SES light came on after I filled up my 2003 Disco SE 7. Stopped by autozone and had them run diagnostic check and they stated it was due to the cap being loose because it showed large vacuum in the fuel area. Tightened cap and light still has not cycled off what do I do next?

 

Did they tell you the code? Also you will need a code reader to reset the code. You acan ask them to do it at Autozone but will most likly say NO. Buy a code reader while there.. around 38 bucks, and clear it yourself. All Disco owners need a code reader.

 

Thanks, I had the code read tightened the cap and had it read again and had to manually override code to clear SES light; no more problems with the SES light as of now.
