i have a 2015 ML250 W166 and the power tailgate sometimes does not open fully via the key remote. It opens a little then closes again. this is intermitent but wondered if anyone has had this.

Yep. Have the same issues. Especially when car is parked on not even surface. I have to force it with hands ti get it open.
Its not a big deal but very annoying.
Not going to take it to a shop to fix it.
Gate goes up but only to close half way. Read some where the right strut has the sensor and replacing it solves the problem. The stut is not much, 180 bucks online. Going to try it instead of dealer, 50 miles out of warranty by the way...
I have an 2014 ML 350 power gate, I went to the dealer because the trunk lid would open then after 2-3 seconds it would drop 5 inches and sometimes it would randomly close.
They replaced the right side electric strut under CPO warranty but the left side which is gas strut they said is not covered. They wanted to charge $300 for the left side gas strut + $500 labor fee. MB dealer said it requires them to remove all the panels in the trunk to replace the left strut... really?
$800 for a gas strut replacement seemed outrageous so I declined and shopped amazon, bought the left side strut MB part # 1669803664 (which replaces the old part# 1669803464) brand new original Mercedes part for $150.
When I checked the left gas strut, it seemed the oil was leaked, so I was confident that the left strut was bad.
Replacement takes 5-10 minutes, you will need a flat screw driver. No need to remove any liners or panels to replace the left side strut.
1. Open the trunk lid
2. Remove the plastic cap at the bottom to reveal the locking mechanism
3. Fully open the trunk (even though your strut may not have the full force, it will still spring extend so its better to fully extend the strut before you remove)
4. Using the flat screw driver slightly pull out the "wire" to unlock the bottom strut, then pull the strut bottom. (Test this on your new strut to understand how it works)
5. Same for the upper locking mechanism, use the flat screw driver to pull the wire and unlock the top of the strut
6. New strut, push the top portion first and lock it in place
7. Do the same for the bottom
8. Replace the plastic cap at the bottom and you're done.
After replacing the trunk opens and closes as it should.
+1 to running into this problem once in a while and totally random too. I've also had times when the power tailgate just doesn't open at all, whether I use the remote button or push the button on the actual tailgate nothing happens, then I just have to pull it open by hand. Doesn't happen often and it's just an inconvenience when it does happen, not going to bother looking into replacing/repairing anything until it starts to happen too often. I more so attribute the problem to some sort of electrical gremlins.

Out of curiosity, why did they say the gas strut is not covered? Did you talk to the Service Manager? Everything in the CPO literature indicates it SHOULD be covered. Sounds like they didn't want to take the hit. Annoying, but glad you found a cheap alternative.

Yes, I spoke to the service manager and he said its weird for him too that the electric strut is covered and the gas is not but definitely was not covered. Since they replaced the working electric strut under CPO, I just let it go at that time.
16 E550 Cab, 2003 Ram bright red crewcab 4x4 we call Clifford :)
thanks for the info. I like to be armed with info before i enter the dealership
Mine will also droop or go all the way down if the front of the car is higher than the rear... level ground ok........ so we got a weak strut, unknown if left or right is bad.....

You are the sunshine. I was looking for it a lot, was not able to find the solution . I believe in my case electric one is faulty . I will check that one first
2012 tailgate has died recently. I called dealership they quoted almost 2K to replace struts. End up getting aftermarket from CN and using this thread instructions to replace it myself - 20 min job, 200USD all in and broken plastic cups ( it's useless anyway)
