Newsletter Number 26

Hello and welcome to another newsletter.

Well, we have got all the stock from Tamworth packed away now. It was a much larger task than first anticipated. The sales brouches were certainly a hit with the newsletter readers as we have sold heaps of them. We have taken the chance, whilst putting all the stock away, to redo our parts clearance page. A preview of the page appears below.

John Green.

Any questions? Or you want to get off the list? E-mail us here.

Whats up with the website?

Have you noticed that we still have some hassles with the site?? The MBClub page for the ACT is still off on holidays and there are a few other problems. I have tracked it down and will be fixing it as soon as I get this newsletter out. The problem is to do with the compatability of our new server and the various web browsers out there. Most of our pages have a URL with the file extension .htm. It appears that to be fool proof you need to use the file extension .html. No idea why this was not a problem for the last four years but now it is. I have to change all the file extensions to .html and all will be OK according to the tech guy at out ISP. (Lucky I am better at fixing old Mercs than computers!!!!!)

Central Locking hassles?

After last newsletters heater hassles clinic I have been asked to do a quick run down on the mysteries of the central locking system. So here goes............

There are two types of systems used in MB cars. Both use either vacuum to make the buttons go up and down and the later version also uses pressure. Lets just look at the early vacuum only systems first. These instructions apply to the following models W108, W109, W115, W114, W116, W123, W107 up to 1980

All petrol engines create vacuum in the inlet manifold and all diesel engines have a separate vacuum pump. If you have a look at your car you will see a large pipe running from the inlet manifold (or pump) to the brake booster on the fire wall in front of the driver. Depending on what version you have, this line may also have a small line connected to it. Or there will be a second much smaller line coming from the inlet manifold. This is the source of the vacuum that runs the central locking. If you find that it branches to a heap of lines the one you are looking for is the yellow one. So therefore it is also the first thing to look at. Check that the lines are secure and that there are no leaks.

But the central locking works with the engine switched off??? Yes it does. There is a vacuum tank in the boot (or behind the fuel tank on wagons). You will notice that the yellow line spilts into two in the engine bay. One line goes to the tank and the other to the master valve. The line to the tank is normally yellow with a black stripe. Check that these are all in order. You will also notice that there are some one way valves in the system. Check that thay are still one way valves. If the engine has back fired at some time it may have blown these out. If you have a vacuum gauge you can test the vacuum tank and the lines that run to it from the engine bay.

Next step is a bit more involved. You really need a vacuum gauge but can do without if you are tracing a big leak. The plain yellow one goes to the master switch on the drivers door. From there it is sent to the unlock or lock side of the actuators in the doors/boot/petrol flap depending on what position the key is in. The vacuum switchs are normally not the fault so you are better to find the white and black lines (lock and unlock) that come out of the drivers door and trace then as they snake around the car. You can use your vacuum gauge and test the doors without pulling the door trims off. Otherwise you need to pull each door trim off one at a time and check them. Sometimes you can get lucky by watching which door closes last to find the weak/leaky actuator.

Hope this has helped.

Site of the week.

The weeks site of the week has been sent in by Mark Waterhouse it is a great W126 site from the Netherlands. Have a look here to check it out. The navigation buttons on the left are the same as the switchs used in the console so someone has a great imagination and the tech abilities to do things like this.
