The engine is an oily mess. What is the best way to clean these? Degreaser and then a car wash?
Hopefully you did not ruin the transmission towing it like that. MB's are not supposed to be towed with the drive wheels on the ground.

My TD did great towing. What a car. Had to go up a huge hill too and it took it just fine in 2nd. I was gonna use the suburban but i wanted to see what it could do.

I hope not too. We talked about disconnecting drive shaft but didnt cause the short drive. I only went 10 miles and kept it at or under 30. The owners manual says its ok up to 30 miles with all wheels on the ground and under 30mph. However it does recommend a flat bed.

I really hope its ok cause that thing started right up today. Had some bad red fuel in it that smelled like turpentine. I plumbed in a can and it fired up after one glow. Once in got warm it idled good. Oil pressure and temp good. Everything works pretty good except the back headrests don't come up. Didnt test ac yet cause i swiped the Klima relay for the wagon last week.
Need to drain fuel in tank and go for a test drive.

I tried the windows and all 4 went down and then heard cracking and the back two got stuck. The front ones are having issues too but went up. Guessing after 2 years of sitting the slides need some grease. Too bad. Had i known i could have taken off door panels and lubed em. Hopefully its an easy fix.

I'll be happy to take that lower cladding off of your hands.

Ok. So trying to drive the black 93 W124 300D 2.5 T. It wont go anywhere. I think it is alda or computer issues rather than tranny but i do not know. Here is the scoop -- it starts right up but will not rev up initially. When you push pedal to floor when its cold it cuts out a bit. After it warms a bit it will rev up to 3 and 4000 rpms. But when i put it in gear, it won't rev up at all. It will move slowly on level ground forward and backward but since it can't rev up it wont go up a small hill. In park it will rev up. .

I put manual vacuum on alda and it held vaccuum. It did not increase power or change anything. I'm trying to take off the alda but that intake is in the way. Is removing the alda the next best step? Do you all remove the intake to remove alda?

Thanks for any help. Since it shifts good from park to R to N to D and goes forward and back im thinking its not a trans issue. Its weird though, why would it not rev up in gear but rev up in park? The extra load of trying to turn wheels maybe ? Hmm. i just don't know. That little electric switch on valve cover that is hit when it goes to WOT -- what does that do? You know the one that is black and there is a black rubber bumper thing on throttle lever that pushes in the switch when the throttle lever is almost all the way down. will post a pic in a minute.

Thanks

Oh yeah, i had this slow until warmup and barely go anwhere on an 85 300DT. It was not this bad but until warm it would barely go and then if you had to go up a hill or floor it it just was really slow even after warm up. I removed the alda and it flew. I'm hoping that is what it is here but the problem is so extreme maybe it is something else.

I'd start with the fuel filter, then fuel strainer, ... try fueling it directly with a container under the hood.

+1 with what Jeff said. Even with a dead turbo the 2.5 will rev and be able to get out of its own way. I would only mess with the ald as a last resort. It wouldn't hurt to pull the hard vac lines and make sure they are clear.

Wohhoo. It was the alda. Runs like a 2.5T now. Shifts perfect. I forgot to mention i was fueling it from a jug under the hood already and fuel filter looked newish. Judging by how fast the return fuel was coming -- like 1 pint a minute -- i figured there was no fuel restriction.

This was an after market alda i think. It had a little nipple that the vacuum line plugged into and it hung down right in the way of getting your wrench on it. and it would not spin to get out of my way. I had cruise control off and the washer bottle out. I broke nipple off. still could not get a wrench on that skinny alda nut. The wrench was bigger than the nut. I needed a skinny spanner like 1/8th inch thick to get on it. Otherwise it was bumping into the big nut.

Well there's more than one way to get the alda off. Finally, I chiseled it off. I'll post pics . A screwdriver placed at bottom ring on alda , right above bottom ring, aiming slightly down, BAMM! . punches a whole right in it. Do that all the way around like opening a can of soup with a swiss army knife. You can spin alda with big pair of channel locks. That top pot can part just spins on the bottom base that has the vacuum connection.

Highly recommend this method if you don't want your alda and cant get it off the right way. Thanks for help. I can't believe the alda completely disabled the car like this. Anyone ever had one so bad before?

If the diaphragm is badly ruptured, the boost pressure will bleed through, never allowing boost enrichment. Still, should allow reasonable power, puzzles me why it wouldn't.

IMO the best test if one suspects an ALDA is to apply 15psi to the vacuum/pressure line and see if it can hold pressure. If not, especially if you can't even pressurize it, it's sapping power.

Yeah. Good tip on testing alda. I'll try that next time. It was weird to me too. This car would go nowhere with this alda on. It could not even go up the tiny hill outside my driveway, moved like a snail on level ground. One thing i realized was the Klima relay was out. But same part on my 87 TDT and it never missed that thing so i don't think that was it.

Now that i think about it, it seems i read something about a computer for the fuel injection -- that thing over there by the Klima relay. I wonder if that could have been it? What does that thing do? I should have tested that first. But, alas the wife had the other car at work and it was gonna be my last nice day to work on it. Rained all day today.

Here are pics of the alda and the fuel . The red bottle is what came out of car and the other is fresh D2 from shell.
