I have a 2005 Benz C230 kompressor,three days ago i travelled and put in fule but unlike my usual practice i didn't add an injector cleaner,when i got to where i was travelling,i tried accelerating fast and the engine stalled,and the idle speed was not normal,causing the engine to vibrate,and then it showed engine Engine Check,i did a scan and these error codes appeared P0303 and P0620. I have been told this is bad fuel and the error code will go on it's own,is this true? What do these error codes mean and how can i rectify them,thanks.

P0303 is the code for a misfire on cylinder three. P0620 says that there is a problem with the generator control circuit. The misfire probably accounts for the rough running which you experienced. If the problems have been corrected, the codes will go away in time. But most code readers have the ability to erase the codes. If the problems have not been corrected, the codes will return quickly.
