Service Engine light came on!

Oh well the first warning light came on on my 2012 ML350 with 71k miles today. I bought this in OCT 2019 and had no issues. I had service done at non-MB dealer 6 weeks ago. The car runs fine. Hopefully it's not something major. I check the gas cap and it's tight. any advice? I will scan the OBDI code tomorrow morning. time to sleep. yikes

I scanned the code and it says DTC2 PD/DTC2 I scrolled down and it says Evaporative emission system leak detected(small leak) . Do I need to go to a dealer right away? I have to work today and tomorrow

Have you recently filled the gas tank? Try removing the fuel cap, then replacing it with three clicks. Then drive for a while and see if the CEL goes away.
