I have a Mercedes S500 2001 and I have problems with the doors not willing to open once in the wile, looks like with temperature start dropping down I start having issues with trunk driver door and both right side doors some times some of them not working I should some times some of them working. It dose looks like there is no enough presser coming from the pump.
Can it be a leek some were?
Where is the pump located?
Is there a vacuum storage?
Thanks in advance for all your help.

Try the fuse first. If you have done this than the problem could be in the actuator on the trunk latch. Poss loose/bad wire or faulty unit? I hope this helps!

Hi there
First of all may i say i feel your pain. literally. the same thing happened to mine. here is what i did
Firstly i needed into a locked boot urgently (for wifes wheelchair)
so i cut a rectangle out of the boot put my hand in and pulled the release mechanism, that worked but left me with a hole in my boot.
I suggest that you try this instead.
remove back seat
the central locking pump is located next to the battery (black box with yellow air lines going into it.)
Unplugg the filler cap cover air line, then unplugg the boot air line and put it into the filler cap cover socket.
now when you unlock the car the boot should automatically open.
If it does not the problem it on the boot air line and you should strip the trim out of the boot to check, but you still have to get in and may have to do what i did initially.
If changing the air line worked then you will soon get tired of having to shut the boot everytime i solved this problem by routing the filler cap air line to a pnuematic switch (LEGO) This switches between the boot and the filler cap. bit naff but it works and cheaper than having to replace pump and have computer and keys re-coded total cost around £600.
op that helps

Your trunk lock actuator is probably in valet mode. Take the mechanical key out of your smart key(should have a release button on the bottom of the key which will allow you to slide the hidden mechanical key out of the plastic housing) insert it into your trunk lock actuator and turn to change your function of trunk actuator. In the valet mode the trunk does not respond to your central locking or release button commands. Your owner's manual will tell you about these features. I hope I have been helpful

There are 2 pneumatic pumps in your vehicle. one is vacuum and is for your central locking, located under your rear seat bench. The other is pressure and is called your closing assist pump. It is in the trunk behind the rear liner. It also operates you reverse antennas(optional). Your doors and trunk lid are closed by pressure valves that work like little teeter totters. There is an updated relay called a convenience relay located in the right side of the trunk. It stores all the window paramers(for express up and down) as well as your closing assist parameters. In the right side of the trunk there is a fuse box. If you remove the closing assist fuse( I beleive it is # 15) for 15 seconds and then reinstall it, the parameters for your closing assist will be reset. It is possible that your vehicle already has the updated relay(called a relay but actually a microprocessor) and there is a leak in the system. After reinstalling the fuse you can see what doesn't work( one of the doors or trunk,reverse antenna) and isolate the faulty component. If everything works o.k. let it be because they have always been problematic and when they happen to fail just reset it. hopefully I have been helpful.
