Remember kids - Coolant temp is not the same as oil temperature. Oil can be still too cold. Maybe you should consider some shield on the grill, so while driving its getting less cold air, and will heat up quicker:)
S212 has a vacuum controlled (by an electric solenoid) radiator fan shutter by default. In addition, the coolant pump is also vacuum controlled, which means that the engine heats up faster to reduce pollution and reach operating temp. No need for modifications. The amount of coolant in these models is quite large and the cabin coolant heater holds a big amount of it. This is why an additional electric coolant pump is used to circulate warm coolant trough the internal radiator, which puts out warm air quite rapidly due to its big capacity.
With the coolant temp slowly increasing, it's essential to not force the engine. The guy's doing a great job in this regard. A regular driving style, or grandma style if you will, is the best for the integrity of the engine till the coolant hits the right temperature. Not to mention that even if the coolant hits the right temp, the rest of the things, like oil, are still not hot. That's why it's said that a diesel should be driven in a regular fashion, and not over revving it to speed up the process like I've heard some say, a long distance (at least 100km) 1,2 times per month to let the DPF regenerate and allow the engine to heat up and start burning away the excess carbon. Short distances and driving through the town is what makes diesel engines age faster because they never really get to heat up the way they're meant to.
Totally agree, and a DPF replacement is not cheap on a Merc. My wife’s friend foolishly bought a Fiat 500 diesel. She was only driving from home to work (4 miles round trip) with the occasional 20 mile round trip. After 2 years of having the car, the DPF needed to be replaced. Diesels are no good for those only doing short commutes. When the yellow eco (DPF) light comes on on your Merc diesel, you should avoid turning off the car until it completes its high temp carbon burn cycle. Constant turning off a Merc diesel before it completes the “burn” will result in poorer fuel economy, and worse, a hefty bill to replace the DPF.
I think the worst cold start I did so far was in morning at -25 and still it was as in the video no issue. But I don’t like it is only if I forgot diesel heater or battery out of charge.
This era mercedes V6 engines are beasts. I drive a C300 petrol 3.0L V6 in the finnish winter and there's no problem starting the engine at -20 after standing the whole night
@@MB212G my chrysler 300c crd with the same engine has no glow plugs working and at - 4 it took about 15 seconds of cranking to start. Just go to show how important glow plugs are.
You should get the amg menu instaled. Got it done on my C204. You can see the oil temp. too which is helpful. And it always takes longer to get to optimal temperature so be careful. If your coolant reaches it, it doesnt mean you can go hard on the car
I also got the amg menu just for the oil temprature. When watertemperatur hits 90 degree celsius oil is about 60 to 70 depending on the temperature outside
@@STFDVC1 yes, when the coolant hits optimal temperature, my oil is around 65-70c. And optimal temperatures is above 80c i think. So u should go easy because the engine oil is still warming up + if u have a automatic trans. the oil there has to reach optimal temperature too. Just these little tips can make your car long way longer and better
Hey man, love your videos, they are very nice to watch. As a diesel driver in an environment so harsh, can you give us some advice on how to keep the engine healthy when operating in low temperatures? Thanks, and keep it up with the videos 👍🏻
Thanks! Actually the only thing we kinda do here is always use auxiliary heater or electric engine heater before we start the car, is not good to make cold start to often like I did in this video. Other then that’s is not much to be honest, some like to put some protective against the grille to get engine heat fast and to keep it better.
Coolant temp is not your engine operating temp. The temperature you are looking for is your engine oil temp. It takes quite longer as your coolant temp to be at its operating temperature. Most modern cars won‘t even get you the option to display it.
You reached appropriate operating temperature because you kept it on about 2000rpm. If you would leave transmission on D (without manual mode), rpm will be much lower and the engine will really hard reach operating temperature within 15min. I do not have experience driving on snow, but probably manual mode on snow is much better cause of stability?? Nice videos and brutal car! Keep it up
Have been driving a lot on snow - automatic mode is absolutely fine. Manual mode is fun if you want to feel the car better and do some controlled drifting or slowing the car a bit faster.
@@danpan6420 Mercs have a winter tyre setting (on the newer mercs) and a W setting on the older ones. Both start the car moving in 2nd gear and change the ESP responses.

“Closing the bonnet Lower the bonnet and let it fall from a height of approximately 20 cm. Check that the bonnet has engaged properly. If the bonnet can be raised slightly, it is not properly engaged. Open it again and close it with a little more force.”
@@dragospahontu It depends what kind of ice, if its like mirror it dosent matter what tires you have its going to be slippery, but if normal "icy road" then winter tires keep you in the road. I have 225/55R17 tires and I use 2,7 bar pressure all seasons.
@@dragospahontu In fact you should have little bit more air in winter, because when its getting colder the tire pressure is going down, you lose 0,1 bar / 10°. And if you want your winter tires to work well, you should have the right air pressure in them.
I also have the same car since 3 weeks, i noticed that sometimes it runs stationair at 650rpm and when you drove a little harder it runs at 500rpm. Also when its running at 650rpm it shifts late and at 100kmh its not putting it in 9th gear. When its running at 500rpm it does put it in 9th gear at 90kmh

Your car seems like a wonderful daily runner. My S500 is it's a 2000. I do have a question though. Does it take longer for diesels to get to operating temperature than gasoline? I'm not totally sure but I think they do if I remember correctly?
Yes, that's correct. Diesels take longer to get to operating temperature than gasoline engines. That is why it's better to have gasoline if you often drive short distances :).
Diesels have higher thermal efficiency, around 40%, which means that they convert 40% of fuel into kinetic energy instead of waste heat. On the other side, gasoline is about 25%, efficient, so there is more fuel that goes into waste heat there. That's why diesels have better fuel economy than gasoline engines and take longer to warm up.
It takes about 24 seconds for the glow plug to get red hot. A glow plug indicator normally would extinguish after about 4 seconds and the glow plug in this case will be barely warm.
@@danpan6420 Not true, a modern glow plug takes just a few seconds to get red hot. Cant compare them to, say, a Benz w123 240d glow plug, they take forever to warm up.
@@MB212G i have to say that this diesel warms up very quick. I think if you would test this with a small 4 cylinder diesel like a 2.0TDI from VW it would take like 20 minutes to get the coolant to like 70⁰C

@@MB212G From my experience oil gets warmer way slower than coolant. Not to mention and I don't know for sure if this applies to MB cars, but on VW group cars the temperature gauge for coolant show way different reading on cluster than what is real temperature. Usually the cluster will show 90 degrees even though temperature is only 70 degrees. I actually never drive by coolant temperature. When I start my engine cold I always switch to oil temp. and make sure I drive softly until it's at least 70 degrees.
