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.

Take your vehicle to a parts store and have them run a diagnostic on it. It will tell you what code came up and that will give you a good start.

If it is an error produced by the engine control system, you should be able to clear it using an OBD II reader. OBD=on board diagnostics. You have to find the plug for the unit, but just plug it in and the machine will read it. I usually borrow one from the local car parts store--give an ID and they will let you temporarily borrow it. Make sure you read the error code as well. There may be some interesting info about what produced the error message. Good luck.

most of the time the disc is bad but when the disc goes bad its the navi unit that causes that to go bad so if you replace just disc will need another one soon after recommend replacing unit or ship to repair facilty for repairs
