Ignition lock spring or contact part defective ?

Hello.
just got the HU/AU new again.Of course without defects.
When I was proud to go home, the starter suddenly turned along, but only in selective lever position N and P.
The sound reminded me of my transmission and I didn't think again...
Directly, the horror thoughts came to me again to a new gear change.
Then I realized: no blinker function, air conditioning, etc.
Then I turned the key a little back and look, everything was OK.
Everything except the switch for the functions of the program switch for the transmission.It can no longer be moved, as if no current is received.
Now there are only 2 possibilities contact part or the lock or. the feather.
I think it's the castle.
Who knows more?
Greetings Andre
