I was toying with removing my ALDA and want to learn why it is different than those pictured...any help would be greatly appreciated.

Your ALDA is the same. That rubber Y connector is what's different, not sure it's supposed to be there.

That Y connector is what is perplexing me...I have no clue why it is there. Anybody have any pics of the trap oxidizer (wondering if that's what we're dealing with)?

Here's a view of where the lines run:

if your car is not a California car, there is no trap oxidizer

Is it a 60x series of engine?


The wye is supposed to be there if it is.

As far as I know, it is a 603 series (87 300SDL).

its normal


one lines go's to the intake manifold, one to the alda, and one to the overboost.

no banjo bolt

Hello,
I would like some help, concerning the vacuum system of a 1989 w124 300 turbodiesel.

Its like this: I put a OM603turbo in my 1986 w201 2.3-16valve gasser.
The engine already starts and runs, but at the moment i am connecting the vacuum system.
The folwoing i have found out:
-the vacuum pot on the InjPump that shuts the engine of
-the electric red thing at the end of the IP, which PROBABLY is enrichment at cold starts (sort of a choke, lets the engine rev a bit higher stationary)
-the ALDA thing (What exactly is ALDA? Is it enrichment for when there is turboboost available? more cc diesel injected? That way more power?)

But now my question: on the SIDE of the IP, there is bolted on a cornery thing, with some vacuumhose-attachements on it. The cornery thing is about the size of a pack of cigarettes, and it has a date (of manufactury?) stamped into it. On this engine (which came out of a 1989 car) the date on the part is 1994, and the part number begins with 140 (90's S-class)


Another question: On the drivers side fender there is a BLUE vacuum pot mounted, which is connected with some hoses to the engine, and also nearby (and connected to the ALDA, and the blue pot) a electric solenoid, with vacuum hoses and a 2-wire plug.
What are these for?

NOTE: this is a European car, so no exhaust stuff like trap oxidizers or other environmental stuff.

PLEASE your help!!

Have been searching here, and found out that the blue pot is an amplifier for automatic tranny. I coupled the OM603 to a getrag manual box, so i suppose i can throw the blue pot in the dustbin?

Electric solenoid on the inner fender wall is a thing that operates when the boost is to high (stuck wastegate) ????????????????? Is this true??????????

Electric sensor in the inlet manifold is the thing that drives the overboost solenoid????????? is this true?????


If all this is true, I only have one question left, and that is what is the thing that is mounted on the SIDE OF THE INJ.PUMP?????

The red thing on the back of the IP is the idle speed control mechanism that the EDS or electronic diesel system uses. With it plugged in and the little round control that mounts near the fuse box set on 4, it will idle at 630rpm. Disconnect the electrical plug to it and it will idle at 550rpm.
The vacuum device on the driver's side fender is the transmission vacuum control device. The electrical solenoid attached to the fender with the vacuum hoses attached to it that goes to the Transmission vacuum control device softens the shifting of the transmission when the engine is cold.
The device with the vacuum hose coming out of it on the IP is the VCV or vacuum control valve which helps control the shifting of the automatic transmission.
But if you are using a manual transmission, I have no idea if you need these things.
