Mini Cooper S 2007.. what is the trouble code P3018?
JA: Just to clarify, what's the exact code? And have you tried to reset it?
Customer: P3018 is what auto zone gave me when they checked it
JA: Are you fixing your MINI yourself? What have you tried so far?

JA: Anything else you want the mechanic to know before I connect you?
