The EWS "Green Box", was this the module located behind the glove compartment or the module just inward of the driver's side footwell? Reason I ask is because the module just inward of the footwell is for the ews antenna ring that goes around the ignition cylinder. Those have to match as well ie; if you swap the antenna ring, you have to swap the module. However, you can use your old antenna ring and your old module. Marv17 had ews issues and I traced it down to his uncle swapping the ews module located inward of the driver's side footwell. His car started when he placed the M3's steering column on the floorboard of his ti(because the M3's steering column still had the antenna ring attached to it that matched the module his uncle swapped). Swapped his old module back in and the thing fired up no problem. Man, I hope it's something as simple as this
