I doubt the pump caused this but if you cannot get the door open you aren't going to access the trunk with the interior switch to get to the pump either. Very weird. Might try a bit of 3 in1 oil on the key itself but in any case you need to open the door or you aren't driving anywhere. I am amazed at times what strange problems show up in these cars. Best of luck on this strange problem.

You have a 16 year old car (I assume you just bought it), could have been beat on with high mileage, have a few problems ( all solvable) and then declare Mercedes the worst car. Just wow!

Fuse 71 I am guessing? if so, it's probably burned out because their is a leak and the PSE pump is running continuously. You need to fix the underlying problem, which is most likely the trunk latch. Look at the sticky at the top of the forum.

when i unlock the car or when i am in the car i hear all these clicks or nuts being tightened ... i mean are you supposed to hear all these things move and for how long?
do you think it's a line that needs replacing or is it the whole pump. i called my local mercedes dealership and they quoted $3000 with labor but they urged me to do diagnostics first. item#2308200648 or A2308000648?

When you first get in the car and close the door you will hear several noises. Some from the dash and some from the trunk. Typically the ones from the trunk are thumps. 3-4 evenly spaced on the driver side is the PSE pump. This is normal. You should also see the trunk draw down when you close the trunk. This is Soft close working correctly. Again you might hear the PSE working for a moment or two.
If if you continue to hear the thumps in the trunk for more than about 15-20 seconds you have an air leak. You seem to have already found the fuse. Remove it and follow the sticky on the trunk close repair mentioned above. Once you have the mechanism out inspect it and you will most likely see a crack in the plastic that is the cause of the leak. Easy fix.
Another spot to check for a leak leak is the air bladders in the seats. To check, get in the car with everything turned off in a quiet area. Listen closely in the lumbar and front of the seats for a hiss. Both of mine leaked. I believe due to pressure I placed on them when repairing the front roof lock cylinder.
Good luck.

If you are not going to DIY, I suggest finding a good local indy shop to work on your car. The dealers are very expensive and usually not very good at doing anything but swapping parts and making huge profits.
As for the noises, one that you might hear is the SBC (Sensatronic Brake System) charging. It will sound like a motor or air compressor under the hood running briefly. This can happen at any time when the car is "awakened", which happens when you open a door. This is totally unrelated to the PSE (pneumatic) system used by the trunk latch, door locks, interior compartment locks and the seat lumbar adjustments. This pump is located in the trunk, inside a sound-deadening box. You will hear some clicking noises from the latch when you open and close the trunk, and you may hear a very faint sound of the PSE pump operating, and even some "swooshing" sounds of it pumping air. These are all normal sounds.
Note that if you hear air blowing sounds for more than a second or two after opening or closing the trunk, then you have a leak in the latch (which is very common) and should be fixed.

great point there. for sometime the seat lumbar support hasn't been working. so ? it is the PSE pump? or one of those yellow lines that needs to be replaced?

typically it is the seam of the air bladder that is leaking. Without replacing, the best and quickest fix is to cut the air supply line to the seat and plug it.

Wow, I've seen one other case of this posted int he forums. I think it's caused by a failed pressure which allows the system to be over-pressurizes and it snapped the pulsation dampener off. It can be fixed, though you'll also need some body work.

i would also like to give an update on the implosion that happened to my car two weeks ago
it was the pulsation regulator. the THIEVES lying scum CKSUCKERS at mercedes told me it was the ABC pump and the valves that need to replace without even giving a **** to investigate what was really wrong or what happened they wanted "$5000 to start". ABC pump was fine the pressure valves were fine too.
