Info Request

Welcome and thanks for the question.

Do you know what trouble code was stored in the computer that turn that lamp on? It would be like a P*** where the * is a different number.

Did they simply tell you that there was no code?

a code came up when they hooked into thr obd2 but they didn't tell me what it was

Accepted Answer

That is the code we need to help you.
Anytime a code is set, it helps pinpoint the tech to the possible failed part.
So if the lamp was on and a code was set, then the tech should have not told you that they couldn't find a problem.

Without that code, it would be hard to move on further. I suggest speaking with the dealer to see if the code was written down on the hard copy of your service order.
