SOURCE: Lacetti Chevrolet. Malfunction Indicator light is on.
It may be the same problem as my 56 plate Lacetti. The yellow malfunction light came on two weeks ago and two days ago, both times shortly after filling up with petrol to the brim, and I suspect it is the petrol sensor as I only clicked the petrol cap once after fitting it back - the handbook says click it several times. The yellow light also came on yesterday after taking the car a short journey so it is likely that the sensor is still picking up a small escape of petrol, but the car has been fine today with no light appearing now that the fuel level has dropped a bit. Like you, I have not noticed any drop in power with the light on.

If your car is still under warranty you need to take it to the dealer for repairs , if you tamper with any thing you will void the warranty , as long as the repairs are covered you don't pay

SOURCE: 2004 Chevrolet Aveo Brake lights not working
A couple of days ago my brake lights on my 2004 Chevy Aveo wouldn't work, so I attempted to remove the lamp covers to check the bulbs. Also, before this my shifter would get stuck in park and could only be released by pressing the unlock gadget next to the shifter. Back to the brakes...Well, you open the trunk and remove the two screws just like the manual said, but it was very hard to pull off. There's 2 prongs holding the other half of the light on. The lamp will come loose by prying it (very hard). You think the cover will break, but it'll come loose. The bulbs were all OK.
After much frustration and internet info, the STOP LAMP SWITCH, GM#96436331 ($9.30 at Chevy dealer), which is located under the dash and has contact with the brake pedal, was defective. Once replaced, both my brake lights AND SHIFTING problems were cured. So if the brake lights suddenly don't work or you have problems getting the vehicle out of park, check the switch by pushing the prong (end that has contact with brake) of the switch in and out. If it doesn't retract smoothly...that's the PROBLEM. Good Luck.
