Easytronic "F" gearbox failure

Hello everyone.
I explain if you can guide me
by putting the contact of my Corsa 1.2 Easytronic I get on the f and does not start. Moving the change lever suddenly the N comes out and lets me start, this does it every day in the first start. Then you can stop and start that does not.
I did a gear cash test and I get the P1607 failure.
The car has 160000 km and I think it can be clutch wear.
Thank you
