R231 SL550 power close trunk failure
Hi, first time poster, have a 2013 SL550 with troubles closing the trunk. Hope this may be a known issue but having trouble finding any specific advice that addresses my situation, thanks if you can help!
No trouble opening
- Trunk opens properly and fully whether using remote, pressing the release on the trunk itself, or using the switch inside the car.
Upon closing, closes a few inches and stops
- Same deal - doesn't matter how you do it, same results whether button or remote.
- No errors shown on the dash - it just stops
Once it's stuck
- If you press the trunk button again (no matter which), you hear a brief motor sound. Then two brief motor sounds a second later. Bzzzz, pause, bzzzz bzzzz. But no movement.
- Now you have to force-close it manually, press it fully shut, it will latch.
- Now you can open it again normally using any trunk button. But when you go to close it, repeat the steps above.
What I ruled out
- Top up or down - does not matter. Exactly the same symptoms.
- Since the top is able to fully close, and no trunk divider errors are shown, I think we can rule out trunk divider problems
- Car running or not, no diff, just ruling it out academically
- I pressed the green escape button a few times as this was said to perhaps reset things, no difference
- I cycled the lock mechanism by locking with a screwdriver, and unlocking it with remote and also used the emergency key to exercise the physical mechanism, works good,
Any thoughts? Sure would like to hear some things I could try. Thanks a lot!

Also, if there was an obstruction that blocked it from fully closing, instead of stopping I think it would reverse course back to fully open? I have not tested it with my arm to be sure

If the limit point is recognized via the signals from the trunk lid position sensor (rotation angle), the Vario roof control unit stops the actuation of the trunk lid solenoid valve and the vario roof actuation hydraulic unit electric motor.
If the Vario roof control unit does not receive signals from the trunk lid position sensor, the actuation is stopped as well.
or
Calibration lost
or
you must do a proper diagnostic scan
Xentry allows you to see all values and faults
There is a large preconditions list in test. That will tell you
