Hello,
Last week our check engine light came on and with hopes it was only the gas cap, I tried the gas cap tightening and the light went off. Great. Now, today, my wife is driving it and said the CEL is back on ALSO with the Adblue light. Are these generally correllated? Any advice on the first things I should check? Ive never used Adblue before so should I just put some in and see if that resolves the CEL too?
