Automatic open, close tailgate function.

What else is there to do - I have changed both dampers up under the ceiling, refilled with new hydraulic oil in the servo motor.

The tailgate opens and closes without problems when I help it at first movement by activating the handle.

On the left side, the tailgate opens approx. 1 cm., but not on the right side.

When I help, by using the handle, everything works fine.

I can hear "something" that is "working" but.......

Your tailgate pump is low on oil.

Timo Schroeder

No, unfortunately not - I've just filled, flushed with new oil - it doesn't change anything 😕

I have the same issue, and I believe the latching mechanism is sticking.

Timo Schroeder

Ok - I can see that a lot of people have the same issue. I've been trying to find a technical drawing, sketch or similar of the whole system, but so far without any major success. I'm pretty sure, it's just something simple small issue, but there to start....

Timo Schroeder

Could there be something like a "sensor strip" as on the w164 ML class?

Then its time to replace the pump.

Pump working ok, it's not the prothem.
