Customer Question

the wrench light on my 2012 Ford fiesta came on and said engine malfunction. I took it to o'reileys auto and they ran a code check and nothing cam up. The light is off now.
JA: Do you have the trouble code? Do you have a code reader or scan tool?
Customer: it was a code reader and when they used it it showed no codes. They did it 2 times and both times nothing.
JA: I'll pass this info along to the Ford Mechanic so that he can get you a quick fix. Are you fixing your Fiesta yourself? What have you tried so far?
Customer: it has 47,000 miles on it and I have an extended warranty. I will take to the dealer as son as get back in town.
JA: Anything else you want the mechanic to know before I connect you?
Customer: no
