2015 DSG stuck in first gear

[Pfeliciano]

I have an Audi S3 that the Audi of Fort Worth dealership put in a transmission because the car wouldn’t shift out of first gear. They purchased a used transmission from LKQ once they installed it and test drove the vehicle it did the exact same thing. Would not shift out of first gear. Dealer says used transmission isn’t communicating with vehicle. Now they wants to put in a New transmission from Audi. Is there any way around this? I’m confused as to why the transmission from LKQ doesn’t work. Please help.​

That is odd and seems a little silly that the dealer would assume that two different transmissions would have the same exact problem and it's the fault of the transmission. Seems pretty unlikely to me. Honestly this is my first dsg i've owned so I really have no idea how to fix them. sounds like some sort of control module or sensor to me there are multiple sensors that detect the movement..
Maybe someone else has some idea? Also can you put it in manual mode and shift it yourself?

I can not manually shift vehicle.

The Dealer will have to check the TCU and most likely reprogram the ECU if it doesn't look mechanically wrong. These cars are very sensitive when it comes to the ECU/ Sensors and anything Comp-related.

if the dealer installed it, did you verify if they used ODIS to reprogram the mechatronic unit? this is common procedure that i would assume the dealership would have done. i would still verify it. it should be documented and charged accordingly as well.
