Here's a 240D passing another vehicle on the Autobahn. It is possible!

What's 130kph work out to? 60?70?

As quiet as that car is running at that speed, it's certainly a manual trans, probably a 5 speed no less...

100 kph is 60 mph.

I absolutely hate climbing hills in my 190D. It's scary.

bout 80.

Not sure how a 240 stacks up against a 1963 190dc, but in general you just have to commit the engine to full output most of the time. Downhill excess speed is just an investment in the next uphill. There is no mentum like mo mentum. On a flat that car would do 65-70, flat out, after about 5 minutes of acceleration, with a tailwind.

Marginal power is kind of fun because it really makes you aware of subtle changes in road grade that would go unnoticed in a more powerful car, like a 617. And you really feel like you are getting your money's worth with the pedal on the floor all the time. I mean, who gets to drive a car like that in normal traffic? Fast cars are such a waste on public roads.

You would notice the subtle changes in a 617/60x if you ran flat out too...

I am.planning to test that theory soon.

Still cleaning up my recently rescued automatic 240D. At the moment, I may as well install a light switch in place of the pedal...

I'll go over the throttle linkages eventually... it's definitely on the list.

It does not cost anything to address the throttle linkages.. unless you have a broken piece like that rubber connector... but many have been pleasantly surprised at how much difference having them correct made... with so little power from the factory.. you really don't want to cede any to a simple mechanical arrangement which does not allow you to apply full ' throttle'.

One of the first things I did when addressing the power of my 190D was to make sure I had absolute maximum pedal travel and could get 100% full rack travel. I recorded a video from my phone of the IP linkage. First I pushed it all the way to the full load stop with my hand, then I went in and pushed the pedal to the floor and watched the video to verify the pedal moved the linkage to full load.

Between linkage, fuel filters and tank screen, lift pump and overflow valve, injectors, injection timing and cam timing you can get most of its original power back.

Nothing broken that I can see, but it's all pretty sloppy in there. Haven't found (read - haven't looked for) a good reference for the correct lengths and travel yet. On the list...

Video sounds like a good idea, though I can't really see much from the drivers seat. Maybe if I didn't raise the hood all the way to the service position every time, I'd have a better view. I already swapped all the filters, but I still need to check the tank screen... also on the list...

DO take the time to look in the FSM for the pull and push rod lengths ~ they're usually way off .

Once they're correct your shifting will improve greatly .

I just did all this on my 349,XXX mile 1982 240D with only 200 # compression in # 1 cylinder , wow what an improvement !~ it's very zippy and doesn't need full throttle almost never to go as fast as it's going to go ~ this is how you know you've got it right : they're not very speedy but should get there easily on the flat .

I was able to bury the speedo needle , a pleasant surprise , I need to find my Garmin and see what's the actual top speed now , it used to run out of steam @ 83 MPH , dead flat , no wind , etc.

You can reverse the supply and return lines in the engine bay temporarily with a full tank of fuel. This draws fuel from the return and returns it through the strainer. The hope is that it blows some of the junk off the strainer. I swapped mine on a full tank, drove it down to a quarter twice and the switched them back.

because one accident killing folks and destroying vehicles is carbon neutral, right? lol

To the OP- yes full throttle is needed to pass. That's normal.

That's one of the very worst things you can do ~

Any crud that comes loose , will be sucked right into the fuel injection system .
