You need to have the faults in the transmission read.

It goes into limp mode when the computer detects a problem and sets a code. Have it checked for codes.
Limp mode is what the car goes into if a major sensor( like a cam sensor) fails, the engine will run at reduced rpms and with power reduced.
Transmission is in limp mode and most likely it is the input or output sensor or a wiring problem to one of them.
Your car is in limp mode. Limp mode is a safety mode your car goes into when you have a problem so you don't blow your engine. Its usually a distributor problem a map sensor or a timing belt problem.
Most VW's only go into limp mode if there is a very serious problem. Limp mode is there to protect the engine, not to be an inconvenience. To disable limp mode would be to allow the engine to self destruct.
The engine will go into "limp" mode and it will turn on the check engine light.
Because there is a problem with engine or gearbox etc. Limp mode was designed so you can still drive your vehicle with just enough speed to get it up on a lorry for repair.
Limp mode or (limp-in mode or limp-home mode)occurs when your computer in your car is not communicating with the sensors on your engine. On some cars(volkswagon Passat for example) If you disconnect the battery then the computer will lose all of the settings and will go into limp-in mode. The car will have little power and a top speed of only about 30 miles per hour. The function of limp-in mode is to get you to a place that can repair the car but the car is barely driveable.
You have to repair the cause of the code that put it in limp mode.
Limp home mode is just as it sounds. It goes to a preset load of values to allow the car to get you "limp" home or to the repair service. All engine and transmission performace is reduced. There is no such thing as a "turbo limp module".
