Mercedes-Benz A150 Autotronic Malfunction

[Stan2004]

Hello everybody,

We've got an 2005 Mercedes-Benz A150 with Autotronic here.There's a very
strange malfunction with autotronic gearbox - when I try to start the car (turn key to I position from 0) and the gear selector is in "Parking" position - the board computer shows message "Engage N to Start" and instrument panel is showing that transmission is set to "Drive" while gear selector is being in "Parking" position.Moving the transmission selector does not change the situation,in Neutral,Rear and Parking positions instrument panel shows that it's set to "Drive".

Transmission fluid is OK,no internal or external gearbox damages,but local dealer serviceman says his diagnostics computer shows an very uncommon error message,he meets for the first time.

I would be very grateful if anybody will post about possible reasons of this problem here and any ways to solve it.

Thank you

P.S. It's impossible to start the engine.
