2006 750LI trunk release button issue

Hi

My 2006 750LI trunk lid release button on remote has started giving problem lately.

1) sometime it will require many attempts on the remote and the trunk lid will open
2) sometime it wont open even after trying multiple times to open the trunk using remote
3) sometime I can open the trunk by hand pressing the rubber handle on the trunk lid other times that will not work either.
4) I can always open the lid using the key.

Please help resolve the issue.

Any help will be greatly appreciated.

Thanks.
Vinod

Opened the trunk and closed/opened the locking system manually just in case there is a friction in the locking system. It works ok during that time but fails to open using remote after a while.

Please Please HELP!

So when you press it, nothing happens or you can hear some noise and it stops??
Most likely you have a hydraulic cylinder leak and low on fluid.
Get new cyl kit and shocks.

YUP. It makes a noise and tries to open the trunk but unable to do it. I open the trunk using key and manually lock it while the trunk is open and sometime the remote key can open it but not always. So there is some issue.

If I get Cyl kit and shocks, it it easy to replace? can you point to some instructions/videos?

Thanks and appreciate your help very much.

Thanks for your response.
Since I have auto open feature, I assumed the trunk should open when I press the button on the remote. I have not tried to force it. I will try and let you know.

if you are able to pull it open , Then the problem
could be your low on hydraulic fluid , Or your
springs are just to old & worn .

All:

1) It does not seem to be remote battery issue, as the behavior is same when I try to open the trunk using the truck open button from inside the car.
2) My trunk opens perfectly fine with the key it is only the issue when I try to open using the remote or using the button from inside the car.

Please review and help me resolve the issue. Taking it to BMW may means atleast $500 expense

Hi

I need your help to resolve my issue. Here are the diagnosis I have done:

1) Not a bettery issue on the Key FOB, as the same behaviour when operating using the switch from inside the car
2) Center console switch is already on

The symptoms are:

- The trunk will not open using button on the remote or the button on the trunk.
- It makes noise and try to open the trunk but the locking system unable to move the latch completely
- I applied WD-40 on the locking system but did not help much
- The trunk opens sometimes when pressing the key 4-5 times on the remote. But the results are not consistent. When the trunk opens, it opens nice and smooth. The issue seems to be when the button is pressed, it does not unlock it all the way.
- using the physical key, I can always unlock the trunk without any problem and it opens nice and smooth.

My car is about 9 years old but the miles on the car is 47K.


Do you think it is low on hydraulic fluid issue on the cylinder?
Please help.

Thanks.
Vinod
