I searched this when I was looking at keys and every thread I found said it was next to impossible without major work. But then, those might have been old threads. Dunno.... If you need a few keys made this is a cheaper route!!
