need advice. P2135 error.
Seven months ago, I had a P2135 come up on my wife's car. We took it in, and they straightened out.
This morning, my wife's check engine light comes back on. I drive her to work, and I go to O'Reilly's and hook up their diagnostic machine to her car. The P2135 error appears. Inadvertently, the check engine light went off.
I used the diagnostic again, and I still get the P2135 error.
I drive over an hour to my dealership, and they aren't willing to help or even look at my car because the check engine light wasn't on. I told them that I had the same issue earlier this year, but still no willingness to help.
I was told to just wait until the check engine light comes back on, and then come back. I called Suzuki's Customer Service, and they pretty much repeated what the dealership said.
My question is since nothing was fixed or even touched, how long will it take for the check engine light to reappear?
