I swear, everytime im about to get a new mod something goes wrong. My slk230 Empty Fuel Light came on flashing today, I still have half full tank of gas inside. Soon after the check engine light came on. I pulled over to make sure the gas lid was closed tightly and it was. I restarted the car and the lights came on again 5 minutes down the road (flashing empty fuel light and chk engine light). Whats the cause of this?? Can anyone help me??

Thanks in advance...
