    ews swap

    Have a 1997 BMW 528i it belongs to my wife she had an accident. Now the engine is going so I am replacing the engine. but they wont touch it till they see that the engine turns over. The car has sat for 10 years I jumped the ews so that the starter would actuate. The lights come on when the key is in the ignition but no crank. have not changed engine yet. wondering if I swap the dme ews and key of 2003 x5 would it work any ideas anyone

    Not sure why "they" care if an engine about to be replaced will turn over but all you need to do is put a wrench on the crank pulley bolt and give it a turn, or not. If "they" can't figure this out you ought to find a new "they".
    Randomly swapping components of the EWS can cause trouble requiring recoding. The instrument cluster may also be involved, swapping those around results in a tamper dot on the odometer. Others here will know more but I'd not be swapping EWS stuff until certain of an expected outcome.
