I have a Volvo S60 awd 2.5 2007. The yellow engine light came on and it is to do with the emiissions I found out. My wife did not put the gas cap on tight when she filled up. So it dedected a leak. A Volvo tech said it might take a few days to let the computer go threw the system.
Anyway will the computer turn the light off or do I have to take it to a Volvo dealer, if it was the cap?

If it was the cap it may take a certain number of key cycles to clear, the computer constantly monitors and runs self tests, once that code has passed a certain number(not sure how many on that system) of self tests, the light will clear, (if the cap was the problem). You could wait, or the system can be cleared using a scan tool to erase dtc's.

So at this point you dont even know if the light is on for an evap code or if it came on because there is some other problem? Here is what you can do.
If they are here is what they will do. They will scan the vehicle for fault codes. If a fault comes up as an evap leak then they will check the engine control module to see if it has the newest software? If it does not they will need to download the software. They may just do it for free where they update the ECM, TCM, CEM, DIM, CCM, and REM? But they normally do that when you get a major service? But ask to see if the ECM softare is covered under the extended EMS warranty? That warranty is good for 10years/150k miles. Once they update the software or if the software is current they will run a fuel system quick test. That test will check to see if there is a leak or not. If the test passes you are done. If it fails then you have some other issue like a leaking purge valve, hole in the evap line maybe a bad leak detection pump? But then that is when you will need to pay for some more diagnostic time to get in deeper? So at minimum you should get a free scan and reset to clear the light and a quick test of the evap system assuming that is the fault code that comes up and if needed a free software update? So call them up. Good luck to you and keep us posted.
