Trunk Close button stopped working

Hello,

So, the trunk Lock/Close button stopped working located at the bottom of the trunk lid. At first, it would lock the doors, but won't close the trunk by itself. I could hear the locks being locked and the trunk lid stayed open. I had to manually close the trunk. Also, I had to replace the battery upfront last month, two to three weeks ago. Ever since the battery change, I don't hear the locks click nor does the trunk closes automatically.

Anybody has had a similar issue and got it fixed?

Can't believe I manually close and lock the doors on my other cars, but this feature not working in the CLS is taking away my sleep lol.

I wonder if there is a reset procedure for it?

Check wiring harness in left trunk hinge however, since malfunction coordinates with battery change most likely needs reset using MB diagnostics (Xentry, DAS, etc.)

I see. Thanks for that. I will try to check with my MB mechanic about that and see if he can help with that software reset.

Hey just wanted to know if you found a fix for this issue as I’ve encountered it now. Was it a software fix? I’ve found mine stopped working after disconnecting the battery for some electrical work I was doing.
