My wife just called me to say that her 2011 MCS has an engine cooling fan that is running longer than expected, and the check engine light came on as well. Now, I know that the fan can run a little bit after the engine is shut off, but that CEL is really why she called. She checked out her manual, and this is the one that matches up to "car is still drivable but may have less power than normal" (paraphrase, I don't remember the exact wording ). And until I can get my hands on it, and look for codes with my ScanGauge, I've got very limited info to work with. But, does this sound like anything that anyone else has ever heard of? Anything at all? I'm hoping to avoid a trip to the dealer, since neither of us has the time to do that.
