    Here you go. I would check the wiring to the coils, check for voltage and pulsing from ECU

    It still should run if the cam sensor goes but fuelling will turn from being sequential to firing every time the crank sensor gets a signal(simultaneous), have you tried a new cam sensor yet?

    Before you go spending any more money and pull whatever hair you having on your head it will be well worth having a mobile auto electrician run a diagnostic scan on your car. If there is an EWS fault then this will be recorded on the ECU as will the likes of the cam or crankshaft sensor.

    I have had both of the above faults and both were stored on the ECU.

    You may also think it worth your while to purchase your own code scanner. I use Peake Research and this is the scanner I used to obtain the EWS fault. It's only draw back is it does not work with the ABS system

    Your best bet would be to let Formula 1 electrics look at it as he is the top boy

    I had stanfields scan it first off and there were no fault codes but the crank sensor was sending irregular signals to the test computor.{by the way they have the same equipment as bmw dealers}.Thats why i went for a crank sensor first off.So dont really know

    Strange no codes were displayed despite all the issues you've had

    I doubt whether a submerged ECU would be capable of still storing codes

    Stanfields have got Autologic, BMW dealers have GT1, different machine GT1 costs about 5 million pound more

    Have you thought about letting Pete look at it from Formula 1 electrics? opposite Kwik fit
