It worked before and now doesn't. Retrace your steps. Sounds like something is not connected. I've forgotten to connect things. Disconnecting battery won't cause a problem to the DME. The EWS will prevent you from starting the car if the key doesn't match the car. I'm sure I've over simplified that. __________________ ...steven BMW CCA #146825 1996 BMW 328ti • 2003 MINI Cooper S • 2016 M235i www.bmwcca.org |
