I was glorying in the fact that my Chimaera 500 was showing 270 miles on the trip meter and the fuel gauge was still showing quarter full - then the car stopped! Just by a fuel station fortunately. Anyone had the same problem? Is there a cure for sticking gauges? It's only happened once, but I am not likely to be that lucky again. Is Gauge or sender unit responsible?

I have had near misses, just wish I could get 270 miles out of it though ! I find that if you have switched off the car when it still merrily told you you had quarter of a tank, that when you come back and switch on, you can sometimes be just off empty. I have just put this down to presure (or something) in the tank when the engine/pump is on causing a false reading. I was told to think about filling up whenever I get to quarter full - not a bad rule if you are not confident on the level. In reallity, I tend to work on a combination of the level and the milage. anything above 200 and I start thinking seriously about filling up again.

same happened to me, taking it easy coming down the A1 I was impressed with the apparent range when it sputtered to a halt with 300 on the clock, doh!! so I top up at 1/4 tank now but I have noticed that even when filled to the brim the gauge wont read full

When I had a Chim I had the same problem. Here's how to fix it. My fuel gauge showed empty when there were about 8 gallons in the tank. If the tank was full, it showed 3/4 only. Here is my solution, but be aware that it is an awkward and dangerous procedure: 1. Open the boot. Loosen the trim on the right upper side of the tank. Unscrew the fuel sender and take it out. Close the open hole with something! Re-connect the cables and turn the ignition on. Move the white float up and down and look at the fuel gauge. 2. If the needle goes from empty to full then you have to adjust the sender by bending the wire up or down. Hold the sender outside the tank in the same level that it is buit in and arrange the wire so that the float is in its lowest position about 2-3 inches above the lower edge of the tank. You must be sure that you only bend it up or down, not in another direction, to avoid the float rubbing on the front ofr back wall of the tank. In most cases that's it and you will have enough petrol for 20 miles when the warning light goes on. 3. If the needle does not reach "empty" or "full" by this procedure, then it's a little bit tricky. You must remove the fuel gauge from the dashboard and open it. Remove the black or chrome ring and remove the screws at the back. Inside, the pointer is connected to a small coil, which moves in a cage. You can turn this cage to adjust the position of the pointer on the scale. Turn it so that the needle reaches "zero" if the float is completely down and "full" if it is in the highest position. Secure the position of the cage with a drop of glue and repeat No. 2. It only take 1hr to do + time removing the dash (2hr+). It worth doing for the peace of mind. I hope this helps Duncan

The sensor for warning light in the fuel gauge is in the gauge itself. I think you can change the point it comes on but I can't remember, I sold my Chim in November. Try speedy cables in london. They do gauge calibration etc and may be able to help.

Where is the actual light? I've never seen one come on in my 500... I'd be fabulously happy to know it has a warning light, and even more extatic to know roughly how much fuel remains when it does so. Ta...

I've had a look for this low petrol warning light and I simply cannot find it. Any clues?

I spoke to Mole Valley - there is no warning light for low fuel. Apparently, there used to be a light but it was so unreliable they gave up putting it in. Guess we have to rely on the trip meter then!

Hi, The warning light is built into the gauge. Look for a small orange light at the 1/4 full mark. I had a 93 k reg Chim with a fuel light but no trip counter. so maybe they swapped at some point? look at TMS Gear website to see if they do a replacement.

I seem to have a different problem with the fuel gauge. I fill up and the gauge is off to the right somewhere - well past the full label.
Once I have motored abou 100 mls the gauge hits full and then takes about another 80 mls or so to get to half full.
Is there any way to re-calibrate the gauge/sender or am I stuck with working out how much fuel I have by the mileage travelled - with no trip meter ?

If anyone needs a fuel tank sender (the float device previously mentioned), I have one that I bought but didn't need, because it turned out the guage was faulty. E-mail me and I'll send it off for a piffling sum!!

I had the same fuel gauge problem as "Bob the Planner" on my '97 Chimaera 4.0HC. It turned out to be an incorrect connection behind the dashboard (happened when I had a new dashboard fascia fitted)

Thanks Taffone. I need to get the dash off to fix a couple of dud bulbs - although it seems a right pig from other threads. I will have a look at the back of the gauge.
