Left my 2010 Mercedes C300 4matic sit for a month with minimal gas-now CEL light
What is your question?
I had my well maintained C300 4Matic with 197000 miles (well maintained).. sitting in the garage because I bought a new car and was planning to sell it. After a month- I turn it on and the CEL light is on. Code: p0300 It was in there with minimal gas and my roommate was turning my car on every few days to move it on the drive way and back so she could workout. She told me she never saw a light until I mentioned it. Could this be because the gas turned bad and is very low? I literally just got a B service done, oil change, and spark plugs/new tires right before I left it in the garage. Trying to sell this but need to figure this out first. Any thoughts?
What makes this problem better or worse?
I don't know. I don't drive it even now. I've left it in the garage.

clear the code out and drive the car a few days to see if it comes back. you will need to drive anyway to get it to pass its monitors after clearing the code.also your going to need to smog it when you sell it. It will not pass smog with a check engine light on or if the monitors are not passed. If you can't clear the code on your own, swing by Street Tech Auto Care and we will clear it for you for free. If the code comes back then you will need a proper diagnostic to isolate the problem, we also can help you with that if you need it.
