Learn something every day. I didn't realize that any of the 107s had a vacuum pump.I decided to look into the central locking system which has been non-functional since I bought the car. It was a surprisingly easy fix! I found a nick in one of the vacuum tubes only a few inches away from the vacuum pump.
If I recall it is post '85 and for locking system only. Not sure if that is USA (560) only.Learn something every day. I didn't realize that any of the 107s had a vacuum pump.
That picture actually helps me! The plastic part was loose and I thought it was a cover. Now I can see it is loose AND broken - because it is supposed to be a holder for the pump! I don't think mine has the part with the screw hole any longer.My 87 Euro 300SL has a vacuum pump in the boot (trunk) for the locking system
Sits in a black rubber cover inside the right rear quarter panel, with the jack

Same here Graham, my 1979 Eleanor doesn't have one in the trunk like the later models 🤔 luckily all works still well!Learn something every day. I didn't realize that any of the 107s had a vacuum pump.
Is there some complete "wiring" schema for the central locking system? Reason for asking is that i had an alarm system added with electric solenoids for the doors and the company installing it disconnected something somewhere so the vacuum system stopped working and the company doesn't exist anymore so i can't ask them what they did.I decided to look into the central locking system which has been non-functional since I bought the car. It was a surprisingly easy fix! I found a nick in one of the vacuum tubes only a few inches away from the vacuum pump. Until I get the proper diameter vacuum line for a proper replacement, a robust application of electrical tape is doing the job for now. All three lock cylinders (2 doors and trunk) actuate all four locks (including the gas cover). Man - is that nice. I was tired of accidentally setting off the alarm because I'd lock the trunk, go away, come back to the car, and open an unlocked drivers door.
Next gremlin, if I choose to attack it, is going to be the ACC. I pulled out the glove box liner to replace the foam tube but didn't find anything else obviously amiss back there. None of the air location controls work and I either get full cold or full hot. Not sure if the latter problem is related to this loose wire I found under the glove box liner, which I think is a line for a temp sensor somewhere but I've got no idea where this one is supposed to plug in..
