I have this automatic trunk, and now when i try to open it from a car or from a remote it opens just a half way... my car is 10 days old...

But anyway it's kinda my first problem so far, Also drove today on some snow with Stock 265 contis wasnt as bad as i expected the car drove pretty well the ESP system is pretty good in this car!!

Anyone else had some problems with theirs 2004/05?

with my '04 you have to hold the button down for a couple seconds for the trunk to fully open with both the key fob or interior button.

BoBcanada

well from interrior I hold the button but it still stops half way! And fromt he key in 05 i guess you dont have to hold it all the way, It used to open by itself.

You have something wrong with the springs or the motor in there. I would surely take it to the dealer and have them see what is wrong with it.

You accidently programed it to "limit" on the computer. Turn the limit "off" and it will go all the way up.

BoBcanada

Hmmm maybe, coz i was playing with setups in the menu. I'll check there for the limit, but i doubt i saw somthing about the trunk there...

If you doubt it, take it in for service, I'm sure the techs will have a good laugh about it.

I'm quite certain it's a programming issue and not a part failure. The auto trunk is designed so that you can limit how much it opens.

I had the same problem BoBcanada and thought it was normal but when I took it to the dealer to install a tracker on the car the service rep commented about it and asked me if I wanted it to open all the way. Obviously, that’s the way everyone would want it in my opinion so he did fix it. He linked a computer to the car but in the end I think he was able to do it via the cars computer.

Use your steering wheel and go to setting to remove the trunk limiter than it will open all the way.

I had this happened to both of my W211. I did not recall ever setting them on limit. But not long after the car was delivered, it simply went into limit mode. After removing it, the trunk operation has returned to normal and so far it has not happened again.

Mine died completely on my E500. I am taking it in tomorrow. It makes noise when you try to close it, but nothing happens.

BoBcanada

I fixed mine, as someone said you can put a limit to it through a Dash computer, i guess I played with it yesterday and it switched to a limit, Today i just turned it off and its back to normal ! Thanks guys!

I had the same problem but fixed it in the menu.

Hello all,
My problem seems similar, but...
When I try to open the trunk on my 2006 E500, the trunk opens half way, the red CLOSE button light goes off. If I press this button to close the trunk, nothing happens. The only way I can close the trunk is manually. I know for sure I did not change any settings. To be honest I don't recall seeing such a setting. Can anybody tell what menu it is in?
Thank you.

I had the same issue and symptoms with my 07... had to take the trunk liner out to get to the wiring on the driver side. Along the arm that goes to the trunk lid, you'll see the wiring running along it held on by zip ties. On my car, the last zip tie(closest to the passenger compartment) had worn through one of the brown(ground) wires in that harness. Spliced/soldered it up and it was good as new.

Hopefully this helps some.

Hello zwhill,
Thank you so much for your advice.
Any advice on how to remove the trunk liner nicely is greatly appreciated.

zwhill

Without having it in front of me, I couldn't. It's fairly intuitive though.

akarpovich

What I meant was how easy it is to remove it without damaging. Is it secured by some plastic clips that are easy to brake?
Thanks.

zwhill

Not that I recall. It was fairly easy to remove. If I remember correctly, there are a few screws fastening the hard plastic trim piece, along with a few screws on the liner.

akarpovich

Thanks a lot.
I'll update you on my progress Monday.
Have a good weekend.

Hello zwhill,
Thank you so much! You were right, the brown wire was broken.
I fixed it with the crimped terminal. Now everything is working fine.
Thanks again for your help, much appreciated.
Alex.
