Mechanic's Assistant: Are you fixing your vehicle yourself? What have you tried so far?

No I just took it to dealer to run code, then light went off and hasn't come back on

Mechanic's Assistant: Anything else you want the mechanic to know before I connect you?

Can you tell me the actual fault code they retrieved when they ran the scan?

Its possible you may need a new EGR cooler but in most cases, if its bad the light will not go away. Since the light has gone out I would not replace anything and instead, wait and see if the light returns. If it does you can stop by most auto parts store like Auto Zone and they can run a scan for you at no charge. As long as the light is not coming on then the computer is not detecting a problem.

i have a 2014 Malibu. A couple weeks my engine light came on. I brought it into the dealer this evening to get oil changed, tires rotated, and to have engine light code reviewed. They came back and said that the code was P16D0. However after having changed the oil the light went out and didn't come back on. He said it was possibly a faulty intake rocker arm solenoid valve #2. My drive back home took about 30 minutes. I found the light had come back on again. I have to make a 400 mile trip in this car tomorrow! Do you think it is too risky to take the trip in this car now? … read more
