Before the light came on I had put in engine oil and hadnt replaced the cap properly. The light came on some time after that .I have the cap on properly now .could that have made the light come on
Hi..there..The Oil Cap - normally it shouldnt but it may have cause an initial fault or been picked up as fault with the PCV/Vacuum system so it possible that the reason for the those warning coming up - if the cap has been securely refitted..as long as you havent over filled? - Same with a fault fuel cap loose causing evap fault - it should reset itself after a few cycles on the ignition..there's two choices open..either disconnect the negative terminal on the main battery and leave it off for about 15minutes..then reattach it and see if that helps reset the system..if not then we need to know what the fault codes are..clear them and then re-test drive the car and see if the same fault crops up..if not then fine just leave it at that..if it does then depending on the type of fault and fault codes then you can progress on further checks to sort it out..
