Ben-san Posted September 8, 2005 Share Posted September 8, 2005 As I was shopping around in Heckler's thread about designing an LED warning system for dash conversions, ( ), it got me thinking about my strange fuel warning light. It tends to come one at different levels of emptiness. Once, it came on when the guage was reading at 1/4 full At what level does everyone's warning light come on? Thanks in advance!

Pete Posted September 8, 2005 Share Posted September 8, 2005 Seems to be more consistant on the NA than on my TT. The TT is how you describe. Link to comment Share on other sites More sharing options...
irfan_habib Posted September 8, 2005 Share Posted September 8, 2005 My fuel light has never switched on. It would be interesting to know what level it comes on at. Link to comment Share on other sites More sharing options...
Steve W Posted September 8, 2005 Share Posted September 8, 2005 Both my old TT and my new N/A do EXACTLY as you described ! Sometimes come on ~1/8th. sometimes almost on bottom mark !! It will sometimes come on quite steady and then go out 3-4 mins later and not come back on for ~5-10 miles ?!?!? Definitely seems "DETACHED" from the NEEDLE as-it-were ? FatS.

Ewen Posted September 8, 2005 Share Posted September 8, 2005 Mine comes on about 55 litres used from full, which seems to say there is a big reserve left but Ive never trusted it....yes it has a mind of its own, but usually starts to come on under braking / acceleration / fast corners, then go off for a while at steady speeds....the fuel level sender may be in a corner / one end of the tank which would explain surge readings at low levels.....basically a long-winded way of saying the Supra fuel gauge is crapo Link to comment Share on other sites More sharing options...
Dale B Posted September 8, 2005 Share Posted September 8, 2005 Mine only ever come on when the needle is just above empty Link to comment Share on other sites More sharing options...
Paul -C- Posted September 8, 2005 Share Posted September 8, 2005 If you are driving with a heavy right foot it will come on earlier, since you are using up the petrol faster. Link to comment Share on other sites More sharing options...
Kev.O Posted September 8, 2005 Share Posted September 8, 2005 Mine does the same and I never know how far I can go. I read the owner's manual last night but it doesn't mention how many litres are left once the light comes on. Link to comment Share on other sites More sharing options...
Ben-san Posted September 9, 2005 Author Share Posted September 9, 2005 Cheers lads, glad I'm not on my own with this. I suppose it's not worth the worry, I was more worried that the warning light was more correct than the guage. Let's just hope it's the other way round Link to comment Share on other sites More sharing options...
chilli Posted September 9, 2005 Share Posted September 9, 2005 Mine only ever come on when the needle is just above empty Mine seems to operate like this too. Whenever I see it I panic if I don't know the wearabouts of a local garage lol Best not to let it get that low, I tend to fill up when it gets down near 1/4 full now. I've noticed the gauge is seriously non-linear though! PS: I read somewhere it "should" come on when there is only 10l left in the tank Link to comment Share on other sites More sharing options...
Kev.O Posted November 9, 2005 Share Posted November 9, 2005 Sorry to drag this back up but was coasting to the petrol station the other day after driving 20 miles with the light on praying it wouldn't run out. I managed to get 73.99 litres into the tank, but still don't know how much fuel is supposed to be left in the tank when the light first comes on. Can anyone shed any light on this subject!

ArghJae Posted November 9, 2005 Share Posted November 9, 2005 I find that too, when I'm driving heavy the fuel light comes on earlier but when I go back to cruising it turns off. Think it depends on how it's driven at the time. Link to comment Share on other sites More sharing options...
