Help my V8 mutates to Tiptronic

moin moin from Switzerland. I'm called mario and have finally bought me another dikken. the following problem he has I can only drive to 1 and then put at 10 kmh on d. switch it clean and flawlessly up as well as down, moreover I can no longer put in p select lever on p but in AI it is not shown and roll it also does on position p. If I want to switch from 1 to d I have to switch half on n and then on d so that he understands what I want from him, the dikke is born in 90 and has glided 168000 km across the road.

thanks for replying your mario
