1981 Mercedes-Benz W123 240D from North America
I recently purchased a 1981 240D diesel Mercedes, and I have been pleasantly shocked with how much I like this car. I never knew anything about these, but I found a seemingly great car, and at a great price, so I could not pass it up.
It is extremely comfortable, in mint condition, and I like that it is a diesel. But, this is my main problem: I do not know much about diesel engines. I need help! It just started to snow a few days ago, I don't have the car in an area I can plug it in, and now it won't start. I tried to start it just two times, but it is not even turning over. It is about 10 degrees outside. It has never had trouble starting in the past! Yes, I wait for the globe light to turn off before I try to start the engine. It just makes a loud noise... Is it frozen diesel lines? Starter issue because it is so cold? Not plugged in? Anyone have any suggestions or ideas? Thanks!
Would you buy another car from this manufacturer? Don't Know

Diesel fuel starts to turn waxy when the temperature drops. You need to have a tank heater, and sometimes a fuel line or engine bay heater to counteract those waxing tendencies. The engine bay heater is basically an electric blanket for your block. The rest just attach to the tank or the fuel line. You will probably have to wait until things get warm again before you can use the car again, since no current car engine runs really well on paraffin.
Check your oil... the recommended 10w40/10w50 diesel oils for these cars are suitable for year-round use, but they're hard to find. Many people run W123s with 15w40 oil, which isn't good in very cold weather (not a problem for me here in Georgia, but it sure would be wherever you are).
