+18 2010 Vw Jetta Check Engine Light On References. I turned the car on today to drive to work. If you have a flashing check engine light, turn off the engine immediately to prevent potential motor damage.

The diagnostic port is typically located under the dashboard on the vehicle’s driver’s side. 400 miles later i had the check engine light come on and the car threw a 00315 code. Everything has been good on my car since then, until today.
