SOURCE: easy in/out function on Mercedes E350 doesn't work

I will try to help. If the function is to move the seat automatically for entering or exiting the vehicle, then this function is often on a Menu list. Sometimes when an oilchange place resets the oil change interval, the wrong button gets pushed and wipes out the settings for something else, like your in and out assist. It may also happen if the Battery was disconnected.

Now if the power to the seat has a broken fuse, you should check your sseat controls to see if they still move. If not a fuse needs to be changed and a repair made. The loss of power to the seat motor is the reason the automatic movement does not work.

If the steering wheel and column is also tied in to easy access, it may be fused separately and still work.
