Limp Home mode is one of the computerized components fitted in Mercedes Benz cars to detect electrical and mechanical problems. This mode warns the car driver of the impending problem that can either put the occupants or the car itself at risk when the needful isn’t done.
Mercedes Benz limp home mode is indicated by the check engine warning light, which activates when as issue erupts within the vehicle.
If vehicle acceleration becomes less responsive or sluggish or the transmission no longer shifts, the transmission is most likely operating in Limp Home mode.This mode restricts gear selection to only second and the reverse gear.
Surprisingly, your transmission can go into Limp Home mode when there is incorrect transmission fluid level or when you use bad transmission fluid.

- Reduced power
- Speed limited to 40mph
- Engine revolution limited to 3000 rpm
- Transmission won’t change gear (stuck in second or third)
- Very slow response when pressing the gas pedal

If your transmission is stuck in gear and you are far away from home, try this:
1. Stop the vehicle in a safe location
2. Move the gear selector lever to park position P.
3. Turn off the engine.
4. Wait for at least 10 seconds before restarting.
5. Restart the engine.
