Does the car have a sunroof?

The problem you describe, is pointing toward a defective EWS3 immobiliser.

I can certainly assist you, however I would need the immobiliser to be removed from the car, along with the DDE4 ECM and posted to me.

To remove the EWS3, you will need a Pentalobe TS30 security Torx Plus bit, these are five point as opposed to the usual six.

A cheap set can be found HERE

The EWS is located behind the light switch, bolted to the A pillar, and looks like this.........
