Took it to the dealership, they said it was an EVAP system issue (it had a leak) and they said it was fixed. Today i turned my car on and boom engine light again…any tips please?

 

First you need to get a code reader so you can pinpoint the exact fault. A quick search on Amazon for a OBD2 reader will give you a ton of choices and price options
Most auto parts stores will do this for you too. Once the community here sees the code they will be a wealth of info. Just knowing the light is on is too vague to be much help

 

Yes and tell us what car you have? No details makes it mighty hard to give a good answer?
