Hi All.
Yesterday during normal driving gearbox light came on the dash and information Gearbox malfunction, you can continue driving. After scan found out that it is error code P1891. Car is driving fine. Gearbox changes gears smoothly on D but I can not switch to S and to Tiptronic ( steering pads are fine to change gears).
Can anybody had the same problem?
Please help.

Thank you.
