    I have a 1998 540 1 and I changed the ignition tumbler today all went well and started to reassemble the car and the piece that goes over the tumbler once assembled broke . Now it won't start . Could that be the problem?

    New ignition tumbler now car won't start

    I broke the piece that has a plug on it , this goes over the tumbler , will this cause it not to start?

    Yes because it won't be able to see the chip in the key

    Welcome to the forum.
    You need part #7, which is just a coil of wire with a plug on it.

    Ditto what everyone above have already said. See info below as to how EWS & the Ring Antenna functions and facilitates starting the vehicle. Ignore the Transmitter Receiver info because your 98 model year has EWS 3.2...the TR was eliminated and its function incorporated into the EWS control module:
