Wierd Engine Noise... HELP!
Hey guys I'm new to the forums but I'm currently in a bit of a situation. I got a used C300 sport about 4 months ago and racked up about 3000 miles during that period. Yesterday I noticed a noise coming from the top left of my engine and have no idea what it is. I will be taking it to a mechanic but was hoping someone had this previous problem or knows what it is so I don't get ripped off...
