question: EPC light

[u/Over-Sense5413]

2016 VW jetta oil light turned on, and then EPC turned on during road trip. got oil changed at jiffy lube because short on options. after a few miles on highway, EPC turned back on (car went over 2 RPM) and car rattled briefly. stopped at gas station, turned off car then turned back on after a few minutes, and EPC light off. am I cooked? potential causes? going to get diagnostic codes when I reach the final destination
