Intermitent Buzzer And Warning Lights

[simonplatt]

c3 desire 1.4 2004.

a while ago i had the handbrake warning light along with the associated buzzer sound briefly.

i  looked at the switch and glued a cap onto it to make sure that it went off, but the problem persisted.

then i started to get the warning buzzer with the ALB light, so figured the sensers needed cleaning, did that twice (as i rushed it the first time) but to no avail.

then i had the warning buzzer on its own, low fuel, but the fuel wasn't low.

now i get one or other light, with buzzer or ,buzzer on it's own,  or both at the same time,

now the buzzer is common to all three, but has anyone had a similar problem or any idea how to cure? i have tried disconnecting the battery and reset process, and there are no faults showing on the meter.

You could check the battery voltage, our C3 would give 3 beeps on starting when it was low.

 

On the fuel gauge, is it showing more than 1 bar when it thinks the fuel level is low ?

 

By ALB do you mean the brake ABS light ? If this is on then you would need a code reader that does ABS to check what it thinks the fault is. However, if you have a voltmeter, you could unplug each sensor and check the resistance across each sensor and if one is different then it may be faulty. Also check the wiring to each sensor.

 

The handbrake light is also shared by the brake fluid level sensor so you should also check the level is not low.

i think that you could be right there paul, i think that the battery is not at its best although it has not let me down, and it is always 3 beeps.

 

fuel guage = 1/2 tank

 

yes ABS. ( typo incurred by the mental strain of changing to capitals. :rolleyes: )

 

brake fluid is not low.

 

i will get out the multi meter. thanks.
