How do I ever get the CCU out of my 1980 CD??????

None of the other procedures I have read about are remotely operable for me.

Surely, KISS is one principle left behind with the VW.

Very simple, I'll let Larry cover it as I'm about to hit the road for 18 hours..

I was going to ask if the monovalve is run off the CC as well as the aux pump. Mine has a relay on it already, as will the aux pump if I ever get around to it. Practicaly everything electric on these cars could use a relay it seems.

Yes, Please, Larry. I've read all the posts I could find and none seem to apply to this 1980CD.

I've got a pushbutton unit that is wedged in between the sides of the console, won't go in or sideways enough to extricate. Maybe the "Jaws Of Life''?? Can't seem to find anything else to unscrew, unsnap or pry. I'm sure I need to resolder something in there. I get clicks when I depress the top three but none lower. The fan goes only on defrost. Mini-vac pulls only a few inches of vac and drops readily on the green line. I can hear vac leak near drivers side well---I'll get that pod fixed. I don't think it will solve the big prob but a miracle may just decend. ( Engine vac pump pulls 20 inches.)
Old guys shouldn't have to do the limbo under the steering wheel.

This forum has saved my bacon more than a few times and I really appreciate the generosity of the many experienced folks who dwell here.

I have an '80 300D, which has had the black or blue large formed console frame removed. It looks like the ACC on this car could now be removed fairly easily, however I'm not sure that the connections can be seen without removing the console frame. By the way, what is that large vinyl covered foam structure actually called?

"Center Console", I believe.

'm in the same boat as you guys. I have the same CCU as in the picture, and I'm not sure how the center console comes out. Did (any of) you figure it out? Good time to replace the radio too, I guess. Thanks in advance! Cheers.

PS: tlawhorne, nice vehicles... what a coincidence!

I believe the ACC in gs sparhawk's picture is the dreaded Type II ACC with the even more dreaded - prone to leaking - servo unit under the hood. The type this thread started out with was the Type III with horizontal pushbuttons. While I am sure there are some similarities, the repair proceedure would not necessarily apply. I have zero experience with the Type II systems. I believe MB switched to Type III in 1981. Someone with Type II experience needs to help you further.

For me the first step was to remove the ash tray and any screws that hold the ash tray holder. With that all out, the radio can then usually be removed fairly quickly. the section above the ACC is kinda tricky, but if you remove the wood face plate around the ACC, I believe you can access the lower back side of the upper switch panel with a couple of fingers. You need to gently pop that whole unit out as I don't believe it is screwed down.

The wood or plastic piece that holds the window switches and surrounds the shifter is held down by a couple of molded on spring clips to the outer rear of the shifter hole area. Also there is a plastic pin that holds the lower rear part of the "wood" to the console base. This pin is WEAK and runs horizontally into the console base at the front of the "coin tray / junk tray". So the wood piece must be freed at the front then moved out to the back till the plastic pin is released or breaks off. Later result is not very good, as the wood will not stay down tightly there after.

There are now a couple of screws behind where the upper switch panel sat, and some screws under the carpet that is glued or adhered to the bottom of the coin tray that allow the top and bottom portion of what I call the "console base" to be semi free to move.

The console base is now just held down to the carpeted section below it by a number of paired metal "z" clips. These hold quite securely and the console base is really just formed plastic (urethane?) foam with a sculptured cover laminated to it. So again, be sure to locate each left and right clip pair and carefully pry the base from the carpeted section. The base has a very fragile cross section just where the ash tray base starts and where the contour goes from horizontal to diagonally up to the radio and ACC area.

Good luck with all of this. Removal of the ACC unit should now be obvious, and the various ACC electrical / vacuum pods are also out in the open for servicing.

On the '87 300d I assume that you can then get to those pesky lamps that I cannot get out from the two access holes? On my unit they seem to be welded in!! Also are there any tricks to prying the cover off?

For the W124, don't pry that cover off. Use some rubber tubing to get those bulbs out. If they're that stubborn, put some super glue on the tubing.

the replys have confirmed my fears that the center console would have to be removed. What kind of sadist would design this procedure???Engineering???

Thanks for the brain cells, folks. I'll give it a go when I can devote my full attention and patience.
