OK, I know this post is kind of old, BUT - It seems to me that when you handed the dealer the $300, it was under the presumption that the reported problem had been repaired by the service that was performed. Obviously, it was not. That being the case, no additional fees should be incurred by taking it back to the same dealer and forcing them to stand behind their work. It's not your fault that they misdiagnosed the problem. That's bull.
I love how mechanics pull this kind of crap. If I walk my car into a shop for a specific problem and that problem is not corrected by the service that was performed, they either need to correct the problem or refund my money.
I had a similiar situation a few years ago with a car of mine. As soon as I established a court date, my money was refunded.

My check engine light came on about a year ago, I took it into a dealer (its not under warranty) they looked at it, said some minor hose came loose, $300 later they reconnect it, reset the light, fine. A month later, my damn light came back on. Well the dealer was too expensive so I took it to a local mechanic. They had to use a neighboring mechanic for the computer diagnostic, and said that they honestly didn’t understand it, and said that for all they could tell my car was running fine. They reset the light. Yet another month or so later, my light comes back on. Grrrr.
Thanks for any feedback.
