What does it look like.
If it's the engine management light u need to get it to a garage. Usually serious. |

Mine came on last night too. I drove past my garage on the way to work this morning so I popped in and they said they would rig it up to their diagnostic machine and check it out. I am still waiting for the phone call. Looking online my light could be anything from a minor condition like a sensor or some grit somewhere to the other end of the scale where the engine is on its last legs !!!!

I checked my manual and all it said was 'take it to your nearest garage'. So I looked online (I have a Kia Sportage) and its my management light. |

Nine time out of ten the problem with a vehicle warning light is with the sensor.

If you want to read the codes yourself, this is a useful bit of kit

Mine was soot on the sensor. Find a nice stretch of open road and floor the accelerator for about 5 seconds. It blows the soot away.

Soot would be more likely on a diesel powered car, not sure what the OP has.
That said, I guess other dirt etc can build up on any of them. |

On diesel cars it might mean that the fuel injectors need a bit of jet cleaner putting through or you might need the air filter changing. There again it might not. The best way to cure it is by putting a piece of black tape over the light.

Sensors vary in cost and difficulty of replacement. And of course the fault could be transient. |

I took my car to the garage the other day and they said that it was my turbo boost valve. I have no idea how much it will cost to replace as it needs to go to a main dealer.

Youtube is your friend - someone, somewhere, will have made a video about what this is and how to fix it.

It's just an advisory warning and can often be ignored. You usually find in goes away after switching the engine on and off three or four times, although not by just sitting there and doing it when you're stationary. My Citroen used to do it quite often and the usual diagnostic code points to the air flow sensor, although this is often a complete red herring.
On diesel cars it might mean that the fuel injectors need a bit of jet cleaner putting through or you might need the air filter changing. There again it might not. The best way to cure it is by putting a piece of black tape over the light. ![]() On the Citroen you need to use the correct diagnostic tool which is called Lexia...this will be able to check every sensor and injector/fuel pump, fuel flow, etc, etc. I use Lexia and it's sister tool PP2000 for Peugeots. To test your air flow meter disconnect the electrical connection that goes to it...if there is no difference then the air flow meter (sensor) is fine....if the engine runs badly then it's faulty. |

There could be any of hundreds of reasons why the light has come on...sometimes the light comes on because the computer has detected a fluctuation in voltage and switched the warning light on....not a big deal but a warning non the less ...a simple code read is required and more importantly a code clearing operation as the code will be stored in the computer and may not clear until manually switched off...sometimes a simple fault that has corrected itself will result in the light switching itself off after several cycles of switching on and off of the engine, but the code will still be stored in the computer.
The best course of action is to plug in a code reader and see what the ECU thinks the fault is. |

could be anything from minor fault to the engine is about to give out. No-one here is going to be able to diagnose it so get it to the garage
