In my experience, however, it's not the diaphragms inside the actuator that leak, but the "cover" that seals the actuating shaft to the plastic body of the actuator. In this case, the leak is when you try to open the doors. I've attached photographs of tonight's repair of my second broken W123 door actuator (I now have a spare). Photograph 1 shows a failed door actuator with a failed attempt at repairing with a plastic sandwich bag. Photograph 2 shows the bag of Bosch parts used for the repair (one for each actuator). The Bosch part number is 3 340 522 025. These are available online from Rock Auto (http://www.rockauto.com). Do a part number search for that Bosch part number and you'll get a search result that allows you to buy the item. They're $1.85 each and come in bags of 5. I bought 3, so 2 were taken out before it was shipped. The shipping charge is more than the part. Photograph 3 shows the Bosch part. This was intended to seal an electrical connection, with the wire coming out the small end. Photograph 4 shows the repair in progress, with a pair of needle-nosed pliers being used to hold the actuating shaft up so the seal can be forced down over it. Photograph 5 shows the finished repair and now functional door actuator. The seal is a little longer than needed but seems to work just fine.
