can i just turn the check engine light off?

As Porsche is withholding servicing information from the faithful, like you I came to this forum for support. What I am fast finding is that the folks here are not old school. What does that mean. Well, when something needs attention, if you are old school, you look for answers by the seat of your pants, until you find a good answer that can be shared with the community of folks who enjoy knowing how these beast work. If that means learning a new language, so be it.
