SID message “gear defect”

Drive a 9-3 Aero Jg. 03 automat with 40 tkm When I wanted to start today, I could not change the gear from the parking position “P”. Also the pedal lamp next to the switch knob did not light up. Then I turned on my baby again and see, I could switch from the “P” to the “R” and then to the “D” and start driving. But on the SID the three-line message always appears:Greeting defect Power reduced driving Next workshop to visit tomorrow I will go to the workshop after d ask the problem and make an appointment if necessary. Did you want to know if you have experienced something like this? It can’t be that after 40`000 km the gearbox is defective. Thank you!
