    BMW 320d 2000 plate

    Just recently I am finding it very hard to start the car.

    Put the key into the ignition and turn it and all the lights come on the dashboard, turn it further more to start the car and no sound at all dead as dead, It has a brand new battery, but it's not getting as far as turning the car over. Move the key back to pos 2 so the lights are on the dash, then turn it again and the car starts. Sometime this works straight away, the other day 3 hours to get the car started. It does seem to be more apparent when you lock the car with the fob and then open the car with the fob. Recently I've left the car open over night and although it starts it's very hit and miss.

    Could this be a EWS I think it's call, a bad key or the immobilizer

    This morning

    1 : Left the car open over night
    2 : Key in ignition to the lights - lights on the dash came on
    3 : Extra turn car would not start - no sound, no nothing
    4 : Turn the key back to lights on dashboard
    5 : repeat step 3 - car fires
    6 : get to work turn the car off, and then straight back on works every time
    7 : go out at dinner time same as this morning but took 6 attempts to start the car.

    I have took the key off the keyring and banged the key on the steering wheel,,Dont know if that helps but it did start the car after the 3 hours.

    Cheers all, any help will be great....

    Dont know if this helps guys but every now and again the blowers cuts out but a new hedgehog has been put in by BMW themselves, Also I get the oil light on for 10 secs after the car has been running for some 20 secs - I believe that is a common fault IE Oil Level Sensor. The Two above has been issues thought before the main problem - Could it be the case the the Oil Level Sender now is completely caput and the car checks the oil level before it will start the car? - and by turning the key 3 or 4 times is building up the pressure? seems strange it took 3 hours two days ago to start if that's the case.

    The oil level sensor is passive, so it will only show as a yellow light and not affect anything else.
    If the starter isn't activating, try to get somewhere quiet, and put the key in the ignition and listen for a click from a relay above your knee from the EWS. This may need the first stage of the ignition on.

    A better way to test is to remove the steering cowling, and unplug the EWS ring antenna.
    Put the ignition to the run position and then plug in the ring and you should hear the click. If you hear it, then the EWS is working OK.

    The other possibility is a worn electrical switch for the ignition. This part is separate to the barrel and can be replace on its own.

    The end the end the end - long time no speak - Thanks again for your quick reply.

    Does it sound like the EWS then mate?.... if so is it an easy fix ?

    You dont have any pictures of the above do you ?

    Cheers, Again - Richard

    Also just found this on the tinternet - Could it be a faulty key ? is there a good way to check a key for faults?

    There's a couple of ways the EWS works, it'll check the key first, and then release the starter motor.
    If it is intermittent, than the coding and digital side of it is OK (once unsynced, it won't fix itself without resetting)

    That leaves two options, either the ring isn't always transmitting the signal-

    RealOEM.com * BMW E46 320d EWS CONTROL UNIT/TR MODULE/SUPPORT

    Part 3 there, with the cowling off you'll be able to pull at the plug and disconnect it.
    Switch the car to the run position and plug it back in, and you should hear the click of the start enable relay which is in the EWS box tucked up above the coin tray to the right under the steering wheel.
    It can take about 30 secs after the key is switched off before it will click again and open (block the starter)

    I know things like this have previously caused these problems, but there are two designs of the antenna ring, E36s would have a 6 inch wire on the ring, later E46s etc have a plug directly on it.


    The other possibility is the ignition switch-
    RealOEM.com * BMW E46 320d STEERING LOCK/IGNITION SWITCH

    Part 2 here.
    I know they are common to go on E39s, I've even done my own before, and the problem that causes is it doesn't make the starter signal at all.
    I don't think it's a hard job to change, just a couple of torx bits needed.

    Bad ignition switches can also do things like having a long delay before the radio comes on, or E39s would make the interior lights above the sun visors act strange.

    Thanks The End - I'll take a look this weekend and see what I can come up with and let you know how I got on. if it was one of the 3 issues you mentioned above would that be detected via INPA if I took it to an Indy ?

    You could check in INPA the status of the EWS, that will tell you if it is reading the key correctly, and it should also show you if it is detecting the ignition switch as being turned.


    A final check is to switch on things like the headlights and the radio. When you go to start a car, it will divert all non essential power to the starter, so the radio and lights should switch off as it attempts to start.
    If you see that happening, then the problem lies further away with the starter motor, but I have a feeling whatever problem you have, it's going to be near the ignition switch.

    Good advice mate - I've lost my laptop with InPa :-( - Need to get it re-installed. I have a the lead still.

    But I will try what you suggest mate and let you know how I get on.

    The End :

    Just back from a BMW Specialist, They have ran it through the computer and it's come back with EWS fault. The guy there said it was the key at fault and that would cost about 150 pound. I don't mind paying for it if that's what I need and I don't dis- believe what he's saying but could it still be the antenna ? or the ignition switch or shall I change all 3?

    Failing that (Another EDIT) lol ... Could I buy a EWS,DDE, Keys and barrel of Ebay and fit them myself ? I've seen them go for about 30 and that's with an additional key - My issue was I brought the car with only 1 key :-(

    I've had the other 4 keys that were assigned to the car disabled now thankfully :-)

    Cheers mate

    I think it could still be the ring antenna.
    What shape key have you got?

    Is it the one with 3 rubber buttons, or the diamond shape?
