Another day, another try.
I tried to start it in the morning, with a full battery and everything. Didn't work. Despite letting it glow for a while.
Ok, i thought to myself. Maybe it just needs some more cranking, just load up the battery and try again in 2 hours...
During those to hours my cousin called if she could come by to see the 200D run. "uuuhhmmm yeah. It doesnt run. But you can stop by and we can pull-start it."
1 hour later - 1pm my cousin arrives, and we hook the 200D up to the W124. After 200 meters of pulling it starts, ok let it settle in a bit before we stop and i drive it home by itself I think to myself.
That's when the engine starts to go TACKATACKATACKATACKATACKA-BUMM.
F**K.
I wildly honk at my cousin and gesture to stop, while forgetting to shut the engine down. Smoke pours out of the engine compartment. When we are at a standstill, i shut the engine down too.
A quick look into the engine compartment reviels the problem: Cylinder number two had blown out his glowplug

...
Keep in mind, the engine kept running on 3 cylinders until i shut it off, no problem whatsoever. Well, apart from the huge cloud of smoke and the weird noise and... but im getting distracted here.
So i tell my cousin to drive to the next village where we can turn round.
Off we go, everythings fine, until on the last turn after which the road goes back to my home, we cut the corner too tightly, and the rope snaps
You're thinking now, that this might not be my day? Continue reading.
So now i get a ****storm from somebody who lives in the neighbourhood, of what in hell am I thinking, what if an accident had happened, and how do i plan to get that piece of ***** home? Calm down, i live 2 km down the road nothing will happen, we won't do it again. So he drives off, and we are right in business again, just reattach the cars, and then head home.
Just as we're about to do that, another man comes by foot with his family. He seems to be nice, at first he semms to smile at this whole mess I'm in. I greet him, and he asks me what we did there. So i tell him the story minus the part where the glowplug shot out of the engine block. He then asks me if I am aware of how illegal what I'm doing is. I tell him no, (Hell yes I am aware of it, i just didnt think it would go THAT wrong) He then proceeds to tell me why exactly it is illegal, and then he casually throws in there that he's
A EFFING COP My brain goes all like

WTF...
Luckily he let us go without any form of punishment, wich i'm very grateful for and i told him that.
But part of the "no punishment" deal was to not pull it back home like this, even if it was just 2 km.
So i call somebody I know who has access to a trailer and ask him if he can tow it back. Thankfully he agreed, (I'm also very grateful for that, since I only know him casually, mostly because he is into old benzes too

)
So there we are. Car back in the driveway, bit more broken than before.
And i learned that a lot can go wrong, but if you're lucky about the people you encounter and know, it won't be so bad
Oh and here's a pic of the glowplug:
