recently looking for oil leaks on my MB 300D w123 I realized that under the air filter housing around the hose that comes from the motor head, there is a lot of oil as well as inside of it at its bottom. Where does it come from?

Mercedes W124: intermitin hard start and running problem

Mon, 30 Jun 2025 02:41:54 -0700

my '92 300E i6 has started to act up . Hard start and acts like the timing is retarded, then starts and runs fine. Sometimes the throttle needs a soft touch or it stalls. My guess is a sensor but I don't know where to hunt for one..

replaced both water temp sending units on the head. Car starts and runs fine till it gets to operating temp, then it stalls and backfires. It is not running hot, water level is fine, lower and upper hoes are hot so it isn't a sticky thermostat. I'm stumped.

Mercedes W123: Shout out to the contributors!

Tue, 27 Aug 2019 14:57:26 -0700

I've had my W123 for almost 2 years and still find some things on this car confusing. And to think I'm a Master Tech for GM. Sad, I know, but I just wanted to thank all of the contributors to this thread. I've been able to make nearly all of my repairs and restorations through this section of ifixit. There's still a few things I need to figure out, and will probably be asking questions, so I'd like this opportunity to give even more thanks in advance!

Mercedes W123: W123 300 coupe rear window

Tue, 05 Sep 2017 17:41:34 -0700

Doing online research about rear window problems ( not rolling all that way down) I've found that is a very common problem, however, answers never seem to be accurate on how to approach the problem, some guiding towards regulators, others to switches etc .

My own problem is that window stop rolling down , when is 3/4 open and 1/4 left to be totally .

Can you please share some data base on your experience at this matter ?

Thanks you very much .

Mercedes-Benz: radiator hose connection nipple broken off.

Thu, 09 Oct 2025 06:57:13 -0700

On the top of the radiator is a small plastic connection of which a hose connecting the radiator with the coolant expansion tank. this hose is small and is connected above a larger hose to a small plastic nipple the hose is connected to and clamped on. the neck of the nipple broke off, leaving a hole where coolant pours out. Is this a separate part or can it be fixed?

Mercedes W123: Rough idle with clicking sound

Sat, 26 Jul 2025 17:51:29 -0700

Hi,

I just bought a restored Euro spec 1983 Mercedes 300D W123 that was running beautifully until last week, when I filled it up with Propel Diesel HPR, a renewable diesel that is supposed to be compatible with all diesel engines (and is marked as Diesel #2 that meets ASTM D975 specifications: http://www.dieselhpr.com/ ). Then I drove for four hours to Las Vegas from Los Angeles without any issues. It ran well for that evening after driving to a restaurant, parking, then starting again and back the hotel, where I had to park it outside on a cold and rainy night overnight with about a quarter tank left.

The next morning, I had a crazy cold start and the engine was shaking and wobbling a lot, along with the car as a result, even while I was driving slowly and definitely at idle. It eventually evened out, or so I thought. I figured it might be the Diesel HPR, so I filled it up later that day with regular Diesel #2 but the issues didn't go away the four days I was there.

I drove back to LA four days later, experiencing no issues on the highway, where it sounded and ran well. I ran the tank down until the fuel indicator went on, and then, in an effort to rule out Diesel HPR as the culprit (since it's supposed to be better for the environment), I filled it up with Diesel HPR again, thinking maybe it was just the cold in Las Vegas that caused the issues.

This week in LA, the temperature hasn't been as cold at night, even though I park it in a garage, and the issue seems to be worse. The wobbling isn't so bad once I get going, but it's there at the start and sometimes when I stop for a light. Meanwhile, the clicking sound is pretty constant, and sounds as though it's coming from the bottom of the car, though it sometimes quiets down at higher speeds and randomly at some lights. Since it was literally conking out during the cold start once I started reversing or driving slowly, I am now cold starting with the ignition lever turned up, and that hasn't really made much of a difference (just makes the clicking sound faster). Also, white smoke comes out of the exhaust during this initial starting period, and a few minutes after getting on the road, though it seems to disappear later. I've been waiting for the glow plug lights to go off, as indicated in the manual. (Weirdly, the glow plug light went on again a couple of times after the car started during the rough cold start/idle.)

At any rate, at this point, I'm not even sure if it's the Diesel HPR or something else (the cold, driving to LV) that created the issue, but am wondering if anyone has any ideas as to what the issue could be. Or does anyone have any experience with Diesel HPR and older diesel engines? I'm hoping this is an easy fix, since I just bought the car.

I'm going to take it in to get looked at, but am wondering if this is serious and urgent or if I should try it one more time with regular diesel to see if that clears up the issue. I definitely don't want to make the car worse if driving it more to troubleshoot does that.

In a perfect world, I'd like to be able to use Diesel HPR as it is better for the environment, so I'm wondering if it is even the culprit here. Thanks in advance for any advice or insight.
