Do I have Soft Close Problem?
I have 2009 SL63 with Auto Close. Intermittently, when I close the trunk the red light on the driver's door is lit. When it is lit, I would re-open and trunk and close it and the light would go off. I have read a lot of posts regarding the soft close issue and from what I have read, when there is a soft close issue, you have to reset the PSE Pump by disconnecting the negative cable on the convenience battery to re-enable the PSE Pump (it is possible I misunderstood this). Note: I have never had to reset the PSE Pump whenever this is happening. So, do I have a soft close issue or is it something else?
In the event I do have a soft close issue, I have read the DIY FIX. When doing the fix after testing for leakage, do I need to disconnect the negative battery or pulling the fuse would be sufficient?
Has anybody with the Auto Close feature done DIY FIX? Are the steps the same for cars with Non-Auto Close and Auto Close? With the Auto-Close feature, I would think that disconnecting the cable from the switch would have to be done unless you are disconnecting the convenience battery.
Thanks

Either pull the yellow 20A fuse in the fuse box behind the seat, or dis/connect the rear battery - either will reset the pump. It times out if it's leaking, and that's how you reset it.
But first find the leaks and fix them.
