You need to know why it's coming on, dont just reset it. If there is an issue that I'd diluting the oil or blocking the dpd you will need the oil changing or you could wreck the engine. I would take it to the dealer who changed the oil and check they definitely reset after the oil change. If they are unsure I would ask them to change it again and make sure it is reset. Check the oil level has not risen before its changed and smell it doesnt stink of diesel to rule out oil dilution issues.Does one of those oed or obd things reset it ? I ve got one if them off ebay.
Or does it reset itself when you change the oil somehow
