I was out running errands today when I noticed upon a restart that my 2019 VW GTI’s idle was erratic, starting off at about 1800 RPM and then decreasing to about 1200 rpm at which speed it fluctuated about 200 rpm up and down. Also, the CEL was lit. I drove to the dealership whose service rep said they could not look at it today, being a Saturday. He said VW said it was OK to drive if the CEL was on without flashing. So I drove it home and parked it. Then I noticed it was leaking oil, so I checked the dip stick which had oil on the very bottom of the stick only. I know it was not leaking oil before driving it, because I checked the floor before parking. Also, I had checked the dip stick the day before. So, can the CEL and the oil leak be related? The car has 8,170 miles.
