Whilst out driving today my malfunction indicator came on. The car appears to be driving fine but the light won't go out.
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.
Cluster
warning lights
Whenever this warning light or any
other stays on in the dash it is indicating that the systems control
module (or the system sensor in the case of lights like low oil
pressure, door open indicators etc.) has detected a fault, it then
disables the system (this applies to ABS,TCS, TCM, SRS, TPMS, MIL,
CEL and BCM faults and others) as long as the light is on. You must
now have the dealer hook up a special electronic diagnostic tool and
"scan" the system for the fault code that is stored for the
problem(s)
