You might need to allighn DME/CAS if bensin
or DDE/CAS if diesel
because of battery goes flat, the EWS Tampering kicks in

no way , perform diagnostics if you can
RE: Bmw no start - spanaz1 - 07-12-2016
I cant diagnose the CAS because there is no communication
RE: Bmw no start - dieselfuel - 09-12-2016
If CAS crached this a problem...
you cant diagnose CAS because it is faulty, or your diagnose tool doesnt reach it
I suggest you try with another BMW diagnose tool to be sure before you conclude that CAS is faulty
Also check Fuses, wires before you change anything
Also if CAS is faulty, you wont hear the motor starting
you wont be even be able to switch on ign....
but if you have ign, startmotor turns, then there is a big chance your CAS is Alive...

Yes the motor turns and all is working fine just no fuel at injectors

Hi,
in the CAS ECU is a relais for the starter. If the starter is working on clamp 50 the CAS is awake. If no ignition or fuel is provided, the secret exchange between DME and CAS fails. So check your diagnoses software, maybe in most cases you only use the wrong protocoll or cable.
