Fuel warning light.

When you switch on the ignition does it come on with all the other lights before you start the engine, cause mine doesnt!

A pain in the bum this as i have done 2 fill ups and only managed to get in 42l and 47l. Both times the gauge only went up to the 3/4 mark. The light didnt come on either, but i suppose it woudnt if it still had about 30l in the tank!!

Thanks
 
Nope. I always find it a leap of faith the first time I try to get it to come on in a 944 "will it come on or is it broken and I'll just run out?"

It has worked in all of mine so far though, albeit the gauge is pretty low before it comes on.
 
In almost three years of 944s I didn't even realise they had a low fuel warning light.

I wouldn't have thought it is the best idea to allow the tank to get too low, if you can avoid it, all manner of crud can build up after 10+ years.
 
I've never yet run out and I've pushed it to 50 miles from the light flickering on, so waiting for it to light up still means a fair bit of fuel in the tank. I rarely bother to even consider a fill until the light is on.
 
Cheers, just begining to get abit edgy as the guage is well low. But i too have titanium canolies [:D]
I want to try and run as late as possible to see if i can get atleast 70l in the tank. Then atleast i wll know its the fuel gauge that is dodgy.

Thanks.
 
On both of ours the light doesn't come on until the needle goes through the red section and is about to come out the other side, I always fill up when the light comes on and generally get another 60 litres in the S2 and 70 in the Turbo. Once manged to do 40 motorway miles after the S2 light came on but I was a bit panicky [:eek:]

..........oh and half a lap of the Nurburgring, which was a bit nervy (I had to get that plug in [:)])

Ok time to play devils advocate, because this is a discussion I often have with my workmates, and none of us can agree [&:]

Why do people worry about the crud at the bottom of the tank, because the exit pipe from the tank does not take fuel from the top, it takes it from the bottom where all this crud is suppose to be anyway.

Plus if some crud did get sucked out it shoud get stuck in the fuel filter, which we all replace every two years anyway.

I await your considered responses [:D]
 
Absolutely.

I once siezed a pump by running out of fuel, however - in an Ashtray GTE, not a 944.
 
Got caught out last week when the fuel light was on but the gauge read just under 1/4 full.

And I ran out - on the M25!

Luckily just made it to the next juction - Phew.

It all comes down to the crud to fuel ratio. The more fuel in the tank, the more volume you have to suspend crud. When you get down to very little fuel, the same amount of crud will make a silty mire which will clog if sucked into the filter.



I just made all of the above up, off the cuff, but it does seem to make some level of sense to me. [8|]
 
I believe the "don't run low" advice is based not on the amount of crud in the tank, but on the basis that if there is less fuel then more of the inside of the tank is exposed to the air which will lead to more rust than if the tank was more full on average.

The rust is then the crud.

More made up stuff, but I wonder if the same advice is given to owners of cars with plastic tanks ?
 
Ignoring the crud issue for a bit once the light comes on (oval dash cars sorry don't know about the earlier dash) it illuminates a new section below the red - does anyone know how far down this section can you go without running out?

Also with filling the turbo I find that when the pump cuts out if you wait a few secs or just add fuel slowly or even rock the car slightly some air will escape and more fuel can be added £2 or £3 then the gauge reads full.

Crud I'm with Paul on the outlet at the bottom of the tank and 937C on not leaving the tank empty especially if the car is not used for periods in the winter.

There is the 'in tank' filter as well so I guess if you had lots of large crud and hardly any fuel you could block this and stop prematurely.

I tried but i just couldnt take the pressure, the needle was almost pointing vertically down and still no light. The car started missing slightly i.e. running out of fuel so i had to fill up. I got 69 l in the tank so does tha mean i still had 11l to go? Did i just miss out on iluminating that illusive light.

How many miles would "2 years" correspond to ?
I change the fuel filter every 12,000 miles, which means every year.

That was me just being a pedant as when I was looking at cars there were very few that had any evidence of this scheduled job being done, or the gearbox oil either [:eek:]

I think the service book says 2 years or 24,000 miles whichever is sooner (but I don't have it in front of me just now)

I am guessing that maybe your bulb has gone then. It's an orange square that illuminates and if you can imagine it as a continuation of the red mark. 69 litres seems low though, I put in 60 the other day and my needle was above the Red

Who will be the first anorak to post a picture of their Orange light for Slim? [:-]
