Gas cap light came on after replacing with a new one

Asked by May 18, 2018 at 12:13 PM about the 2013 Volkswagen Passat

Question type: Maintenance & Repair

Gas cap light came on and had our local mechanic order one from
manufacturer for specific year and model.  He replaced and 2 days later my
light came on again.  Is this the same issue or is this related to a new issue?

Unless the gasket in the cap is bad and does not make a good seal there is no need to replace it when the gas cap light comes on, it is usually a cap that has not been screwed in correctly. Have you tried to unscrew the cap and put it back on, slowly? Perhaps the code is still in the computer's memory and all that is necessary is to reset the computer. Ask your mechanic if he performed a reset after installing the new cap, even if the light went off.

Gas cap is not the only thing that will set a check engine light. What was the code??

I am not sure what the code was as they reset the computer after installing the new gas cap. The light went off and came back on the next day when the car was started. Could this be a faulty gas cap?


So, if the light came back read the code again, and write it down!





Code indicates fuel EVAP system leak: Missing or loose fuel cap. Incorrect fuel filler cap used. Fuel filler cap remains open or fails to close. EVAP canister or fuel tank leaks. EVAP system hose leaking. Fuel tank leaking. I would go back to the mechanic, let him remove the gas cap, inspect it well and replace it, then clear the code again, if it comes back then you may also have one of the other conditions.


V.W. Had a issue with the purge valve hanging up.
