[W126 Coupe] trunk lock

[Eddie]

No, the vacuum lines for the locks are run off a separate pump..conveniently
inside the trunk (by the spare tire).

 

The vacuum line under the rear seats are probably the easiest to access.but
you risk blowing out the fuel door vacuum diaphragm.

Bellamy- rather than going through the door panel why can't you get to the
vacuum line inside the engine bay.  There are number of vaccum lines right
by the brake booster; isn't one of them going to the door locks?

NON-DESTRUCTIVE METHOD WORTH A TRY TO OPEN YOUR TRUNK
 
SOME people get clammy armpits about using a can opener on their
Mercedes-Benz.  
 
I have never seen the emergency rip-cord... but here is another idea worth a
try:  
 
I was curious so I tested this on my wife's car this morning.  I
intentionally set the vacuum actuator in the trunk to "locked", the push
button was disabled (locked).  The button pushed in OK but didn't operate
the mechanism.
 
Remove the inside door panel, disconnect the vacuum line to the door lock
actuator, give the line a quick burst of compressed air.  That's it!  The
trunk lock opened.  In fact everything opened... no surprise because it is
all on one system.
 
If you do not have compressed air it is doubtful that blowing into the hose
is strong enough (I tried).  A hand pump might work.  That failing, go to a
shop that has an air compressor... remember, a SHORT half-second burst into
the vacuum line will do it.  too much pressure might disconnect the weakest
connection in the system.  Then, politely put, you're screwed.
 
It is a lot of trouble getting inside the door, and it's hard to reach to
reconnect the door lock vacuum line.  Having now done this I would suggest
cutting the vacuum line at an easy-to-reach spot, possibly at the bottom of
the door, rather than disconnect the vacuum line at the actuator.  (There is
only one vacuum line in the door so you can't really make a mistake and cut
the wrong one.)  Then I suggest reconnecting it with a rubber hose
connector.
