    Hi everyone, i am new to this forum but could really do with your help !!!
    I seem to be having a problem with the EWS 2 system in my M3 and want it gone.
    At first we thought it may be a problem with the Clifford alarm system, but that has all been given a clean bill of health today.
    So it all points to the EWS 2 and the local BMW will not help other than charging me £118 + vat to diagnose and then replace the EWS and reprogram the system

    This all started after i broke down and the recovery company played around under the bonnet ant removed the battery from the boot.
    At the week end i had several occasions when the lights on the dash all lit up but would not crank or prime the fuel pump. After several attempts i managed to get it going but it final gave up completely on sunday!!!!!

    I am aware that there is a work around as the dealer confirmed this was true , but are not allowed to do it as they will get in major trouble with BMW.

    if anyone can advise me how it is done i would be very greatfull, as being a woman driver it can get very embarrassing/ awkward if i get stuck any where, especially at night

    P.S. I might be a woman driver but i am fully qualified and time served mechanic, spent the last 5 years working on Subaru's and running the work shops (yes i know, a very rear thing to hear, there arent many of us around lol)

    looking forward to your replys

    many thanks

    Carol

    I'm not sure if it is the EWS, but I am able to remove it from the ECU which is half the battle. It might still need some little bits of wiring afterwards though.

    The simplest thing could be a loose battery connection, if it makes poor contact, it might only be able to give enough power to switch on the light and the radio, but not to crank the car.
    BMW EWS rarely goes wrong, and when it does, it stays wrong, it wouldn't start later.

    Some sort of fault code read would be handy to point you in the right direction.

    Could be a bad earth connection on the battery. Why did the recovery firm remove it?
