    hello everyone im still having problems with my 1996 e39 525tds (M51 engine) after finding out my dme (ecu) was swimming in 6 inches of water and failed to start ?? lol.. anyway since then i have replaced the lift pump, fuel filter, liftpump/heater plug relay, and then a 2nd hand ecu then replaced batterys in the keyfob and then set fob to open an close doors etc but still it wont start ?? when i turn ignition on you hear the lift pump in the tank working, it says pre heating on display and engine cranks but wont start ?? i was told i have to have the EWS from the car it came off which i have but the only problem is that its the white EWSIII where as mine is the small EWSII which it located next to the ignition barrel ?? is there any way of disabling it so i can get my car started ??

    The small thing near the ignition barrel should only be the send receive box that powers the ring antenna.
    You should still have another EWS box somewhere.
