Take it to a transmission shop and have it repaired.
If it's in limp-in mode you need to take it to a transmission shop and have it diagnosed.
It is in limp mode because there is a serious failure in either the transmission or the control module.
Mercury Villager was created in 1993.
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.
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.
