2005 Mercedes SL350 - the soft close on the boot no longer

Customer Question

2005 Mercedes SL350 - Hi the soft close on the boot no longer works. I can still shut it with a 'slam'. I can still open it with the door switch and the key fob. Roof seems to be working fine. Is this a sign that the PSE pump is failing? Should I invest in a new pump at this stage?

Hi, welcome to Just Answer. My name is***** does not sound like a bad PSE this sounds like a leak in the trunk lock actuator that pulls the lid down. Since everything else is working the PSE should be fine. When the trunk lock actuator leaks the PSE will turn off the vacuum to that circuit in order to protect the PSE. Replacing the trunk lock should cure that problem.
Let me know if this helps.
