Hi,
I'm a proud owner of a 1983 300D Turbo Diesel Sedan here in Northern California and have read just about all there is (obviously not perhaps) regarding the Alda adjustment and Banjo bolt clean-out but I haven't a clue as to where these two key components are. I know where the Alda itself is and assume the adjustment screw is under the four slotted screws- ? If anyone might be able to provide pics of these items I would greatly appreciate it!
Thanks for providing a wealth of information on this great site and to all those who contribute as well!
Thanks,
Chris R.

The ALDA ajustment screw is not inside, but under the CAP in the middle of the ALDA housing. Take a lot of time to remove the cap, it can be very difficult. Unscrew the nut abit and back out the screw (counter clock wise) one half turn at a time and lock it back down, until you get it were you want it.
The bango bolt is behind the intake on the passenger side of the car. There is a clear, or not so clear hose from it to the ALDA.

Is there a special tool the dealers use to manipulate the locking nut without destroying the surrounding shield?

No. It's a tamper-proof seal. Once the black plug is put in at the factory, it can't be adjusted without destroying the seal.

There is a way around it. Remove the ALDA and put a thicker washer under the ALDA.

Or better yet, don't mess with it.

...if you don't want your car to run better.

Where exactly (more or less) is the factory setting? Somewhere in my cars history someone has mangled the shield around the adjustment. I'd like to go back to the factory setting so that I can play with it from there, or go back to it if I'm not satisfied. Oh yea, mines a 1985 300CD

Doesn't matter anymore, really.
Adjust it so that you get good acceleration without smoke.
Factory setting might be just a tad leaner, but diesel's energy has slightly changed, and wear on the car might necessitate a richer setting.
