My 92 has the same plumbing as your 93. My 91 looks COMPLETELY different.

That sounds like a dichotomy If you can guaranty no more than 14 psi of boost then too much boost isn't going to damage your engine. The only real risk is the wastegate sticks closed and you hold your foot to the floor too long. If you're really worried, hook up the overboost switch, grab one from an earlier car if you don't have one, to a bulb and buzzer in the cabin.

OK, I am all set for now. What I have done.
I removed the ALDA and plan to leave it off at least for now. I think if I drive with some sense I'll be OK. I have a boost gauge and the pressure swap on my turbo that begins to dump the turbo at 14 psi. I took it for a 30 mile run today and just love the car. I am not a lead foot and fairly well in tune with the car so I am going to chance it. Since the ALDA is off, I just hooked my turbo wastegate pressure line into where the ALDA used to take it's signal from the manifold. Very simple and clean. I'll need to keep any eye on that connection to keep it clear of crap from teh manifold. Here is a quick topside view youtube video of what I have currently. Mercedes turbo - YouTube Long term (the next glowplug change probably), I will have the manifold cleaned out and now with the EGR gone, it should then stay nice and tidy. I'll also probably put a nipple for the pressure signal over on the flapper tube section or possibly at the EGR flange if I remove that and put in a cover plate. Both seem like superior places than what I have but for now this will work I think. So what caused my problems in the first place. As some suggested, my ALDA was NOT getting the boost signal as I had erroneously assumed. When I pulled all the plumbing out, I found the line was completely clogged. There is a small green hose connector in between a straight line from the intake and the Y in the line that goes to the ALDA and the B5/1 pressure sensor. That connector is the smallest point and was chucked full of the manifold residue. Here is the whole set up, not sure if you can see that connector or not. It's right between the two metalic hose clamps in the pic. I cleaned it out with some brake fluid. Here is what came out of that! I guess it's no wonder it didn't work!! |

This one has 146K on the clock. I've had it since 73K. It seems to have enough maladies that I wonder if the miles are real but maybe it's just because it's a 20 year old MB. I don't know, it's been getting 32-34 mpg consistently so I just use it for a daily driver. I kind of like driving an old car that isn't worth much, that I can fix and that I understand alot of what's under the hood and whatnot. I don't care much if I have problems. Just gives me something to do and learn from. It's also a good conversation piece with my colleagues at work. They all drive BMW's or other high end new stuff, while I rumble around in the 300D. They enjoy making fun of me, I enjoy watching my paycheck go into the bank while they drop 60K on a new car. It's hilarious!

A question if you dont mind... if you remove the ALDA how do you plug the opening where the ALDA mounts..or if not necessary to plug it what measures are taken to ensure grime doesnt go down in that area ?
and secondly, what affect ( positive or negative ) to the fuel mileage is expected once the ALDA is removed ? thankyou |

You don't have to plug the opening. Spring force holds the plunger against the opening effectively sealing the mounting position. Check occasionally that there isn't an oil leak. You'll likely see oil the first time you remove the ALDA. That's from the ALDA pushing down the plunger. I used a small dose cup over the fitting for a few weeks. You might need a new one every oil change.
One use for the small washers that come with oil filter kits is to set one or two between the IP and ALDA so you can keep the ALDA in place without messing with the ALDA's factory setting yet having the effect of partially to fully disabling the ALDA. You also won't misplace the ALDA if you want to restore its function. The effect of removing the ALDA on mpg spurs a "guns don't kill" debate. Your right foot decides what happens to mpg. If maximizing mpg is the objective, the ALDA only helps. Some people like to punch it once in a while or at least be able to. Sixto 87 300D |

Thanks Sixto - much appreciated - I will try the removal of the ALDA failing all else - I began a new thread on the power loss issue so as to not hijack this thread. by the way what do you mean by a dose cup ? Thanks again sir |
