Good idea. The central locking is a non critical system. I should be routed correctly but can simply be bypassed with a Golf T until you have time to mess with it.

Also, as far as the engine shut off is concerned. The valve in my ignition lock failed so I bypassed it by disconnecting the brown line from the injection pump to the ignition at the ignition, and extending it behind the center console so it enters the passenger footwell area under the dash. I hooked up a mity vac to it which resides in the passenger footwell and three pumps of the mity shuts off the car. One day I might get around to messing with it but it's not necessary to the functioning of the car.

I guess what I'm saying is that on an 81 240D, other than the brake booster and the transmission vacuum, there is nothing on the car that has to have a functioning vacuum in order for the car to run in it's basic form.

If there were lines behind the VCV which connected to things other than the trans modulator, I feel pretty sure they were wrongly connected. Before the VCV Ok but not behind it.

Surely someone can send you the vac diagrams for a 240D. You might search the forum for vac diagrams; I remember seeing a lot of them over the years. You might even Google it.

In reading that thread I believe that diagram in post #8 is for a 1980 240D and not yours. I believe the vac diag in post #3 (from ToomanyMBZ) of this thread may be yours: vaccum problems>> 1981 240d Auto


Toomany MBZ - are you still around? I know your post is nine years old but do you remember if your diagram was for a '81 240D?

It looks very similar, but my car only has one 3-2 valve, that diagram has two.

The one Nate linked me to in post #8 looks the most similar to my vehicle... It's quite difficult to know though, since i'm not sure what is routed wrong, what's not supposed to belong, etc.

Well ;

As it says : the other valve and hoses are for the California E.G.R. system....

Use the single valve hose map and you should get where you want to go .

Oh, I must of misunderstood the diagram then. I have some new vacuum line coming in tomorrow along with some fuel line, so I'll be messing with all of that tomorrow.

Thanks! I'm waiting for the vacuum line to come in and some connectors (all because I ordered two Y connectors instead of one... Apparently they only keep one of each in stock at a time?) so it's going to be a minimum of another day before I get anything in. Possibly a few days, kind of depends on their shipments...

Just an update. I just got the parts in today, well technically yesterday but I was working and the office was closed when I got home. However, i'm not going to be doing anything with the car today because A) 16 hour shift today and B) it has been snowing since last night... It hasn't stuck, but it has resulted in a rainy/icy slush on the ground and everything is wet and cold. I'd rather wait until it isn't snowing/raining before I start pulling hoses and what not, so I'm going to commence with the vacuum routing tomorrow.

At the current moment my to-do list on this car is as follows.
1) Fix/route vacuum hoses properly (I'll be using this vacuum line, since as recommended earlier it fits all the fittings. In the end I think it'll just be less of a hassle since i'm not sure what lines are bad and what lines are good. Most likely the transmission line will be just a length of this hose to eliminate any issues with the current line.
2) Fix the fuel return line on the injectors. Currently they leak a bit... Okay a lot more than I thought they did.
3) Replace front fender with the spare fender I was given by the previous owner. The pin striping is a bit different but that's ok, it still looks better IMO.
4) Replace rubber on throttle linkage, adjust throttle linkage as needed.
5) Replace engine mounts. The fuel leak has caused them to go bad, so I want to be absolutely sure I have no fuel leaks before I replace them.
6) Replace/fix a the fog light. One of them is bad, not a high priority.
7) Replace antenna mast, not really a big concern at the moment.
8) Replace all four tires, swap the newest tire onto the spare.
9) Fix the small interior issues. Install a cup holder in the center console.
10) Remove and fix/replace all the locks. I think they all need to be lubed or something, they're all kind of sticking.
11) Fix the dash lights. They all seem to intermittently work, or maybe they're just crazy dim. Also fix the brake light, a wire somewhere is shorting or something causing the light to flicker or stay on while driving.
12) Lube the hood latch, replace the cable and release handle. Replace grill insert, had to brake the grill to get the trunk open (broken cable, seized lock..)
13) install a emergency trunk release on the interior of the car, to prevent myself locking the keys in the trunk... It's going to happen eventually.
14) Replace the main fan, a blade is broken. Install an auxiliary fan, the previous owner removed it for someone. Has to be done before summer hits. Not a issue at the moment since it's so cold.
15) Replace the thermostat, it appears to be stuck open. Probably on purpose to make up for the aux fan missing.
16) Get side mirrors on the car. The left glass is missing, the right mirror was never on by factory.
17) Replace/fix seat belts. Two of them don't want to retract.
18) Figure out what the plugs on the driver and passenger seat are supposed to be for, they aren't hooked up to anything. Seats a probably from a later model? Maybe seat warmer?
19) Adjust emergency brake, it doesn't really do anything..
20) Oh yea, and I need to trace an issue with the glow plugs. Not of them are working 100% so when it's exceptionally cold (like the past week has been) it starts pretty rough.

A lot of stuff to do isn't really necessary, but some of it is like the aux fan. A lot of it is just quality of life stuff, but it's a pretty long list of stuff to do... Mostly I made this list just to remind myself what needs to be done. It's not in order of priority or anything. The major stuff is going to get done first, like the fuel line and vacuum line issues (since I already have that stuff) the radiator fans are most likely the next thing I am going to do. Probably going to come from a pick and pull. In fact, a lot of my parts are probably going to come from pick and pull.

Any opinions on what stuff you guys think should be done first? Like I said the radiator fans are my next main priority since I live in Las Vegas. I really don't want the car overheating and blowing the motor up. And I'll be moving in the next couple months so I'm trying to get this stuff done in a timely manner, I know the list is big but I still think the car is worth putting this work into it!

The Aux fan is not essential to maintaining the correct engine temperature. Mine doesn't work. I've been thru four Phoenix summers without it and while the temp does rise slightly in midsummer sitting at a light the needle never leaves the 80 in the temperature gauge. So if you are worried about overheating because of the aux fan I'd say forget it. The main fan on the car though if I understand you correctly is missing a blade? That I would definitely replace, after sorting the vacuum issues and the fuel return lines. Engine mounts too probably.
