Renault megane2 dci 2006

My instrument cluster only works when I disconnect & reconnect it. After it works fine all gauges are working. But when I turn off ignition, close and lock doors it doesn’t come back on unless I disconnect and reconnect. I had a ecu replaced and a fuel pump. After I have this problem. Don’t understand. Its power & contact or it wouldn’t work when I disconnect & reconnect. Need some help here.
Thanks



If I had to guess I would think a loose ground. But you may need to check the wiring harness and connections alike. Did this start happening after you had the ECU replaced? If it did there may be the need to update the software.
