I thought the immobiliser ring problem happened to certain Plus 4’s only. GDI’s.?

So far, nobody on TM with a 4/4 has recorded trouble with the ring, but only the dealers will know for sure.

Only asking....

Why would the immobiliser ring be different between the Plus 4 and the 4/4 of the same manufacturing years.

I can guess that the ECU might be different but I would have thought the steering column electrics and instrument electronics would probably be the same.

I'm asking so the immobiliser ring does not get ruled out of this diagnosis IF indeed it could happen.

Is it DEFINITE that the problem only occurs on the Plus 4 ??

Thank you all for your proposals!

We found the problem, everything works well now happy3

The starter relay had a bad connection to the socket
I had checked all the fuses for poor contact before, but not the relays.
