Question about 2000 Volvo V40
You cant just turn check engine light off. You have to hook car up to a code reader or scan tool and read trouble codes. Repair trouble codes then erase codes and if problem was repaired check engine light will turn off.

engine light comes on and off, these are indication that there is some
error code stored in your vehicles ECM. The engine module computer
needs to be scanned. These will give the code and as per the error code the
further problem can be detected and confirmed. The engine light
indicator blinks or remains steady on dash when engine computer
noticed any problem with any engine electrically operated components.

The information below was complied by me, it explains what causes the check engine light to come on and the process of finding the cause.
When the Check Engine light (or Service Engine Soon or small picture of an engine) is turned on, the systems computer control unit (called the PCM) has sensed a fault in the electronic controls of the engine and/or the emission system. When this happens you will seldom feel the car engine run any different. There are about 200 possible system faults (the gas cap is just one of them) that turn the Check Engine light on, to know what has developed a problem you must have the system tested, this is called an OBD2 fault code test, Kragen/Oriley and Autozone parts stores (USA only) do this testing for free.
