Engine light.

Hi again,
Started the car and set off, all of a sudden I noticed that the engine light was on, the yellow one that looks like the engine, anyhow, set off today and it's still on. I notice that in the drivers book it says " warning light comes on. exhaust emission values have deteriorated. have the car checked as soon as possible. " What exactly is the problem, is it the exhaust or something else, thanks.

What the manual is trying to tell you is "Check Engine" means the car is running outside of its normal perimeters, due to a whole variety of reasons, and is no longer meeting emission standards.

You need to get a scan tool hooked up to read the codes. The codes will then point you in the right direction whether it be as simple as a gas cap (evap code) to a cam angle sensor. There are literally hundreds of reasons for a check engine light.

Another note is if the check engine light is flashing while the engine is running, that means there is an active misfire happening on at least one cylinder.

Hope this helps. I bought a scan tool from amazon for why wifes old X3. I think it was around $60 and has been invaluable in diagnosing issues. I just leave it in the glovebox now incase an issue arises.
