My check engine light came on about a month ago and I took it to AutoZone to get the code, and it was a P0299 which has something to do with the turbo. But, a couple of days later the light went off. The light came on again about a week ago, but has just turned off again. Should I still get it looked at, or does the light going off mean the problem is not that serious?

Hello, I'm Danny.

Regardless if the check engine stays on or goes off a code has been stored.Could be the same code or possibly a new one.I would definitely have it checked.Here is a tutorial showing what is involved:

As far as code P0299- turbo under boost is detected.You might be having a problem with the boost pressure sensor. I've attached a description below.Hope this helps and thanks for using 2CarPros.
