Low Fuel Warning Light Mystery

1658 Views 14 Replies 4 Participants Last post by  StrichAcht 240D
The low fuel warning light in my '85 300DT sometimes glows in the morning when I first start the car even with plenty of fuel in the tank. It usually goes out after it starts. Anyone have any ideas about this mystery?

Fuel Light Glow

Mine also glows on start but also do the battery and another light. I think its normal and as to why I'd completely guess for a preliminary check of circuits and components.
water in the water/fuel separator?

It doesn't cause me any problems. It has caught my attention that, possibly, something may need checking.
Do you know if this is a "water in the water/fuel separator" warning if there is such a thing in a Mercedes? I am still getting aquainted with this automobile. There are things that I have assumed about this car that have turned out to be the contrary.

No - none of the diesel mercedes come with water separators. There is a possiblity that someone could have put one on the car before you, but that wouldn't be reflected in any lights on the car.

Well, there goes another assumption about M-B out the window. A diesel without a water separator is a problem waiting to happen. Even my simple little Datsun diesel pick up had a water separator.
There are six fuel filters between the tank and the injection pump. Hopefully, unless you get some really lousy fuel, you will not have a problem.[xx(]

As EdMclass pointed out, the reason why there is no water separator is because one of the SEVERAL fuel filters will catch the water on it's way to the engine.

I have never seen an MB diesel that had problems due to water contamination. Niether has my MB Mechanic.

I don't mean to attack you, but it is apparent that you keep pointing out what appear to be to you "little errors" made by the MB factory. However, the truth is that there is a reason for everything that is on that car. It is a well known fact that these cars are probably the most over-engineered cars on the road. We could argue this all day, but the fact is that more than one of these cars (actualy several) have completed over 1 million miles. Many right here in the USA have completed over 500,000. The fact that there are more of these cars on the road than almost any other from the time period speaks for itself.

Sorry for the rant, but I had to get that off my chest.

Never a fuel problem, although I did pump 5 gallons of kerosene into my '83 240 D before I realized my error! Silled up the other 10 gallons with #2 Diesel. The average US Diesel Price is $1.66 today, the lowest price since February 10th! A 9 cent drop. in a week!

Better than me getting a black eye. My apologies for pointing out only negatives, I tend to get on a roll without realizing I've p*ssed someone off. I'm glad you've put me in my place. I don't want to make enemies with anyone, my apologies to anyone else I may have p*ssed off.
I'm quite happy with my 300D. There are many good things about this car. I have found it, so far, very easy to work on. I'm very glad that there is a forum dedicated to Mercedes automobiles, I've received a lot of good advice from a lot of good members out there. I look forward to putting many, many miles on this car with the advice from the BenzWorld forum members.

Thank you for responding politely to my semi-attack! Appology definatley accepted! I am sorry I didn't mean it to come out so harshly - I guess I was kind of in the mood to pick a fight [:p]. I would like to appologize as well for snapping like that. Thank you for being understanding - most people just go right back at someone (which is normal given the situation). I am not looking to make enemies, either - I just get a bit wound up sometimes. Plus it's easier to do it over the computer than in real life.

Anyways, glad to hear your happy with the car. Again I am sorry for the outburst!

No problem, apology accepted as well. I needed the "punch in the nose". How do you add the list of cars that you own at the bottom of your posts?

In the top right of your screen, there should be four "buttons" together in dark grey/black. Click on the one that says "My BenzWorld".

When the new page comes up, go to Edit profile (under Member profile). When that page loads, go to where it says "Signature" - type what you want to appear in that box.

The Benz is at the top of the list just as it should be.
