the "new guy"
Hey all, just thought I'd say hi. I have an '87 300D turbo currently. I just sold my 5 spd manual '86 190D and "upgraded" to the '87. I have read all previous posts here but was still wondering about something that I know ya'll have discussed. My locks are slow to open, and I know it's something to do with the vaccuum....but what? What would be a good fix and a possible cost to me? Thanks to all of you, I'm extremely excited to have found this!

Locks
Welcome to the Forum!
You probably have a leaking lock diaphram - Have you purchaced a "Miti-Vac" yet. You will find this to be an important part of your arsenal. You will need to trace down the source door by door (and not forgetting the trunk and fuel door if applicable). I believe the yellow is the supply line and the yellow/green is the unlock. (If I am wrong someone will chime in). Do a search on the forum "locks" or "lock leaks" and you will find a day worth or reading.

In the W124 chassis the vacuum source for the locks is an electric pump under the rear seat. Buy a MityVac and start your troubleshooting there. Follow the lines, pull the rubber connectors at each branch and see if the line will hold vacuum. Just keep chasing until you find a cracked line or leaking diaphram. I would say trunk and fuel filler are more common leakers than the door locks.
Every person who buys a Mercedes should immediately buy a MityVac. They are indispensible.

Usually if it is a leaking vacuum servo, in addition to a generally slow locking operation, you will also be able to find the leaking component because it will usually lock last. You may need some help identifying this if the door all lock at the same rate because you will then need to watch the pin (locking pin) of the gas door (just watch it with the fuel flap open as someone turns the key in the lock cylinder, and also try to observe what the door lock knob are doing), and also you somehow need to check to see if the trunk is locked. Just watch when the door lock knobs are down, and the second they are down, try to open the trunk.
If everything is working evenly, I'd suspect the electric pump is worn out, which you do see fairly often on an older one like this. On this system, there is only one line running to each servo, the pump provides vacuum to lock and pressure to unlock, all using the same lines. Gilly
