Mercedes 114 115 Sedan Door Lock Diaphragm Kit

Here is a great way to save some money repairing your 114 and 115 sedan vacuum door lock actuators. (Will not work on 2-door coupes). When they go bad it is almost always due to cracks in the rubber diaphrams. These can be easily replaced once you remove your door panels. Sold in sets of 2. Two are required per actuator and you have three actuators in the left rear door and both right side doors. No instructions included by replacement is straightforward and self explanatory.
