So was in the garage and tried the following

1. tip from Heinz the parking light turned on: No lights

2.battery measured with a voltmeter: Result battery has 13.5 V and should therefore be full.

3. The main fuse measured: 0 Ohm ... conducts and is therefore not defective

4. tried the spare key with the remote control. Car still dead

5. disconnected battery and reconnected. Everything works again 😀

I know I've read this here on the forum before that someone has solved such a problem with disconnecting and reconnecting the battery. Whether that will reset the immobilizer I don't know, but seems logical. A CX Morgan is like a computer... if it does not work, the very first thing to do is unplug it 😉 .
In any case, the parking light with the ignition off now also works again.

This forum is really great with all the knowledge 👍 A big thanks to all 😃
